摘要:
Methods and associated structures of forming a microelectronic device are described. Those methods comprise providing a substrate comprising a first transistor structure comprising an n-type gate material and second transistor structure comprising a p-type gate material, selectively removing the n-type gate material to form a recess in the first gate structure, and then filling the recess with an n-type metal gate material.
