摘要:
A process for forming a shallow, lightly doped region in a semiconductor device. The method comprises the steps of providing a semiconductor substrate having a surface; growing an oxide layer on the substrate, the oxide having a thickness; depositing a layer of polysilicon on the oxide; patterning the polysilicon layer and the oxide layer to provide a gate structure; and implanting into the substrate a source and a drain region about the gate structure at an angle less than 90 degrees with respect to the surface of the substrate.
