After experiencing runaway growth in recent years, the OLED display market is gearing up to make another big leap. Flexible OLED technology is expected to bring about an unprecedented change in flat displays which have ruled the display market for the last 20 years since the emergence of a liquid crystal display. Flexible OLED technology has already been introduced in a series of exhibitions and conferences for the last few years, and it is expected to make an innovative change in the conventional display industry structure once commercialized.

Unlike the conventional rigid OLED screen, the flexible OLED panel refers to the OLED display with flexibility. It is a very attractive product concept in that flexible OLED technology enables consumer goods manufacturers to develop applications in a variety of shapes to maximize its usability. For panel makers, the technology can cut manufacturing costs and simplify manufacturing processes by minimizing the use of glass substrates.

In order to produce a flexible OLED display, alternative substrate materials and encapsulation process to a conventional glass substrate are required. Until before 2010, most prototypes had used a metal foil substrate. But the trend recently shifted to a flexible OLED panel using a plastic substrate because the metal foil substrate has a rough surface and lacks flexibility. A wide range of methods are also being studied to develop alternative encapsulation techniques encompassing the use of plastic film and thin-film deposition technologies.

Still, technological approaches vary depending on panel makers. Performance of a flexible OLED display, productivity and costs change significantly depending on flexible materials and manufacturing techniques which could also determine the marketability of flexible OLED displays. Therefore, there is a big difference in the time frames under which each panel maker plans to enter the flexible OLED market.

At this point of time, the “Flexible OLED Competitiveness and Market Forecasts” report from Displaybank, now part of IHS Inc., analyzes strategies taken by each panel maker for a flexible OLED display to take root in the display panel market, as well as various relevant technological issues. It discusses the growth potential of flexible OLED panels in the existing display market at the current point in time. This report is expected to help panel makers set a plan on how to approach the flexible OLED market in terms of technologies and come up with appropriate strategies to make a successful foray into the conventional display market with flexible OLED technology.

In its Research Bulletin dated August 2, 2013, IC Insights published its list of the top semiconductor sales leaders for the first half of 2013. The list showed the usual big-time players that we’ve come to expect like Intel, Samsung, and TSMC, leading the way in semiconductor sales through the first six months of the year. What stood out nearly as much, however, was that only one Japanese company—Toshiba—was present among the top 10 suppliers through the first half of 2013.  Anyone who has been involved in the semiconductor industry for a reasonable amount of time realizes this is a major shift and a big departure for a country that once was feared and revered when it came to its semiconductor manufacturing presence on the global market.

Figure 1 traces the top 10 semiconductor companies dating back to 1985, when Japanese semiconductor manufacturers wielded their influence on the global stage.  That year, there were five Japanese companies ranked among the top 10 semiconductor suppliers.  Then, in 1990, six Japanese companies were counted among the top 10 semiconductor suppliers—a figure that has not been matched by any country or region since.  The number of Japanese companies ranked in the top 10 in semiconductor sales slipped to four in 1995, then fell to three companies in 2000 and 2006, two companies in 2012, and then to only one company in the first half of 2013.

It is worth noting that Renesas (#11), Sony (#16), and Fujitsu (#22) were ranked among the top 25 semiconductor suppliers in 1H13, but Sony has been struggling to re-invent itself and Fujitsu has spent the first half of 2013 divesting most of its semiconductor operations.

Japan’s total presence and influence in the semiconductor marketplace has waned.  Once-prominent Japanese names now gone from the top suppliers list include NEC, Hitachi, Mitsubishi, and Matsushita. Competitive pressures from South Korean IC suppliers—especially in the DRAM market—have certainly played a significant role in changing the look of the top 10.  Samsung and SK Hynix emulated and perfected the Japanese manufacturing model over the years and cut deeply into sales and profits of Japanese semiconductor manufacturers, resulting in spin-offs, mergers, and acquisitions becoming more prevalent among Japanese suppliers.

