Abstract
Performance of P-channel transistors may be enhanced on the basis of an embedded strain-inducing semiconductor alloy by forming a gate electrode structure on the basis of a high-k dielectric material in combination with a metal-containing cap layer in order to obtain an undercut configuration of the gate electrode structure. Consequently, the strain-inducing semiconductor alloy may be formed on the basis of a sidewall spacer of minimum thickness in order to position the strain-inducing semiconductor material closer to a central area of the channel region.
