Abstract
Disclosed herein is a method for fabricating a metal oxide semiconductor field effect transistor having cobalt silicide. According to the method, there is first provided a semiconductor substrate having exposed silicon portions on the surface thereof. The exposed silicon is either single crystalline silicon or polycrystalline silicon, and may include junction regions in which N typed or P typed impurity such as arsenic, phosphorous, or boron is formed. Niobium and cobalt are sequentially deposited on the exposed silicon portions by electron-beam evaporation method. Afterwards, annealing step is performed to form a cobalt silicide film on the exposed silicon portions.
