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.

"CATRENE" program to lead EU micro/nano R&D beyond 2008

10/30/2007  October 30, 2007 - A new public/private R&D initiative is being laid out to replace the MEDEA+ program for cooperative R&D in microelectronics that is set to expire in 2008, which over the past seven years has watched over three generations of CMOS technology, and spearheaded work on fields ranging from smart cards, image sensors, and automotive electronics.

NAND flash, MPUs, foundry trends "shake up" 3Q07 chip supplier ranks

10/30/2007  October 30, 2007 - Demand for NAND flash memory, battles in the MPU space, and pains of big customers' change in strategies have shuffled the rankings of top chip suppliers in 3Q07, just as predicted, according to data from IC Insights.

Rexchip, Air Products ink gas supply deal

10/30/2007  October 30, 2007 - Air Products and its Taiwan subsidiary Air Products San Fu Co Ltd. have agreed to supply nitrogen and bulk gases for Taiwan DRAM producer Rexchip Semiconductor Corp., the Powerchip-Elpida memory JV. Financial details were not disclosed.

SIA: September chip sales surge with PC, phone push

10/29/2007  October 29, 2007 - Worldwide semiconductor sales rose ~5% for the second consecutive month to a record $22.60 billion in Sept. 2007, riding demand for PCs and cell phones as seasonal patterns build to a head, according to data from the SIA.

Moore's Law to head z-ward?

10/29/2007  While the industry struggles to continue on the Moore's Law track, 3D approaches superior to those of systems-on-chip may provide an interim solution if the shrink slows down. A SEMATECH-organized workshop in Albany, NY earlier this month (Oct. 11-12) addressed fundamental issues about 3D, including four reasons why every chipmaker has 3D/TSVapproaches on its roadmap, and what needs to be solved before 3D can be effective beyond simple memory.

Analyst: Chip tool market to rise modestly after 3Q trough
