IC Insights is currently researching and writing its 21st edition of The McClean Report, which will be released later this month.  As part of the report, a listing of the 2017 top 50 fabless IC suppliers will be presented.

Figure 1 shows the top 10 ranking of fabless IC suppliers for 2017.  Two China-based fabless companies made the top 10 ranking last year—HiSilicon, which sells most of its devices as internal transfers to smartphone supplier Huawei, and Unigroup, which includes the IC sales of both Spreadtrum and RDA. Fabless company IC sales are estimated to have exceeded $100 billion in 2017, the first time this milestone has been reached.

Unlike the relatively close annual market growth relationship between fabless IC suppliers and foundries, fabless IC company sales growth versus IDM (integrated device manufacturers) IC supplier growth has typically been very different (Figure 2).  The first time IDM IC sales growth outpaced fabless IC company sales growth was in 2010 when IDM IC sales grew 35% and fabless IC company sales grew 29%.  Since very few fabless semiconductor suppliers participate in the memory market, the fabless suppliers did not receive much of a boost from the surging DRAM and NAND flash memory markets in 2010, which grew 75% and 44%, respectively.  However, the fabless IC suppliers once again began growing faster than the IDMs beginning in 2011 and this trend continued through 2014.

In 2015, for only the second time on record, IDM IC sales “growth” (-1%) outpaced fabless IC company sales “growth” (-3%).  The primary cause of the fabless companies’ 2015 sales decline was Qualcomm’s steep 17% drop in sales. Much of the sharp decline in Qualcomm’s sales that year was driven by Samsung’s increased use of its internally developed Exynos application processors in its smartphones instead of the application processors it had previously sourced from Qualcomm.  Although Qualcomm’s sales continued to decline in 2016, the fabless companies’ sales in total (5%) once again outpaced the growth from IDM’s (3%).

In 2017, the market behaved very similarly to 2010, when strong growth in the memory market propelled the IDM IC sales growth rate higher than the fabless IC supplier growth rate.  With the total memory market, a market in which the fabless IC companies have very little share, surging by 58% last year, IDM IC sales growth easily outpaced fabless company IC sales growth in 2017.

The Semiconductor Industry Association (SIA), representing U.S. leadership in semiconductor manufacturing, design, and research, today announced worldwide sales of semiconductors reached $37.7 billion for the month of November 2017, an increase of 21.5 percent compared to the November 2016 total of $31.0 billion and 1.6 percent more than the October 2017 total of $37.1 billion. All major regional markets posted both year-to-year and month-to-month sales increases in November, with the Americas market leading the way. All monthly sales numbers are compiled by the World Semiconductor Trade Statistics (WSTS) organization and represent a three-month moving average.

“The global semiconductor industry reached another key milestone in November, notching its highest-ever monthly sales, and appears poised to reach $400 billion in annual sales for the first time,” said SIA President & CEO John Neuffer. “Global market growth continues to be led by sales of memory products, but sales of all other major semiconductor categories also increased both month-to-month and year-to-year in November. All regional markets also experienced growth in November, with the Americas continuing to post the strongest gains.”

Regionally, year-to-year sales increased in the Americas (40.2 percent), Europe (18.8 percent), China (18.5 percent), Asia Pacific/All Other (16.2 percent), and Japan (10.6 percent). Month-to-month sales increased in the Americas (2.6 percent), China (2.1 percent), Europe (1.8 percent), Asia Pacific/All Other (0.5 percent), and Japan (0.3 percent).

The coldest chip in the world


December 20, 2017

Physicists at the University of Basel have succeeded in cooling a nanoelectronic chip to a temperature lower than 3 millikelvin. The scientists from the Department of Physics and the Swiss Nanoscience Institute set this record in collaboration with colleagues from Germany and Finland. They used magnetic cooling to cool the electrical connections as well as the chip itself. The results were published in the journal Applied Physics Letters.

Even scientists like to compete for records, which is why numerous working groups worldwide are using high-tech refrigerators to reach temperatures as close to absolute zero as possible. Absolute zero is 0 kelvin or -273.15°C. Physicists aim to cool their equipment to as close to absolute zero as possible, because these extremely low temperatures offer the ideal conditions for quantum experiments and allow entirely new physical phenomena to be examined.

