摘要:
An integrated circuit comprises at least one block comprising a first cell and a second cell. The first cell comprises a first FET formed with a first contacted poly pitch (CPP), and the second cell comprises a second FET formed with a second CPP. The first CPP is greater than the second CPP. The first FET is part of a critical-speed path, and the second FET is part of a noncritical-speed path, in which the critical-speed path operates at a faster speed than the noncritical-speed path. The first FET and the second FET each comprise a planar FET, a finFET, a gate-all-around FET or a nanosheet FET. A method for forming the integrated circuit is also disclosed.
