摘要:
A field effect transistor device includes a first gate stack portion including a dielectric layer disposed on a substrate, a first TiN layer disposed on the dielectric layer, a metallic layer disposed on the dielectric layer, and a second TiN layer disposed on the metallic layer, a first source region disposed adjacent to the first gate stack portion, and a first drain region disposed adjacent to the first gate stack portion.