  • 1999 — Hitachi and NEC merged their DRAM businesses to create Elpida Memory.
  • 2000 — Mitsubishi divested its DRAM business into Elpida Memory.
  • 2003 — Hitachi merged its remaining Semiconductor & IC Division with Mitsubishi’s System LSI Division to create Renesas Technology.
  • 2003 — Matsushita began emphasizing Panasonic as its main global brand name in 2003.  Previously, hundreds of consolidated companies sold Matsushita products under the Panasonic, National, Quasar, Technics, and JVC brand names.
  • 2007 — To reduce losses, Sony cut semiconductor capital spending and announced its move to an asset-lite strategy—a major change in direction for its semiconductor business.
  • 2010 — NEC merged its remaining semiconductor operations with Renesas Technology to form Renesas Electronics.
  • 2011 — Sanyo Semiconductor was acquired by ON Semiconductor.
  • 2013 — Fujitsu and Panasonic agreed to consolidate the design and development functions of their system LSI businesses.
  • 2013 — Fujitsu sold its MCU and analog IC business to Spansion.
  • 2013 — Fujitsu sold its wireless semiconductor business to Intel.
  • 2013 — Elpida Memory was formally acquired by Micron.
  • 2013 — After failing to find a buyer, Renesas announced plans to close its 300mm and 125mm wafer-processing site in Tsuruoka, Japan, by the end of 2013.  The facility makes system-LSI chips for Nintendo video game consoles and other consumer electronics.
  • 2013 — Unless it finds a buyer, Fujitsu plans to close its 300mm wafer fab in Mie.

Besides consolidation, another reason for Japan’s reduced presence among leading global semiconductor suppliers is that the vertically integrated business model that served Japanese companies so well for so many years is not nearly as effective in Japan today.  Due to the closed nature of the vertically integrated business model, when Japanese electronic systems manufacturers lost marketshare to global competitors, they took Japanese semiconductor divisions down with them.  As a result, Japanese semiconductor suppliers missed out on some major design win opportunities for their chips in many of the best-selling consumer, computer, and communications systems that are now driving semiconductor sales.

It is probably too strong to suggest that in the land of the rising sun, the sun has set on semiconductor manufacturing.  However, the global semiconductor landscape has changed dramatically from 25 years ago. For Japanese semiconductor companies that once prided themselves on their manufacturing might and discipline to practically disappear from the list of top semiconductor suppliers is evidence that competitive pressures are fierce and that as a country, perhaps Japan has not been as quick to adopt new methods to carry on and meet changing market needs.

Anapass, Inc, a display SoC solution provider, today announced that it has successfully completed development of a leading-edge panel controller system on chip “SoC” for UHD TV applications and has recently started mass production. As a result of the successful commercialization of a competitive panel controller SoC for UHD TV, Anapass will be well positioned as a leading panel controller provider for the rapidly growing next generation world-wide TV market, UHD TV.

According to a market research report produced by SNE Research in May 2013, the number of worldwide TV shipments forecasted for this year is 235.1M, 2.6M units of which are expected to be UHD TVs. This year is the first to show significant emergence of UHD TVs as the next generation TV. According to the report, between this year and 2016, the UHD TV market is expected to rapidly grow with 191 percent of CAGR, therefore nearly doubling every year.

The rapid growth of the UHD TV market is reflecting the recent market situation in which the world’s leading flat panel TV makers are aggressively expanding their UHD TV line up from premium high-end TVs down to high volume, smaller panel size TVs ranging from 50 to 60 inch. As such, the UHD TV market is expected to have very aggressive growth. In addition, the swift evolution of the UHD (3840 x 2160) video content eco-system, which provides four times higher resolution than FHD (1920×1080) is strongly supporting the emergence of the UHD TV market era.

Anapass said it intends to leverage its technical know-how and experience in developing and launching panel controller products for flat panel TVs for leading the commercialization of next generation panel controller products optimized for the rapidly growing UHD TV market. Anapass said it is expecting that this will significantly contribute to continuous growth of its core panel controller business.

M/A-COM Technology Solutions Holdings, Inc., a supplier of high performance RF, microwave, and millimeter wave products, today announced it has filed suit in the United States District Court for the Northern District of California against GigOptix, Inc. (NYSE MKT:GIG) for patent infringement.

The complaint alleges that GigOptix makes, uses, imports, offers to sell, and/or sells in the United States electro-optics polymers containing chromophores that infringe two MACOM patents, including certain GigOptix Mach-Zehnder modulator products that GigOptix markets or promotes as containing "Thin Film Polymer on Silicon (‘TFPS(TM)’)" technology. MACOM is seeking injunctive relief barring the infringement, as well as monetary damages, including treble damages based on allegedly willful infringement by GigOptix, attorney’s fees and costs of suit.

