Abstract:
1. A method of forming a metal oxide semiconductor effect transistor (MOSFET) on a semiconductor substrate, comprising the steps of: forming a silicon dioxide gate insulator layer on said semiconductor substrate; performing a plasma nitridation procedure on the silicon dioxide gate insulator layer to form a nitrided gate insulator layer; performing a hydrogen anneal procedure on the nitrided gate insulator layer; forming a conductive gate structure on a portion of said nitrided gate insulator layer; forming a lightly doped source/drain region in an area of said semiconductor substrate not covered by said conductive gate structure; forming insulator spacers on sides of said conductive gate structure; and forming a heavily doped source/drain region in an area of said semiconductor not covered by said conductive gate structure or by said insulator spacers.
