By providing a gate dielectric material of increased thickness for P-channel transistors compared to N-channel transistors, degradation mechanisms, such as negative bias threshold voltage instability, hot carrier injection and the like, may be reduced. Due to the enhanced reliability of the P-channel transistors, overall production yield for a specified quality category may be increased, due to the possibility of selecting narrower guard bands for the semiconductor device under consideration.
