摘要:
A method for making PMOS and NMOS transistors 60, 70 on a semiconductor substrate 20 that includes having a gate protection layer 210 over the gate electrode layer 110 during the formation of source/drain silicides 120. The method may include implanting dopants into a gate polysilicon layer 115 before forming the protection layer 215.
