Abstract
A semiconductor device includes first and second n-type transistors and first and second p-type transistors. The first n-type transistor includes a first channel layer and a first portion of a high-k dielectric layer over the first channel layer. The second n-type transistor includes a second channel layer and a second portion of the high-k dielectric layer over the second channel layer, wherein the second portion includes a higher amount of an n-type dipole material than the first portion. The first p-type transistor includes a third channel layer and a third portion of the high-k dielectric layer over the third channel layer. The second p-type transistor includes a fourth channel layer and a fourth portion of the high-k dielectric layer over the fourth channel layer, wherein the fourth portion includes a higher amount of a p-type dipole material than the third portion.
