High Performance Devices and High Density Devices on Single Chip
摘要:
A CMOS chip comprising a high performance device region and a high density device region includes a plurality of high performance devices comprising n-type field effect transistors (NFETs) and p-type field effect transistors (PFETs) in the high performance device region, wherein the high performance devices have a high performance pitch; and a plurality of high density devices comprising NFETs and PFETs in the high density device region, wherein the high density devices have a high density pitch, and wherein the high performance pitch is about 2 to 3 times the high density pitch; wherein the high performance device region comprises doped source and drain regions, NFET gate regions having an elevated stress induced using stress memorization technique (SMT), gate silicide and source/drain silicide regions, and a dual stressed liner, and wherein the high density device region comprises doped source and drain regions, gate silicide regions, and a neutral stressed liner.
