  • Patent number: 5989987
    Abstract: A method is provided for use in semiconductor fabrications to form a self-aligned contact (SAC) in a semiconductor device, which can help increase the contact area between the metallization layer and the substrate and also prevent the occurrence of a short-circuit between the metallization layer and a conductive layer, such as a tungsten silicide layer, in the gate structures. In particular, the method utilizes an etchant that can etch into the tungsten silicide much more effectively than into the overlying silicon nitride layer and the underlying polysilicon layer. The constricted shape can better prevent the silicide layer from coming into contact, and thus forming a short-circuit, with the subsequently formed metallization layer. Moreover, since the silicide layer is reduced in size due the constriction, the underlying polysilicon layer can be correspondingly made smaller, allowing the contact area between the metallization layer and the substrate to be increased.