"MACOM has built a substantial patent portfolio through investment in innovation, and will defend that investment vigorously when required," said Ray Moroney, Optoelectronics Product Line Manager for MACOM. "We look forward to a just resolution of this matter through the legal process."

Printed electronics refers to a process in which printing technology is used to produce various kinds of electronics goods, such as electronic circuits, sensors and devices. Printed electronics is emerging as a technology that will replace traditional photolithography, which requires costly materials, complex processes and expensive equipment, for the production of simple circuits or electronics components. In addition, printing technology allows patterning a desired substance on a specific location without complex processes. 

According to the “Emerging Displays Report – Printed Electronics Technology – 2013” report, published by IHS, the applied market for printed electronics is forecast to gradually grow after 2015. The total applied market created by printed electronics technology is expected to grow at a compound annual growth rate (CAGR) of 47 percent to $24.3 billion by 2020 from $3.3 billion in 2013.

The global printed electronics market is expected to grow in sync with the opening of the flexible display market. Currently, the technology is commercially applied to touch panel sensors and FPCBs, which have relatively low entry barriers. With partial application to RFIDs, smart tags, LCDs and OLEDs, the technology will gradually expand its application to the fabrication of flexible displays and thin film photovoltaics.

Whereas the current display industry has developed its technology and products centered on scaling-up to large sizes and realizing high-resolution images, the future industry development direction is expected to focus on flexible displays. Compared to the conventional glass substrate, flexible displays are thinner, lighter, and less prone to break. With such properties, it is expected that flexible electronic devices will be able to replace the existing market as well as create new ones.

The flexible (thin glass, metal thin film, plastic) substrate is gaining importance as a key component that determines the processability, performance, reliability, and price of flexible displays. To this end, IHS Electronics & Media publishes a Flexible Display Substrate Technology report to analyze the technology development, industrial conditions, and R&D trends of flexible substrates.

According to the report, the flexible substrate market is forecast to grow to $506.7 million by 2020 from a $2.5 million in 2013. The OLED display, another market that can be created by applying the flexible substrate technology, is expected to make up 91 percent of the overall market.

Booming demand for low-priced 7.x-inch products helped shipments of panels used in media tablets to more than double in in the first quarter, according to an the new report entitled “Tablet PC Touch Panel Shipment Database” from information and analytics provider IHS.

Global shipments of capacitive touch screen displays for media tablets amounted to 45.2 million units in the first quarter. This represented a remarkable 111.9 percent increase compared to the same period last year, more than doubling the 21.3 million total in the first quarter of 2012. While shipments were down 13 percent compared to the fourth quarter, such a seasonal decline is typical for electronics in the first quarter.

“Sales of smaller-sized tablets are rising at a rapid rate, driving shipments of capacitive touch screen displays ranking in size from 7- to 8-inches,” said Duke Yi, senior manager for display components and materials research at IHS. “These tablets are inexpensive, with pricing at $199, making them popular among consumers. With the level of competition increasing in both the tablet and panel markets, pricing is expected to continue to decline, boosting shipments of displays and end products in this size range.”

With the increasing number of panel makers, the average selling price (ASP) of tablet PC touch panel modules is falling at a fast rate. In the first quarter of 2013, average pricing of 7.0-inch tablet touch panels fell to $15.60, down a sharp 16 percent from $18.60 in the first quarter of 2012. Pricing for 7.0-inch touch panels dropped by 7.5 percent from $15.60 in the fourth quarter, the largest sequential percentage decrease of any size.

At the end of the first quarter of 2013, display supplier TPK achieved a 29 percent market share in the tablet touch screen market because of its strong cadre of leading stable clients, such as Apple, Amazon, Barnes & Noble, Microsoft and Asus—including the Nexus 7. This gave the company the leading position in the tablet touch panel market in terms of unit shipments.

The runner up was Iljin Display, the biggest supplier of tablet PC touch panels for Samsung Electronics, which accounted for 15.5 percent of market shipments in the first quarter of 2013, up from 7.5 percent in the first quarter of 2012.

GIS, the touch panel subsidiary of Foxconn Technology Group, is steadily increasing its supply of touch panels for Apple Inc.’s iPad and iPad mini. At the same time, GIS is supplying 8.9-inch touch panels for the Amazon Kindle Fire HD.

