Abstract

The present disclosure relates to semiconductor devices and a process sequence in which a semiconductor alloy, such as silicon/germanium, may be formed in an early manufacturing stage, wherein other performance-increasing mechanisms, such as a recessed drain and source configuration, possibly in combination with high-k dielectrics and metal gates, may be incorporated in an efficient manner while still maintaining a high degree of compatibility with conventional process techniques.
