  • Improving the Way We Change Materials
    Laura Peters, Editor-in-Chief - 07/17/2008
    Patterning and new materials are probably the greatest grand challenges in semiconductor processing for the next 3-5 years, according to a panel at a Praxair event held Tuesday at SEMICON West. More

  • Funding for ISMI 450 mm Effort Doubling
    David Lammers, News Editor - 07/22/2008
    The large chip companies supporting the 450 mm wafer transition have put supplemental funding behind the 450 mm program at ISMI, said director Scott Kramer at SEMICON West. However, the large equipment vendors joined with SEMI officials to question the return on investment of the larger substrates. More
  • Molding Techniques Support Thin Gold Wires, Low-k Materials
    Kenji Tsuda, Asia Contributing Editor - 07/21/2008
    Competing Japan-based molding machine manufacturers have developed techniques that support the thinner packages required for cell phones. The new molding methods also ease the mechanical pressure placed on the relatively fragile low-k dielectric materials in leading-edge logic devices. More
  • Industry Veteran Receives Honor
    Craig Addison, Senior Editor, Communications, SEMI, San Jose - 07/16/2008
    The 2008 Karel Urbanek Memorial Award was presented to Paul Langer of Komatsu Silicon America for contributions over 40 years to the development of silicon material standards. More
  • Soitec Ready With Ultrathin SOI Wafers
    David Lammers, News Editor - 07/16/2008
    In a materials advance that could enable multi-gate logic devices and floating body single transistor memories, Soitec said it has qualified a line of SOI wafers that feature ultrathin top silicon and buried oxide (BOX) layers. More
  • When Will 450 mm Make Economic Sense?
    Jonathan Davis, Executive Vice President, Global Expositions, Marketing, Communications and EHS, SEMI, San Jose - 07/15/2008
    There is an industry-wide curiosity about the reality behind a wafer size transition to 450 mm. According to the International Technology Roadmap for Semiconductors (ITRS), this transition should happen in 2012 to keep the industry on Moore’s Law, and a few companies are pushing hard to make this happen.

  • Intermolecular Speeds R&D for Elpida’s Next-Gen Memory
    Aaron Hand, Executive Editor, Electronic Media - 07/15/2008
    Intermolecular Inc. (San Jose) today announced a new collaborative development program (CDP) and licensing agreement with Elpida Memory Inc. (Tokyo) to enable rapid development of new materials and process technologies for Elpida’s next-generation memory chips. More
  • ISMI to Report 450 mm Progress at West
    David Lammers, News Editor - 07/10/2008
    ISMI will present data gathered from 450 mm test wafers to several SEMI task forces at next week’s SEMICON West conference in San Francisco. ISMI Director Scott Kramer said, “This is our fundamental strategy: We are gathering data, doing testing, to influence the standards.” ISMI managers will also present progress on the 300 mm Next Generation Factory initiative.

    Intel’s Gargini: Semi equipment makers overestimating cost of moving to 450-mm wafers
By Ann Steffora Mutschler, Senior Editor, 06/13/2008
The move to the 450-mm wafer size has garnered an increasing amount of interest in the semiconductor manufacturing industry as many suppliers have pushed back at making the shift, arguing that there is still much to be gained in terms of efficiency from the 300-mm wafer size and noting high development costs. But with regard to the move to the 450-mm wafer size, “from a technical point of view, this is not really very difficult,” Intel Fellow Paolo Gargini says....
