ABSTRACT:
A semiconductor device structure is described, including a MOS transistor, a silicon-rich silicon nitride layer having a refractive index of about 2.00-2.30, and a dielectric layer. The silicon-rich silicon nitride layer is disposed between the MOS transistor and the dielectric layer, and covers the source/drain region, the spacer and the gate conductor of the MOS transistor.
