April 25, 2007 — /JCN Newswire/ — TOKYO, JAPAN — Mitsubishi Heavy Industries, Ltd. (MHI) has received an order for nine centrifugal liquid chillers from Hynix Semiconductor, Inc., a major semiconductor manufacturer in Korea. The chillers will be installed in semiconductor production lines being newly added at Hynix’s Icheon Plant for use in air-conditioning its cleanrooms. MHI previously received two orders for high-efficiency chillers from Hynix, 10 units in total, and the latest order will bring the collective number of units ordered by Hynix to 19. Delivery of the chillers is slated for completion by August this year.

The nine centrifugal liquid chillers on order consist of five units with a cooling capacity of 1,600 RT (refrigeration tons*) each, and four units with a 1,000 RT cooling capacity each. These high-performance chillers address environmental concerns by adopting HFC-134a chlorine-free zero ozone depletion potential (ODP) refrigerant as well as reducing CO2 emissions through their high-efficiency and energy-saving features. A microcomputer control system with color TFT liquid crystal display (LCD) enables meticulous and optimized operation management. MHI believes the high evaluation accorded to the outstanding performance of its chillers and the proven operational record of the units previously delivered to Hynix contributed to its winning the latest order.

Hynix Semiconductor is the eighth-largest semiconductor manufacturer worldwide (2006). Through its merger with LG Semiconductor in 1999, the company today boasts the world’s largest DRAM (dynamic random access memory) production capacity. Hynix has recently established a structure for mass-producing 80 nm (nm: nanometer = 1/1,000,000,000 meter) NAND-type flash memories, which are widely used as data storage devices for digital still cameras, mobile phones and portable music players. In 2006, Hynix recorded the highest revenue (7,693 billion won) and net profit (2,055 billion won) in its history. The company now plans to further expand its production capacity by focusing on new growth areas. MHI is looking for its centrifugal liquid chillers to contribute to Hynix’s sustained growth.

Hyundai Climate Control Co., Ltd., a Hyundai Group company that serves as sales agent for MHI’s centrifugal liquid chillers in Korea, has strong business relationships with both Hynix and Hyundai Motor Company, and today it is actively conducting marketing activities to other Korean companies as well. This July, another unit of MHI’s centrifugal liquid chillers with a 2,000 RT cooling capacity is scheduled for delivery to Siltron Inc., a silicon wafer manufacturer belonging to Korea’s LG Group.

MHI is one of the world’s leading manufacturers of centrifugal liquid chillers. It provides various chillers for applications involving building and plant air-conditioning, industrial processing, and district-level heating and cooling. To date the company has received orders from abroad for 160 units of its HFC-134a refrigerant type high-efficiency centrifugal liquid chillers. Gathering momentum from the latest order, MHI will now step up its marketing activities in Korea and other countries in the rapidly expanding East Asia region.

DuPont(TM) Sorona(R) Polymer and Hybrid Membrane Technology receive prestigious IDEA07 Award

April 26, 2007 — /PRNewswire-FirstCall/ — WILMINGTON, DE — Two of the latest technologies from DuPont, one based on bio-based technology and the other based on nanofiber science — DuPont(TM) Sorona(R) polymer and DuPont Hybrid Membrane Technology (HMT), respectively — have received prestigious IDEA Achievement Awards, presented at IDEA07, the International Engineered Fabrics Conference and Expo in Miami Beach, FL.

DuPont(TM) Sorona(R) is the first bio-based, renewably sourced polymer from DuPont. It contains 37 percent renewably sourced materials derived from corn. A breakthrough in polymer science, DuPont scientists developed a way to make Bio-PDO(TM), the key Sorona(R) ingredient, from corn using a new biological process. Whether it’s textile fibers and fabrics for home interiors and apparel, carpeting, or a variety of packaging applications such as films, sealants, foams, and rigid containers, Sorona(R) imparts distinctive, value-added characteristics.

Produced using a proprietary new spinning process, DuPont Hybrid Membrane Technology goes beyond the limits of today’s synthetic and microglass materials with nanofiber media that contain continuous polymeric filaments with a diameter between 100 nanometers and one micron. DuPont Hybrid Membrane Technology makes greater, more selective performance possible across a variety of air and liquid filtration applications, and adds breathability and protection to apparel and bedding products.

As one of the latest innovations from DuPont, Hybrid Membrane Technology (HMT) is a unique offering for air and liquid filtration that is poised to fill the performance gap between traditional nonwovens and microporous films. It also adds unique breathability and protection to apparel and bedding products. When used for energy storage, HMT can significantly improve safety, durability, power and energy performance in a variety of battery and capacitor applications.

