Fab 1 in Dresden, Germany, belonging to GlobalFoundries Inc. (Sunnyvale, Calif.), is starting work to help develop 22-nm CMOS process and will run the process in volume. It is not clear whether the 22-nm will include a departure from the gate-first high-K metal gate (HKMG) CMOS processes currently being brought up at 32- and 28-nanometers.
Fab 1 was expected to be workhorse fab at the 45/40-nm and 32/28-nm nodes while GlobalFoundries' wafer fab under construction in New York state, Fab 8, would run the 22-nm production and more advanced nodes.
"The 22-nm node is being worked on in Fab 1, and elsewhere. Fab 1 will pilot ramp and go to some volume in 22-nm," according to Udo Nothelfer, general manager of Fab 1. Nothelfer said that while GlobalFoundries was working quickly to erect its fab in New York, commercial production was not scheduled to start there before the second half of 2012 and that production of 22-nm CMOS would be required before that.
