Sidewall process and method of implantation for improved CMOS with benefit of low CGD, improved doping profiles, and insensitivity to chemical processing

摘要

A transistor (30) and method for forming a transistor using an edge blocking material (24) is disclosed herein. The edge blocking material (24) may be located adjacent a gate (22) or disposable gate or may be part of a disposable gate. During an angled pocket implant, the edge blocking material (24) blocks some dopant from entering the semiconductor body (10) and the dopant (18) placed under the edge blocking material is located at a given distance below the surface of the semiconductor body (10).
