摘要:
By performing a heat treatment on the basis of a hydrogen ambient, exposed silicon-containing surface portions may be reorganized prior to the formation of gate dielectric materials. Hence, the interface quality and the material characteristics of the gate dielectrics may be improved, thereby reducing negative bias temperature instability effects in highly scaled P-channel transistors.
