    Abstract: Disclosed is a semiconductor device having a p-n junction with reduced junction leakage in the presence of metal silicide defects that extend to the junction and a method of forming the device. Specifically, a semiconductor layer having a p-n junction is formed. A metal silicide layer is formed on the semiconductor layer and a dopant is implanted into the metal silicide layer. An anneal process is performed causing the dopant to migrate toward the metal silicide-semiconductor layer interface such that the peak concentration of the dopant will be within a portion of the metal silicide layer bordering the metal silicide-semiconductor layer interface and encompassing the defects. As a result, the silicide to silicon contact is effectively engineered to increase the Schottky barrier height at the defect, which in turn drastically reduces any leakage that would otherwise occur, when the p-n junction is in reverse polarity.

    Abstract: A fabrication method for a semiconductor device structure is provided. The device structure has a layer of silicon and a layer of silicon dioxide overlying the layer of silicon, and the method begins by forming an isolation recess by removing a portion of the silicon dioxide and a portion of the silicon. The isolation recess is filled with stress-inducing silicon nitride and, thereafter, the silicon dioxide is removed such that the stress-inducing silicon nitride protrudes above the silicon. Next, the exposed silicon is thermally oxidized to form silicon dioxide hardmask material overlying the silicon. Thereafter, a first portion of the silicon dioxide hardmask material is removed to reveal an accessible surface of the silicon, while leaving a second portion of the silicon dioxide hardmask material intact. Next, silicon germanium is epitaxially grown from the accessible surface of the silicon.
