  • Method of forming a polycide gate of a semiconductor device
    Patent number: 5908791
    Abstract: A method of forming a polycide gate of a semiconductor device, including the steps of etching all the metal silicide layer by using a plasma, and etching the polysilicon layer by relatively decreasing power for increasing the energy of a particles constituting the plasma, as compared with that in the step of etching the metal silicide layer. A physically and functionally stable polycide gate can be simply and rapidly formed.