“We are proud to be recognized by our peers with this important award, which is even more significant as we only introduced HMT in the second half 2006,” said Matthew Trerotola, vice president and general manager – DuPont Nonwovens. “We believe that nanofiber science that results in developments such as HMT will play a key role in bridging performance gaps of traditional materials, and will lead to advances such as improved air quality, lower energy costs, and extended filter life. There are many significant applications we are exploring for this exciting new innovation.”

“To be recognized by an international organization for the work we have done on Sorona(R) is fantastic,” said Peter Hemken, vice president and general manager – DuPont Bio-Based Materials. “We are seeing increasingly strong demand for materials produced using renewable feedstocks in a variety of market and industry segments, especially those where Sorona(R) offers superior performance benefits such as permanent and natural stain resistance in residential and automotive carpeting and enhanced attributes in apparel. Work is currently under way to introduce additional high performance, renewably sourced materials that will further reduce our dependency on petrochemicals.”

DuPont discovered Sorona(R) in the 1940s but did not commercialize it at the time because of the high cost of the key ingredient propanediol (PDO). A seven-year research program that began in 1993 concluded with the development of a process to make Bio-PDO(TM) from corn sugar. In 2004, a joint venture between DuPont and Tate & Lyle was formed to build, manufacture, and sell this new renewably sourced monomer. The world’s first Bio-PDO(TM) plant in Loudon, TN, began commercial production in November 2006. The process to make Bio- PDO(TM) consumes 40 percent less total energy and reduces greenhouse gas emissions by 20 percent versus petroleum-based propanediol. Production of 100 million pounds of Bio-PDO(TM) through the DuPont Tate & Lyle Bio Products joint venture will save the equivalent of 13.5 million gallons of gasoline per year, or enough to fuel 24,000 cars annually.

The awards, which are co-sponsored by the Association of the Nonwoven Fabrics Industry (INDA) and Nonwovens Industry magazine, honor new product and technical developments since IDEA04 in five categories: Roll Goods, Short-Life End Product, Long-Life End Product, Raw Materials, and Machinery/Equipment. Winners were determined by a vote of industry members.

DuPont — one of the first companies to publicly establish environmental goals 16 years ago — has broadened its sustainability commitments beyond internal footprint reduction to include market-driven targets for both revenue and research and development investment like Hybrid Membrane Technology and DuPont(TM) Sorona(R). The goals are tied directly to business growth, specifically to the development of safer and environmentally improved new products for key global markets.

DuPont is a science-based products and services company. Founded in 1802, DuPont puts science to work by creating sustainable solutions essential to a better, safer, healthier life for people everywhere. Operating in more than 70 countries, DuPont offers a wide range of innovative products and services for markets including agriculture and food; building and construction; communications; and transportation.

When Intel (Santa Clara, CA) recently announced volume manufacturing in the second half of 2007 of a 45 nm process, something was missing: mention of a technology node. Intel isn’t alone in abandoning nodes. The latest International Technology Roadmap for Semiconductors (ITRS) refers to product generation cycles instead.

For those in contamination control, this change could be of more than academic interest. Killer defects have traditionally been defined as a fraction of a node, which is the half pitch of a cell in a memory process or the minimum transistor width in other processes. Thus, the node served as shorthand for a contamination control requirement.


By ditching nodes, semiconductor technologists hope to clean up confusing nomenclature with regard to process linewidths and capabilities. But nodes also provide a measure of contamination control requirements so users of liquid filters-like this one in a European fab-know what they need in the way of performance.

In some ways, that hasn’t changed, says John Goodman, senior vice president and chief technology officer for materials handling company Entegris (Chaska, MN). “The basic rule of thumb of a half linewidth for killer particles is still applicable.”

However, in other ways things have changed because the guideline isn’t always strictly applied anymore. For example, it may be too difficult to develop a filtration membrane to capture particles while maintaining flow. What’s more, the composition of the contaminant may be more important than its size. For those reasons, Goodman says Entegris works with its customers to come up with the right contamination control targets.

As for spotting contaminants, it isn’t always possible to follow a simple node-based formula. The technology to detect particles at low cost and in high volume sometimes doesn’t exist, notes Particle Measuring Systems (Boulder, CO) vice president of marketing John Mitchell.

Thus, those running the 45 nm process might not screen directly for 22 nm contaminants. “There’s no practical way to measure 20 nm particles, particularly in liquids,” says Mitchell.

Instead, he explains, semiconductor manufacturers monitor larger particles. If the distribution of particle sizes doesn’t change and sufficient care is taken in monitoring, this strategy works.

Another consequence of the demise of nodes is that comparisons between processes and contamination control requirements are more convoluted. When evaluating offerings from different manufacturers, Dan McGowan, a spokesperson for SEMATECH (Austin, TX), suggests asking them how their figures of merit, whatever they are, compare to a memory cell’s half pitch. “The answer should help determine how a certain technology advance can be viewed in context with ITRS terminology,” he says.