On the strength of these deals, GIS in the first quarter attained a 13.3 percent share of shipments, up from 12.8 percent in the fourth quarter, and just 7.5 percent in the first quarter of 2012.

Wintek once held the second place in the market because it shared in supplying of touch displays for the Apple iPad with TPK. However, with the rise of GIS, Wintek’s share has fallen. The company’s market share plummeted to 8.5 percent in the first quarter of this year.

Meanwhile, China’s O-Film quickly reacted to the low-priced 7-inch tablet PC touch market, resulting in the company making great strides quarter after quarter. The company at the end of the first quarter in 2013.arrived in Top 5 with an 8.5 percent market share.

The market for semiconductors used in industrial electronics applications relished a better-than-expected first quarter as macroeconomic headwinds turned out to be less severe than initially feared, according to the latest Industrial Electronics report from information and analytics provider IHS.

Worldwide industrial electronics chip revenue in the first quarter reached $7.71 billion, up 1 percent from $7.63 billion in the final quarter of 2012. Although the uptick seemed modest, the increase marked a turnaround from the three percent decline in the fourth quarter. It also represents a major improvement compared to the 3 percent contraction of the market a year ago in the first quarter of 2011, as shown in the figure below.

 

“The industrial semiconductor market’s performance was encouraging, especially in light of continuing global economic uncertainty and the seasonal nature of the market, which typically sees slower movement in the first quarter of every year,” said Robbie Galoso, principal analyst for electronics at IHS. “Some large segments of the industry, particularly avionics and oil and gas process-automation equipment, saw muscular double-digit gains, helping to drive up overall revenue.”

In another positive development, several large industrial semiconductor suppliers also reported very lean inventories because of strong orders from customers. Infineon Technologies of Germany, Analog Devices of Massachusetts, and Dallas-based Texas Instruments all posted a sequential decline in industrial chip stockpiles as their days of inventory (DOI) measure fell well below average. Infineon achieved higher sales from increased volume in isolated-gate bipolar transistor (IGBT) chips; Analog Devices was strong in factory automation and medical instrumentation; and Texas Instruments saw growth in its analog products.

Other companies reporting sound increases during the period were Xilinx of California for its test and measurement, military aerospace and medical product lines; and Microsemi, also from California, which likewise enjoyed expansion in medical electronics along with broad-based growth for the period.

Europe’s woes inhibit industry, but China counters with growth

However, the industry was not without its challenges, with the Eurozone crisis causing the most havoc.

“The financial troubles on the continent, particularly in Greece, Italy and Spain, had the effect of stifling growth as a whole, especially in the commercial market for building and home control,” Galoso said. “As a result, the individual sectors for lighting, security, climate control and medical imaging were deleteriously impacted in the first quarter, compared to positive performance for those areas in the fourth quarter of 2012.

In contrast to Europe’s woes was China, which displayed growth momentum and much-improved demand across a number of industrial end markets. Manufacturers like Siemens of Germany, Philips of the Netherlands, Swiss-based ABB and Schneider Electric of France said their first-quarter sales in China improved from the earlier quarter.

In the rare earth industrial sector, however, China’s hold on the market loosened as rare earth prices started going south this year. China had a more than 90 percent monopoly on rare earth elements in the past, but new sources in Australia, the United States, Brazil, Canada and South Africa have opened up the market, decreasing dependence on China.

Products that incorporate rare earth materials include wind turbines, rechargeable batteries for electric vehicles and defense applications, including jet-fighter engines, missile guidance systems, and space satellites and communications systems.

Aerospace flies high; oil and gas equipment is also a winner

The military and civil aerospace market had the most robust performance among all industrial semiconductor segments in the first quarter. Avionics was especially vigorous, driven by commercial aircraft sales from pan-European entity EADS Airbus and U.S. maker Boeing, up 9 percent and 14 percent, respectively, on the quarter.

The oil and gas exploration market also saw solid revenue growth, with strong subsea systems and drilling equipment driving sales for ABB, Honeywell and GE.

In contrast to those high-performing segments, lackluster sales were reported in the markets for building and home control, for energy generation and distribution, and for test and measurement. One other market, manufacturing and process automation, reported stable growth, even though its sector for motor drives remained in negative territory.

