High performance 25 nm gate CMOSFETs for 65 nm node high speed MPUs
K. Goto,Y. Tagawa,Hiroyuki Ohta,Hiroshi Morioka,Sergey Pidin,Y. Momiyama,H. Kokura,S. Inagaki,Naoyoshi Tamura,Mitsuaki Hori,Toshihiko Mori,Masataka Kase,K. Hashimoto,Manabu Kojima,Toshihiro Sugii +14 more
TL;DR: In this article, a 25 nm gate CMOSFET for the 65 nm node is reported, where the authors successfully improved the short channel effect while keeping a high drive current by using total process controls (SW, offset-spacer, extension, halo, mechanical stress, etc) both mobility in nMOS and NBTI in pMOS are improved by combination of low temperature annealing and oxynitride gate oxide with low nitrogen concentration.
