Abstract:
A semiconductor device is provided. The semiconductor device includes a channel region disposed between a source region and a drain region, a gate structure over the channel region, an interlayer dielectric (ILD) layer proximate the gate structure, an ILD stress layer proximate the top portion of gate structure and over the ILD layer. The gate structure includes a first sidewall, a second sidewall and a top portion. A first stress memorization region is also provided. The first stress memorization region is proximate the top portion of the gate structure. A method of making a semiconductor device is also provided.