Cooling by turning off a magnetic field

The group led by Basel physicist Professor Dominik Zumbühl had previously suggested utilizing the principle of magnetic cooling in nanoelectronics in order to cool nanoelectronic devices to unprecedented temperatures close to absolute zero. Magnetic cooling is based on the fact that a system can cool down when an applied magnetic field is ramped down while any external heat flow is avoided. Before ramping down, the heat of magnetization needs to be removed with another method to obtain efficient magnetic cooling.

A successful combination

This is how Zumbühl’s team succeeded in cooling a nanoelectronic chip to a temperature below 2.8 millikelvin, thereby achieving a new low temperature record. Dr Mario Palma, lead author of the study, and his colleague Christian Scheller successfully used a combination of two cooling systems, both of which were based on magnetic cooling. They cooled all of the chip’s electrical connections to temperatures of 150 microkelvin – a temperature that is less than a thousandth of a degree away from absolute zero.

They then integrated a second cooling system directly into the chip itself, and also placed a Coulomb blockade thermometer on it. The construction and the material composition enabled them to magnetically cool this thermometer to a temperature almost as low as absolute zero as well.

“The combination of cooling systems allowed us to cool our chip down to below 3 millikelvin, and we are optimistic than we can use the same method to reach the magic 1 millikelvin limit,” says Zumbühl. It is also remarkable that the scientists are in a position to maintain these extremely low temperatures for a period of seven hours. This provides enough time to conduct various experiments that will help to understand the properties of physics close to absolute zero.

Tessera Technologies, Inc. (“Tessera”), a subsidiary of Xperi Corporation (the “Company”) (NASDAQ: XPER), today announced that it and certain of its affiliates entered into agreements with Broadcom Ltd. and certain of its affiliates (“Broadcom”), customers, and suppliers to settle and dismiss all pending litigation between them. In conjunction with the settlement, Broadcom entered into a new multi-year patent license agreement with Tessera.

The license agreement provides for an upfront payment in the fourth quarter of 2017 and recurring quarterly payments beginning in the first quarter of 2018. The other terms of the agreements are confidential.

Tessera and Invensas are subsidiaries of Xperi Corporation (NASDAQ: XPER). Over the past 27 years, research and development at both Tessera and Invensas has led to significant innovations in semiconductor packaging technology, which has been widely licensed and is found in billions of electronic devices globally.

Invensas, a wholly owned subsidiary of Xperi Corporation (“Xperi”) (NASDAQ:XPER), today announced the successful technology transfer of its Direct Bond Interconnect to Teledyne DALSA, a Teledyne Technologies company. This capability enables Teledyne DALSA to deliver next-generation MEMS and image sensor solutions that are more compact and higher performance to customers in the automotive, IoT and consumer electronics markets. Teledyne DALSA is a developer of high performance digital imaging and semiconductors and one of the world’s foremost pure-play MEMS foundries. Invensas and Teledyne DALSA announced the signing of a development license in February 2017.

“In partnership with Invensas, we have successfully completed the transfer of its revolutionary DBI technology to our manufacturing facilities in Bromont,” said Edwin Roks, president of Teledyne DALSA. “We are now ready to offer this enabling platform as part of our foundry services to customers, including our own business lines, seeking smaller, higher performance and more reliable MEMS and imaging solutions.”

“The manufacturing team at Teledyne DALSA has done a fantastic job bringing up our DBI process and is well-positioned to enable a new generation of high performance MEMS and image sensor solutions,” said Craig Mitchell, president of Invensas. “We are excited about the prospects for DBI to be integrated into a wide range of Teledyne DALSA’s branded products as well as those of their foundry customers.”

DBI technology is a low-temperature hybrid wafer bonding solution that allows wafers to be bonded with scalable fine pitch 3D electrical interconnect without requiring bond pressure. The technology is applicable to a wide range of semiconductor devices including MEMS, image sensors, RF front ends and stacked memory. DBI 3D interconnect can eliminate the need for through-silicon vias (TSVs) and reduce die size and cost while enabling pixel level interconnect for future generations of image sensors.

