Abstract
Field Effect Transistors (FETs), Integrated Circuit (IC) chips including the FETs, and a method of forming the FETs and IC. FET locations and adjacent source/drain regions are defined on a semiconductor wafer, e.g., a silicon on insulator (SOI) wafer. Source/drains are formed in source/drains regions. A stopping layer is formed on source/drains. Contact spacers are formed above gates. Source/drain contacts are formed to the stopping layer, e.g., after converting the stopping layer to silicide. The contact spacers separate source/drain contacts from each other.
