    Abstract: PROBLEM TO BE SOLVED: To provide a CMOS circuit which includes an n-FET gate stack having a gate dielectric and a metal gate conductor, and a p-FET gate stack having a gate dielectric layer and a silicon-containing gate conductor. SOLUTION: In the high-performance complementary metal oxide film semiconductor (CMOS) circuit, each semiconductor unit has at least the first gate stack and the second gate stack. The first gate stack is disposed on a first device region (e.g., n-FET device region) in a semiconductor board, and at least includes a gate dielectric layer 14, a metal gate conductor 16, and a silicon-containing gate conductor 18 that are laminated in increasing order. The second gate stack is disposed on a second device region (e.g., p-FET device region) in the semiconductor board; and at least includes a gate dielectric layer, and a silicon-containing gate conductor that are laminated in increasing order. The first and second gate stacks can be formed on the semiconductor board by a variety of integrated methods. COPYRIGHT: (C)2007,JPO&INPIT
