Abstract:
Semiconductor structures are provided. The semiconductor structure includes a base including first, second, third, and fourth regions, used for first, second, third, and fourth transistors, respectively. A gate dielectric layer is on the first, second, third and fourth regions of the base. A first material layer is on the gate dielectric layer. A second material layer is on the first material layer above the fourth region. A third material layer is on the first material layer above the third region and on the second material layer above the fourth region. A fourth material layer is on the third material layer above the third and fourth regions and on the first material layer on the second region. The first material layer above the first region is used as a first work function layer for the first transistor.
