摘要:
A method for fabricating a semiconductor device includes the steps of forming a metal gate on a substrate, a spacer around the metal gate, and a first interlayer dielectric (ILD) layer around the spacer, performing a plasma treatment process to transform the spacer into a first bottom portion and a first top portion, performing a cleaning process to remove the first top portion, and forming a second ILD layer on the metal gate and the first ILD layer.
