Abstract:
1. A metal oxide semiconductor field effect transistor (MOSFET), device, comprising: a gate structure on an underlying gate insulator layer, wherein said gate structure is comprised of an underlying polysilicon shape recessed below the top surface of an insulator spacer, and comprised of an overlying, regrown polysilicon gate shape; an insulator spacer located only on the vertical sides of said gate structure; a lightly doped source/drain (LDD), region comprised with a first portion located under said insulator spacer, and comprised of a second portion of said LDD region located between said first portion of said LDD region and an adjacent heavily doped source/drain region; a heavily doped source/drain region in said semiconductor substrate, recessed below the top surface of said semiconductor substrate; a raised single crystalline silicon source/drain structure located on recesses, said heavily doped source/drain region and located on said second portion of said LDD region; and metal silicide shapes on said raised single crystalline silicon source/drain structure, and on said overlying, regrown polysilicon gate shape.
