Abstract:
A structure and method for fabricating silicide contacts for semiconductor devices is provided. Specifically, the structure and method involves utilizing chemical vapor deposition (CVD) and annealing to form silicide contacts of different shapes, selectively on regions of a semiconductor field effect transistor (FET), such as on source and drain regions. The shape of silicide contacts is a critical factor that can be manipulated to reduce contact resistance. Thus, the structure and method provide silicide contacts of different shapes with low contact resistance, wherein the silicide contacts also mitigate leakage current to enhance the utility and performance of FETs in low power applications.
