Abstract:

The present invention provides a complementary metal oxide semiconductor integration process whereby a plurality of silicided metal gates are fabricated atop a gate dielectric. Each silicided metal gate that is formed using the integration scheme of the present invention has the same silicide metal phase and substantially the same height, regardless of the dimension of the silicide metal gate. The present invention also provides various methods of forming a CMOS structure having silicided contacts in which the polySi gate heights are substantially the same across the entire surface of a semiconductor structure.

Abstract(Chinese):

本发明提供了一种互补金属氧化物半导体集成工艺，其中在栅极电介质顶部制造多个硅化金属栅极。使用本发明的集成方案形成的每个硅化金属栅极与硅化物金属栅极的尺寸无关，具有相同的硅化物金属相和基本上相同的高度。本发明还提供了形成具有硅化物触点的CMOS结构的各种方法，其中多晶硅栅极高度在半导体结构的整个表面上基本相同。
