    摘要: A method for forming a semiconductor structure includes providing a substrate comprising a first device region, forming a metal-oxide-semiconductor (MOS) device in the first device region, forming a stressed layer over the MOS device, and performing a post-treatment to modulate a stress of the stressed layer. The post-treatment is selected from the group consisting essentially of ultra-violet (UV) curing, laser curing, e-Beam curing, and combinations thereof.
