“Best of West” Award Finalists Announced

June 17th, 2009

SAN JOSE, Calif. – June 17, 2009– SEMI today announced the finalists for the 2009 “Best of West” awards, recognizing important product and technology developments in the microelectronics supply chain. Conducted in conjunction with SEMICON West, the largest and most influential microelectronics exposition in North America, the Best of West finalists have been selected based on their financial impact on the industry, engineering or scientific achievement, and/or societal impact.

The 2009 Best of West Finalists are:

  • AquiVia, from Alchimer. AquiVia is a new high-performance deposition technology that
    offers a substantially lower cost of ownership than alternative dry processes.
    Encompassing the three distinct process steps required before a through silicon via
    (TSV) can be filled with metal, it enables wet-process deposition of insulator, barrier and
    copper seed layers within high-aspect ratio TSVs using electrografting technology. This
    innovative approach ensures strong adhesion between all layers, and provides high yield
    and device reliability.
  • Stress-induced LIft-off Method, or SLIM-Cut, The SLIM-Cut method, developed by
    IMEC, addresses one of the biggest challenges of crystalline-Si for photovoltaics: kerffree
    wafering of substrates as thin as 50 microns. Fully based on mechanical stress, it is
    compatible with low-cost fabrication methods. Made of single crystalline material, the
    wafers have the potential to provide high-efficiency solar cells.
  • K-Patents Semicon Refractometer PR-33-S, from K-Patents, is a Digital Refractive
    Index (RI) measurement technology that offers many possibilities to increase wafer
    throughput and to cut down the chemical costs in the whole process from chemical
    supplies down to fab in-line and tool in-situ chemical concentration control.
  • CCS-1000 Critical Cleaning System by Nano Green Technology Inc., combines
    deionized (DI) water and ammonia gas (NH3) to form molecules that move in a pattern
    with well-defined relative phases—known as “coherent” water—developed and
    trademarked by NGT as ionized molecularly activated coherent solution—or iMACSTM—a
    revolutionary green, renewable, cleaning process solution—for the semiconductor, Flat
    Panel Display (FPD), Liquid Crystal Display (LCD), and data storage disk drive (DSDD)

    iMACS achieves an unmatched cleaning performance that removes nano particles—
    ionic, organic, or metallic—and provides a green—and safe—environment—without any
    waste. In the traditional SC-1 cleaning method, expensive chemicals etched and
    damaged devices and topography; with iMACS, the use of expensive chemicals is
    eliminated and operation costs are reduced—drastically.

  • Gore® Filters for Semiconductor Applications, from W.L. Gore & Associates, Inc.,
    GORE® Filters for Semiconductor Applications are 20-nm- to 100-nm-rated cartridge
    filters for chemicals, dilute chemicals and ultrapure water in wet process tools. These
    filters incorporate a new high flow ePTFE (expanded polytetrafluoroethylene) filtration
    media that allows a drop-in retention upgrade from 100 nm to 30 nm, enabling cleaner
    recirculation baths and reduced processing times.

The selection of finalists was made by a prestigious panel of judges representing a broad
spectrum of the microelectronics industry (a list of judges can be found at:

SEMICON West on July 15, 2009.