Two NJIT researchers have demonstrated that using a continuum-based approach, they can explain the dynamics of liquid metal particles on a substrate of a nanoscale. "Numerical simulation of ejected molten metal nanoparticles liquified by laser irradiation: Interplay of geometry and dewetting," appeared in Physical Review Letters (July 16, 2013).

The evolution of fluid drops deposited on solid substrates has been a focus of large research effort for decades, said co-author Shahriar Afkhami, an assistant professor in the NJIT Department of Mathematical Sciences. This effort has become particularly extensive on the nanoscale, due to the relevance of nanostructures in a variety of fields, ranging from DNA sequencing to plasmonics and nano magnetism. And the research also applies to liquid crystal displays and solar panel designs."

In this work, Afkhami with NJIT Professor Lou Kondic, also in the Department of Mathematical Sciences, studied the liquid metal nanostructures placed on solid substrates. The study is of direct relevance to self- and directed-assembly of metal nanoparticles on surfaces. For example, the size and distribution of metallic particles strongly affects the yield of solar cell devices, Afkhami said.

In this work, however, the researchers demonstrate that using a continuum-based approach is appropriate on the nanoscale, where the basic assumptions of continuum fluid mechanics are pushed to the limits. The pair’s research is the first attempt to utilize state-of-the-art simulations based on continuum fluid mechanics to explain the dynamics of liquid metal particles on a substrate on the nanoscale.

"We demonstrated that continuum simulations provide a good qualitative agreement with atomistic simulations on the length scales in the range of 1-10 nm and with the physical experiments length scales measured in the range of 100 nanometers," added Kondic.

Kondic is involved in the mathematical modeling and simulating of granular materials, as well as in development of numerical methods for highly nonlinear partial differential equations related to the flows of thin liquid films. In 2005, Kondic received a Fulbright Foundation grant and traveled to Argentina to study the dynamics of non-Newtonian liquid films involving contact lines. He currently leads four federally funded projects totaling more than $800,000.

Afkhami uses computational and mathematical modeling to help researchers better understand a range of real-life engineering phenomena. His work includes examining biomedical systems, polymers and plastics, microfluidics and nano-materials. His research looks for the existence of solutions and issues involving fluid flows from stability to asymptotic behavior.

Afkhami’s current research project is to numerically discover a better way to understand the dynamics of mixtures of fluids. The effort will tie into his new three-year NSF $252,000 grant (2013-16) to develop a state-of-the-art computational framework for polymeric liquids. The fruits of this labor will eventually have a broad effect in complex applications, such as how blood and other bodily fluids flow in microfluidic devices as well as finding better ways to improve the flow of emulsions when blending or processing polymers.

Photoresists are primarily used in the electronics industry and in high demand from the semiconductor and liquid crystal display (LCD) sectors where photolithography is a main manufacturing process. Photolithography is a very important process during chip fabrication and makes up a large portion of production costs. Although it varies depending on semiconductor types, the photolithography process generally accounts for 30 percent of memory chip manufacturing costs and 60 percent of total production time.

Reflecting the trend toward microfabrication in the semiconductor industry, photoresists have emerged as core materials. Organic photosensitive material producers, which have been participating in the industry from the beginning, are leading the development of photoresists. Those companies include JSR Corp., Tokyo Ohka Kogyo Co. Ltd. (TOK), Dow Chemical Co. (formerly Rohm and Haas Co.), Shin-Etsu Chemical Co. Ltd., Sumitomo Chemical, and AZ Electronic Materials (AZEM). All major photoresist suppliers run their businesses in South Korea where the world’s top LCD and semiconductor manufacturers are based. In particular, most of major photoresist companies make every effort to supply their products to Samsung Electronics Co. Ltd., as it could serve as a guarantee of product quality. Samsung has the most advanced semiconductor fabrication processes in the sector.

The consumption of photoresists by the South Korean semiconductor industry was estimated at $240 million in 2012, down from 2011 in value due to a drop in shipment volume, and it will decline further to $220 million in 2013. With the prospective adoption of high-end extreme ultraviolet (EUV) photoresist in 2014, the photoresist market is expected to post an annual growth of more than five percent in value going forward, despite a minimal volume growth.

The number of wafer inputs into semiconductor fab lines has barely changed since the industry is increasingly adopting microfabrication process. Despite anemic growth in photoresist demand compared with the chip output increase, the rising portion of high-end ArF resists will push the photoresist market higher in terms of value.
