Abstract:
An improved process for implanting the exposed portions of a surface of a silicon substrate and the surface of a polysilicon gate electrode to amorphize such silicon to permit the subsequent formation of metal silicide having smaller grain size than metal silicide formed from non-amorphized silicon, the improvement comprising:a) orienting said silicon substrate to an implantation beam so that the axis of said implantation beam defines an angle ranging from about 15.degree. to about 60.degree. with a line perpendicular to the plane of said surface of said substrate; andb) implanting said exposed portions of said surface of said silicon substrate and said polysilicon gate electrode surface with said implantation beam to amorphize said silicon surfaces while maintaining said tilt angle between the axis of said implantation beam and said line perpendicular to said plane of said surface of said silicon substrate.