Accelerometers and gyroscopes are fueling the robotic revolution, especially the drones’ market segment. However, these MEMS devices are not the only ones on the market place anymore, with environmental sensors penetrating this industry too.

InvenSense, today TDK, combined it: the US-based company, IMU leader and formerly Apple’s supplier during many years, released last month the world’s 1st 7-axis motion tracking device combining accelerometer, gyroscope and pressure sensor. InvenSense announces the ICM-20789 7-axis combo sensor dedicated to mainly drones and flying toys as well as smart watches, wearables, activity monitoring, floor and stair counting etc.

The reverse costing company, System Plus Company has investigated the 7-axis component and technologies selected by InvenSense. Aim of this analysis was to identify the technologies selected by the leading company as well as to understand the impacts on the manufacturing costs.

What are the technical choices made by InvenSense? What are the benefits for the device in term of performances? What is the impact on the manufacturing process flow?

System Plus Consulting’s team proposes today a comprehensive technology and cost analysis, including as well a detailed comparison with the previous generation of combo sensors from InvenSense.

The drone’s market segment dedicated to consumer applications confirms its attractiveness with 23% CAGR between 2016 and 2021. According to Yole Développement, sister company of System Plus Consulting, the market should reach almost US$ 3.4 billion in 2023 (Source : Sensors for drones and robots: market opportunities and technology revolution report, Yole Développement, 2016). Under this dynamic context, System Plus Consulting’s experts are following the technical advances and the evolution of the manufacturing costs of the combo devices. InvenSense’s device is a good example of this technology breakthrough: indeed, for the 1st time, a company presents a 7-axis component combining accelerometer, gyroscope and barometric pressure sensor, integrated on the same package. Innovation clearly is not in the selection of the components, comments the reverse engineering & costing company, but more in the smart combination of the three devices in the same package.

Stéphane Elisabeth, RF and Advanced Packaging Cost Engineer from System Plus Consulting explains: “Using single package integration, the US company merged a 6-axis inertial sensor already identified in iPhone 6 with a barometric pressure sensor based on a design coming from the barometric division of Sensirion. Therefore, InvenSense took benefits of Sensirion’s partial acquisition, taking place in 2016, by developing a specific approach eliminating a package and minimizing board area requirements.”

ILLUS_INVENSENSE_TDK_Combo_CostBreakdown_SYSTEMPLUSCONSULTING_Dec2017

InvenSense was able to integrate its own barometric pressure sensor thanks to the knowledge reached with the acquisition of Sensirion’s barometric division. This device is shipped in a 4 mm x 4 mm x 1.37 mm land grid array (LGA) package.

InvenSense acquired the pressure sensor business from Sensirion Holding AG and its affiliates used in the development of capacitive-type monolithic digital pressure-sensor technology platform.

InvenSense’s financial report highlights the details of this acquisition: the purchase price associated with the acquisition was approximately US$9.8 million, of which US$5.7 million was allocated to developed technology with an estimated useful life of six years and US$4.1 million was allocated to goodwill.

Faced with this simple but impressive technical innovation, what will be the answer of other MEMS & Sensors manufacturers? Will this combination of IMU with barometric pressure sensor be followed by competitors? The selling prices of IMUs have fell in recent years and adding new functions is a way to keep a profitable ASP.

Semiconductor test equipment supplier Advantest Corporation (TSE:6857) has developed the M4171 handler to meet the mobile electronics market’s needs for cost-efficient thermal control testing of ICs with high power dissipation during device characterization and pre-production bring up.  This portable, single-site handler automates device loading and unloading, thermal conditioning and binning in engineering labs, where most testing today involves manual device handling. It also features an active thermal control (ATC) capability typically available only on larger footprint, more costly production-volume handlers.

The M4171 can be used to remotely conduct device handling and thermal control from anywhere around the world through a network connection.  In addition to requiring fewer operators and lowering labor costs, this handler maximizes system utilization among working groups in different locations.