However, that comparison could be easier to describe than do. Kari Aakre, a spokesperson for Intel, notes that where the company’s technology stands in relation to the technology roadmap depends on which metric is used. She lists such possible measures as transistor gate length, contacted metal pitch, cell size of static random access memory, and others.

While these questions present problems, those who pushed for the dispatch of node nomenclature say the change solves problems. Bob Doering, Senior Fellow and technology strategy manager at Texas Instruments (Dallas, TX), notes company announcements have historically tended to tout process cycles rather than true technology nodes that are 0.7 times the previous generation, a difference that led to trouble in the ITRS. “We were getting almost a whole node out of phase between what we were calling a node and what the common parlance was. So now we don’t use that terminology,” he says.

SAFC completes construction of protein API facilities

SAFC, a member of the Sigma-Aldrich Group, has completed the construction of two new protein active pharmaceutical ingredient (API) facilities at its St. Louis, MO, manufacturing campus. A new biologics manufacturing facility consists of a 25,000 sq. ft. cGMP purification and manufacturing suite for transgenic plant and other non-animal derived protein APIs, and a 6,000 sq. ft. facility for purification of animal-derived protein APIs. Validation for commercial operation of this $16 million expansion at the campus is expected by mid-year.

BIOTECHNICA, INTERPHEX partner for 2008

BIOTECHNICA, Europe’s biggest biotechnology show, is partnering with INTERPHEX, the largest pharmaceutical trade event in North America, in 2008. The co-located event is expected to be the biggest gathering of the life sciences industry on the North American continent. BIOTECHNICA and INTERPHEX will provide an entire spectrum of R&D and upstream and downstream processing technologies. BIOTECHNICA and INTERPHEX debut at The Pennsylvania Convention Center in Philadelphia from March 26-28, 2008.

In the universe of contamination control technology, there are various products and solutions ranging from “high-tech” to “low-tech” offerings. But when it comes to meeting real-world user desires and requirements, this distinction may be irrelevant; some of the most ingenious and beneficial innovations may not appear all that significant at first.

At INTERPHEX, held last month in New York, contamination control companies introduced a plethora of new products that certainly spanned this wide realm, all with one thing in common: They were created in direct response to user feedback and industry needs.

To give just a representative sampling, DuPont, for example, introduced its new “engineered elastic nonwoven” technology, a stretchable, latex-free fabric with varying degrees of elastic recovery power that can be specifically matched to different user requirements. Potential applications include stretchable gown sleeves and cuffs for cleanroom apparel as well as elastic protective covers and interlinings.

Similarly, Kimberly-Clark Professional, which also announced that it will consolidate all of its cleanroom products, including the “Safeskin” glove line, under the “Kimtech Pure” brand name, demonstrated a new pre-saturated wiper dispenser that allows individual one-handed dispensing and incorporates a self-closing/self-sealing lid. The dispenser is part of KC’s complete new line of dry, pre-saturated, and sterile wipers for cleanroom environments.

Also responding to customer feedback, Contec’s new “EasyCurve” mop uses a flat, fabric-laminated head attached to a curved, stainless steel frame with a pivoting connector for easier and more effective cleaning of curved surfaces such as those frequently found in ceilings, walls, and floors of critical environments. The mop uses a separate “sling” style wringer that installs over an autoclavable 6.5 gallon (25 L) polypropylene bucket.

Moving along the line, Pall Corporation rolled out a new collection of fluid management and contamination control technologies specifically targeting the biopharmaceutical industry. The “Allegro” line includes single-use biocontainers for collection and transport of process materials, intermediates, and cell culture media as well as disposable filters, tubing, and aseptic connections. Also introduced were the “KleenPak” self-enclosed, tangential flow (TFF) microfiltration capsule and the “Omega” T-Series membrane cassettes for ultrafiltration of high-purity biological products.

In the electronics technology arena, Johnson Controls announced the expansion of its “Metasys” facility management system for validated environments (MVE). The new version operates on an IT-standard, web services platform and provides secure remote monitoring and data acquisition from a greater number of disparate collection points and systems.

Last but not least, Hach Ultra’s new “Anatel PAT700” TOC water-analysis system incorporates an On-board Automated Standards Introduction System (OASIS), which reduces operator intervention and ensures the instrument is always operating in a validated state. If the analyzer detects a TOC or conductivity value exceeding preset limits during operation, it will automatically save a sample for further analysis.

As you can see, while some of these new products and innovations may seem more glamorous than others, they all provide substantial practical benefit to real-world users. And, in that sense, they are all equally of value to the contamination control community.
