摘要:
A method of forming a semiconductor device is provided. The method includes forming a recess in a substrate and forming a first dielectric layer in the recess. A portion of the first dielectric layer is removed. A second dielectric layer is formed over the first dielectric layer. A gate structure is formed over the second dielectric layer.
