Patent ID: 8648412

Claim:
A method of forming a semiconductor device comprising the acts of: providing a region of semiconductor material of a first conductivity type having a first major surface; forming a trench in the region of semiconductor material extending from the first major surface; forming an insulator layer adjacent sidewall surfaces of the trench; forming a control electrode in the trench and overlying a portion of the insulator layer; forming a body region of a second conductivity type within the region of semiconductor material, wherein the control electrode is configured to control a channel in the body region; forming a source region within the body region; forming a body contact structure extending from the major surface; forming an amorphized body region within the body region and connected to the body contact structure, wherein the act of forming the amorphized body region comprises a first ion implantation; forming a body contact region of a second conductivity type within the amorphized body region, wherein the act of forming the body contact region comprises a second ion implantation; annealing the body contact region; and forming a conductive region within the body contact structure extending from the major surface and contacting the body contact region.
