Method for Forming Non-Amorphous, Ultra-Thin Semiconductor Devices Using Sacrificial Implantation Layer

摘要

A method for forming a semiconductor device includes defining a sacrificial layer (108) over a single crystalline substrate (106). The sacrificial layer (108) is implanted with a dopant species in a manner that prevents the single crystalline substrate (106) from becoming substantially amorphized. The sacrificial layer (108) is annealed so as to drive said dopant species from said sacrificial layer (108) into said single crystalline substrate (106).
