What's really behind the top foundries' 2008 capex cutbacks?

11/06/2007  After forecasting good to "lackluster" 4Q sales forecasts, the top pure-play foundries (TSMC, UMC, SMIC, and Chartered) say they will reduce spending in 2008, (10%-25% declines or more). Their stated reasons -- improve productivity in current production, migrate more mature processes down to 90nm and 65nm, and get ASPs back up and improve profitability -- send a great message to the investor community. But the real reason could be a much bigger shift in the leading-edge foundry business model.

Productronica 2007 Preview

11/05/2007  Things just keep getting smaller. Two years ago at Productronica 2005, MicroNanoWorld was launched to address the increasing importance of micro-electronics production. It was continued at Electronica 2006, which alternates bi-annually with Productronica. This year, micro-electronics production is set to take center stage, as "Productronica 2007: Micro-Production in the Limelight" gets under way from November 13-16, 2007 at New Munich Trade Fair Center, Munich, Germany.

Tackling systematic/random variations while matching process chambers

11/05/2007  Few fab management practices are more "in the trenches" than using mathematics and statistics to investigate and solve real-life problems. One such technique highlighted at the recent ISMI Symposium on Manufacturing Effectiveness was "multivariate analysis" -- specifically, comparing two ashing chambers that were supposed to be matched, but whose output showed differences.

STMicro starts building China backend site

11/05/2007  November 5, 2007 - STMicroelectronics has begun construction at a new packaging/text facility in Longgang, Guangdong Province, China.
