摘要: A method for fabricating a semiconductor device is provided, which includes forming a screen layer on a substrate, the screen layer including a first portion doped with a first type impurity, forming a first undoped semiconductor layer on the screen layer, forming a gate structure on the first semiconductor layer, forming a first amorphous region on both sides of the gate structure in the first semiconductor layer, and re-crystallizing the first amorphous region through performing a first heat treatment of the first amorphous region.
