Title: Method of fabricating source/drain region
Inventor: WANG TZU-YU
IPC: H01L21/28
Filed: 2003-10-16
Granted: 2004-08-11
Abstract: A method of fabricating a source/drain region is described. A first patterned material layer is formed on a substrate to expose a portion of the substrate. A chemical vapor deposition process is performed to form a conformal second material layer on the surfaces of the substrate and the first material layer. A first ion implantation process is performed to form a deeply doped region in the substrate by using the second material layer as an implantation mask. After removing the second material layer, a second ion implantation process is performed to form a shallow doped region at two sides of the deeply doped region by using the first material layer as an implantation mask. Since the source/drain region is composed of the deeply doped region and the shallow doped region, the resistance of the source/drain region can be reduced, and punch-through between adjacent the source region and the drain region can also be prevented.
