Gate structures
摘要:
An apparatus includes a first device. The first device includes a first projection and a first gate structure, the first projection extending upwardly from a substrate and having a first channel region therein, and the first gate structure engaging the first projection adjacent the first channel region. The first structure includes an opening over the first channel region, and a conformal, pure metal with a low resistivity disposed in the opening. The apparatus also includes a second device that includes a second projection and a second gate structure, the second projection extending upwardly from the substrate and having a second channel region therein, and the second gate structure engaging the second projection adjacent the second channel region. The second structure includes a silicide disposed over the second channel region, wherein the silicide includes a metal that is the same metal disposed in the opening.
