CENS reports Sun Microsystems will use TSMC's 40nm process technology for its upcoming Rainbow Falls processor family. Volume production of these chips will start sometime next year.
By wining a significant contract recently to build a family of server-used high-performance central processing units (CPUs) using 40-nanometer process technology for Sun Microsystems Inc., Taiwan Semiconductor Manufacturing Co. (TSMC) has eventually cracked CPU foundry market.
TSMC has long depended on non-CPUs foundry contracts for most of its revenue. According to industry watchers, Sun Microsystems has contracted TSMC to make its Rainbow Falls family of CPUs using 40nm process. The microprocessors are noted for their 16 cores per chip, along with extended, glueless node-to-node coherent interconnects.
