Abstract:
The present application provides a static random access memory (SRAM) cell. In one embodiment, the SRAM cell includes a first pass-gate field effect transistor (FET) and a first pull-up FET formed over at least one SiGe fin in a first N-type well (N-well) region; a second pass-gate FET and a second pull-up FET formed over at least one SiGe fin in a second N-well region; a first pull-down FET formed over one of a plurality of Si fins in a P-type well (P-well) region between the first and second N-well regions; and a second pull-down FET formed over another of the plurality of Si fins in the P-well region. Channel regions and source/drain regions of the first and second pass-gate FETs and the first and second pull-up FETs include SiGe alloys of different compositions or different impurity doping levels.

Claim (Index 1):
A Static Random Access Memory (SRAM) cell comprising:\n a P-type well (P-well) region; a first N-type well (N-well) region and a second N-well region on opposite sides of the P-well region; a plurality of Si fins in the P-well region; at least one SiGe fin in the first N-well region; at least one SiGe fin in the second N-well region; a first pass-gate field effect transistor (FET) and a first pull-up FET formed over the at least one SiGe fin in the first N-well region; a second pass-gate FET and a second pull-up FET formed over the at least one SiGe fin in the second N-well region; a first pull-down FET formed over one of the plurality of Si fins in the P-well region; and a second pull-down FET formed over another of the plurality of Si fins in the P-well region, wherein channel regions of the first and second pass-gate FETs and the first and second pull-up FETs include first SiGe alloy, and source/drain regions of the first and second pass-gate FETs and the first and second pull-up FETs include second SiGe alloy, wherein the first SiGe alloy is different from the second SiGe alloy in composition or impurity doping.
