LONDON – A 50-hectare (about 120 acres) plot of land is being appropriated by the Central Taiwan Science Park in Taichung, Taiwan, on which foundry Taiwan Semiconductor Manufacturing Co. Ltd. (TSMC) could build a 450-mm wafer fab, according a Taiwan Economic News report.
The report added that the projected cost of the 450-mm wafer fab would involve an investment exceeding NT800 billion (about $26 billion), or nearly three times the cost of TSMC's Fab 15 Gigafab currently being built on the science park.
The report referenced TSMC as saying Tuesday (Dec. 12) that the earliest it would start building the fab would be 2015 to 2016 but that once the 450-mm diameter wafer size becomes mainstream it planned to also build 450-mm wafer fabs in Hsinchu and Tainan.
TSMC is expected to bring up 450-mm wafer processing at two of its established wafer fabs, built for 300-mm wafer processing, before building a dedicated 450-mm wafer fab.
A 450-mm pilot line is expected to go into Fab 12 in Hsinchu, Taiwan and be running the 20-nm process technology node by 2013 to 2014. Following that TSMC plans to bring up 450-mm volume production within Fab 15 on the Central Taiwan Science Park in Taichung. This would process devices at the 14-nm node, the node at which TSMC is expected to switch from planar transistors in bulk CMOS to FinFET structures.http://cms.eetimes.com/ContentCreator/SelectContentItemType
rhusain, I agree sounds very high. Not sure how anyone will have the revenue stream to pay for a 26 billion dollar investment. I always heard you need ~3x the cost of the fab in revenue to justify it. Since the whole semi market market is currently 300 billion and leading edge process is only a fraction of that, hard to imagine how many of these fabs get built...
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