The combination of automated device handling, wide-temperature ATC capabilities from -45° C to 125° C and remote operation make the M4171 unique.  It can run multi-mode test processes (Single Insertion Multiple Temperature), automated testing, automatic ID testing, output tray re-testing and manual testing, both pre-defined and user defined.

The Tri Temp Technology on the M4171 enables the users to operate over a broad range of temperatures which greatly increases any lab’s efficiency.  The system uses direct device-surface contact, which enables quick temperature switching for fast ramp up and ramp down and improves cycle temperature testing by over 40 percent compared to manual thermal-control solutions.

The M4171 handler is compatible with the V93000 and T2000 platforms as well as other testers.  Other features include a 2D code reader, a device rotator and a high contact force option.  Operation is simple with an intuitive, easy-to-use GUI that includes pre-defined functions.

“By bringing cost-efficient automated testing into the lab and enabling our customers to get higher utilization from their installed base, we are providing substantial productivity advantages,” said Toshio Goto, executive officer and manager of the Device Handling business unit at Advantest.  “As our first single-site ATC handler, the M4171 is opening new market opportunities for us in device characterization within labs and benchtop environments.”

 

InfinityQS International, Inc. (InfinityQS), the global authority on data-driven manufacturing quality, announces TEL NEXX, a metallization solutions provider to chip designers and manufacturers, is using its software to modernize shop floor data collection and quality control. Moving from a manual, paper-based system to an accessible database, the company has installed InfinityQS’ Quality Intelligence solution ProFicient on tablets for shop floor operators to directly enter data. This has improved the accuracy and timeliness of data capture and enabled rapid response to production issues. With access to historical data at the management level, TEL NEXX can also identify opportunities for quality and process improvements.

Brian Hart, Manufacturing Engineer, TEL NEXX, said, “ProFicient has made accessing a history for each product easy. As our database grows, we can extract information to drive continuous improvement projects and eliminate bottlenecks. What’s more, moving from a paper-based system to an accessible database has made us more efficient. As the projects and operators advance, we only expect to move faster and faster—with the same integrity.”

Historically, TEL NEXX collected data almost entirely manually, which required operators to duplicate data-entry steps by recording data on paper and then entering them into spreadsheets. These processes were time consuming and required rechecking to avoid errors. But now, operators are entering data once into ProFicient, and the data immediately becomes available for managers and administrators to review and provide feedback in real time. Direct data entry has also improved morale on the shop floor, with operators seeing the importance of data collection and taking greater ownership of the work.

Michael Lyle, President and CEO, InfinityQS, said, “When manufacturers rely on manual data entry, it creates inefficiencies that prevent them from responding to variations and other shop floor issues properly and in a timely manner. Instead, modern technologies are available that can create visibility for organizations into their quality data. This transparency enables them to not only make prompt corrections to ensure problems don’t compound, but also perform proactive analysis for continuous improvement.”

To support operator adoption, Hart is leading an incremental rollout of ProFicient and also gradually integrating the solution with TEL NEXX’s existing shop-floor systems. Notably, within just weeks of deploying ProFicient, Hart was able to detect equipment settings that had been inadvertently altered from the original specifications and in a few hours make adjustments so that the machine operated correctly moving forward.

SkyWater Technology Foundry announces that it has been assigned the Specialty Foundry customer relationships from Cypress Semiconductor Corporation. The customer relationships were already being serviced within SkyWater’s 200mm semiconductor wafer manufacturing facility when purchased from Cypress earlier this year. Through the transaction, SkyWater assumes ownership of Cypress’ current embedded Specialty Foundry customer engagements and adds associated business management personnel.

“This transaction builds upon the concept of a Technology Foundry, which enables customers to design, build, and scale their products by simplifying the realization of complex technologies through access to semiconductor technology, experienced personnel and volume manufacturing capabilities,” said SkyWater Chairman of the Board Gary Obermiller. “The addition of the Specialty Foundry customers is synergistic with our pure-play Technology Foundry model; customers come to us with their ideas and we transform them into practice through the application of our differentiated semiconductor technology and operational expertise.”

