June 5, 2012 — W. L. Gore & Associates and CT Associates developed a method for measuring <50nm particles in ultra-pure water (UPW) used in semiconductor processes, and removing particles as small as 12nm, through a combination of ultrafiltration and microfiltration.
Small particles contaminating UPW can cause defects on the semiconductor wafer, and must be removed by filtration. At leading-edge nodes, semiconductor UPW must be free of particles above 10nm in diameter. Conventional particle counting instrumentation cannot measure particles this small.
W.L. Gore and CT Associates developed a particle detection technique that allows filter makers to measure retention efficiency for such small particle sizes in the lab. A precise aerosol is created from the UPW and evaporates the water, leaving the particles behind in the gas phase. These particles can then be accurately sized and counted using conventional aerosol particle detection instrumentation.
This method was used to evaluate filters from common UPW systems at semiconductor fabs. Although ultra filters have high retention efficiency, some very small particles can still pass through and create defects.
The test method showed that a very high retention micro filter is able to retain a large fraction of the small particles as well.
The researchers concluded that an overall filtration system using both an ultra filter and a high-retention micro filter in series will better retain defect-causing particles from UPW, in sizes as small as 12nm diameter.
W.L. Gore and CT Associates share the results of this study in a white paper, “Removal of 12nm particles from UPW by a combination of Ultrafiltration and Microfiltration,” by Donald C Grant and Dennis Chilcote, CT Associates, Inc., and Uwe Beuscher, W. L. Gore and Associates, Inc., is available online in the May/June issue of ULTRAPURE WATER Journal, http://www.ultrapurewater.com/UPW/Default.aspx, and will be presented at the ULTRAPURE WATER-Micro conference, November 13-14, in Phoenix, AZ.

June 4, 2012 — The ConFab 2012, Solid State Technology’s invitation-only meeting of the semiconductor industry, opened today in Las Vegas with a keynote address from John Chen, PhD, VP of technology and foundry operations at Nvidia Corporation. Nvidia makes graphics processing units (GPUs) and other semiconductor chips and is listed on the NASDAQ under ticker NVDA.
Chen presented the “virtual IDM” concept in his talk, “The Next Transformation of the Semiconductor Industry.” Integrated device manufacturers (IDMs) take semiconductor chips from design to wafer fab to packaging and final sale. The virtual IDM is a way for semiconductor foundries, fabless companies, and outsource semiconductor assembly and test (OSAT) houses to collaborate to solve the new challenges in technology, manufacturing and business. Instead of 1 company performing chip design, fab, and packaging, the 3 companies (or many more) work in concert to both excel in their area of expertise and seamlessly coordinate with the other elements to act as one.
Chen has experience in IDM, foundry, and fabless companies, with 35 years spent in the semiconductor industry. Prior to his time at NVIDIA, Chen held senior executive positions at FlexICs Inc., TSMC, WaferTech LLC, and Cypress Corporation. He started out with Hughes Research Lab and Xerox Palo Alto Research Center, where he authored more than 100 research papers on CMOS technology, as well as a book published by Prentice Hall. He was elected an IEEE Fellow in 1992 for “leadership in and contributions to CMOS device and process technology.”
Chen holds a B.S. in E.E. from National Taiwan University, an M.S. in E.E. from University of Maine, a Ph.D. in E.E. from UCLA, and a Master degree from the UCLA Executive Engineering Management Program. He was a Technical Advisor for ITRI, Taiwan, and serves on boards in the industry.

June 4, 2012 — AKHAN Technologies Inc., advanced diamond electron device designer, will collaborate with the Center for Nanoscale Materials (CNM) at Argonne National Laboratory (Argonne Labs) to fully characterize Miraj Diamond devices and materials, which are made by doping n-type diamond and can be used in the semiconductor industry.
Through "Characterization of Novel N-type Nanocrystalline Diamond and Related Diode Devices," the team will better understand the electronic properties of n-type doped diamond thin films, using CNM’s various nanoscale characterization techniques. Results of these studies will be disseminated in a non-proprietary manner.
“Europe has been focused on the delta doping method, which has extremely narrow process requirements including the requirement of very thick diamond on expensive single-crystal diamond carriers, implemented commercially by companies like Element 6 De Beers. Japan has been forward looking, investing heavily in more cost-effective diamond-on-silicon microchip technology, [which is] useful only in very hot and otherwise extreme environments with epitaxial diamond-on-diamond wafers but not at all with diamond-on-silicon wafers, implemented by institutions like Japan’s National Institute of Science and Technology and Nippon” said Adam Khan, AKHAN founder and chief executive.
The n-type diamond material Miraj Diamond, developed in the US with the help of wafer fabs, enables highly manufacturable, fully functioning diamond microchips, Khan said. The Miraj Diamond platform enables fabrication of complex devices such as high speed/power transistors, RF, and microwave electronics.

AlN templates replace bare and patterned sapphire substrates for manufacturing blue, green, and white GaN light emitting diodes (LEDs).
LED manufacturers are transitioning from 2” to 6” wafers, Kyma Technologies reports. While 10” and 12” wafers remain primarily in demonstration phase today, LED makers will be moving to the larger wafer diameters in the next few years, the company predicts. Larger wafers produce more die per wafer, making tool utilization more efficient and achieving higher volume production.
Kyma has demonstrated 12” AlN-on-silicon (Si) templates that can be used for GaN growth. The company commissioned a high-volume PVDNC tool in early 2011 and has qualified customers on it for 2” processes, said Ed Preble, Kyma CTO.
