摘要: To improve performance of a semiconductor device. Over a semiconductor substrate, a plurality of p-channel type MISFETs for logic, a plurality of n-channel type MISFETs for logic, a plurality of p-channel type MISFETs for memory, and a plurality of n-channel type MISFETs for memory are mixedly mounted. At least a part of the p-channel type MISFETs for logic have each a source/drain region constituted by silicon-germanium, and all the n-channel type MISFETs for logic have each a source/drain region constituted by silicon. All the p-channel type MISFETs for memory have each a source/drain region constituted by silicon, and all the n-channel type MISFETs for memory have each a source/drain region constituted by silicon.