The Technology Foundry Business model enables customers to design and optimize their product concepts. In tandem with SkyWater’s advanced wafer manufacturing facility, customers are able to prototype and rapidly scale to production volumes, all inside of a high-yield production fab.

“The Specialty Foundry Business was created in 2008 with the vision of providing advanced development access to a high-volume production-scale fab, building on the site’s proven track record of success in bringing new technologies to production,” said Michael Moore, executive vice president of Sales and Marketing at SkyWater. “It’s in our DNA. We’ve been doing development work at this site for decades, right alongside production.  This move is a natural next step for the company and our customers.  We have successfully diversified the customer base this way, by serving new and unique markets that are poised for rapid growth.”

As part of the assignment, which closed October 2, SkyWater will now have direct responsibility for all Specialty Foundry Business customers, eliminating the prior Cypress interface. Because of the existing working relationship between all parties, there will be a seamless transition for all current projects; the same team will continue working with all existing customers, the only difference being that they are now SkyWater employees.

Within SkyWater’s manufacturing facility there are a wide variety of unique technologies currently being developed and manufactured – from superconducting quantum computers to advanced technology Readout IC’s (ROIC), MEMS-based infrared imagers, DNA sequencing and fabrication platforms, and photonic integrated circuit (PIC) devices.

According to SkyWater’s Senior Director of Sales Brad Ferguson, “These types of Technology engagements just start with a simple conversation about our capabilities, and once Customers see the potential of our Technology Foundry solution, they realize this is the right place to transform their concepts into a manufactured product.”

SkyWater is a U.S.-based technology foundry specializing in the development and manufacturing of a wide variety of semiconductor based solutions.

Leti, a research institute of CEA Tech and coordinator of the pan-European consortium FED4SAE, today announced that the 14 project partners have launched a three-year European Commission program to facilitate the acceleration of European cyber-physical-system (CPS) solutions to market. This project will boost digitization of European industry by strengthening companies’ competitiveness in the CPS market.

Cyber-physical systems link the physical world (e.g., through sensors or actuators) with the virtual world of information processing. They are comprised of diverse constituent parts that function together to create some global behavior. These constituents may include software systems, communications technology, and sensors/actuators that interact with the real world, often including embedded technologies.

The FED4SAE project, launched in September in Grenoble, will create a pan-European network of Digital Innovation Hubs (DIH) by leveraging existing regional tech or businesses ecosystems across complete value chains and multiple competencies. The network of DIHs will enable startups, SMEs and midcap companies in all sectors to build and create new digital products, smart applications and services. The project mission also includes innovation management – linking these companies to suppliers and investors to create innovative CPS solutions and accelerate their development and industrialization.

“FED4SAE will give birth to a competitive ecosystem that will help European startups, SMEs and midcaps innovate and thrive as they access leading technology sources, competencies and industrial platforms,” said Leti project coordinator, Isabelle Dor. “The network will also effectively link them to well-connected business infrastructures, such as banks, investors and business accelerators, and existing regional innovation hubs.

“Bottom line: the expanded adoption of CPS solutions offered by the network is expected to lead to quantifiable increases in the participating companies’ market share, productivity and industrial capacities,” Dor said.

The FED4SAE project will fund industrial projects thanks to the cascade-funding process set by the European Commission. There will be three open calls over the course of the project. The first call, which opens Nov. 14, will support the best projects based on their innovation potential and technical expertise, the maturity of the solution, with technology-readiness levels between 3 and 6, and their efficient management of the innovation to create a lasting impact with the developed solution.

This pan-European network will enable companies to use CPS platforms combined with expertise and knowhow from the R&D advanced platforms. The ultimate goal of each industrial project within FED4SAE is to develop a complete solution that can get to market and scale.

This includes combining hardware and software components and deploying them in a range of testbeds prior to deployment into the targeted market, as well as support in business modeling and market insights through guidance from conceptual design through market launch. Application experiments will be funded for developing innovative CPS products that will increase the competitiveness of European innovative companies.

Proposals can be submitted from Nov. 14 to Feb. 6, 2018, for the first open call. The expected average funding per applicant is €50,000 with a maximum of €60,000 for one application experiment.
