ABSTRACT:
A semiconductor processing method of forming a conductive polysilicon line relative to a substrate includes, a) providing a line of silicon on a substrate, the line having an outer top surface and outwardly exposed opposing outer sidewall surfaces, the line ultimately comprising conductively doped polysilicon; b) masking the line outer top surface with a masking material; c) with the masking material in place, depositing a metal layer atop the substrate and over the masking material and the outwardly exposed line outer sidewall surfaces; d) annealing the line to impart a silicidation reaction between the metal and opposing silicon sidewalls to form opposing metal silicide runners extending along the line sidewalls, the masking material preventing a silicidation reaction from occurring between the metal and line outer top surface; and e) stripping the metal layer from atop the line. Such a line is preferably used as a bottom gate for a thin film transistor. The invention also includes conductive polysilicon lines and thin film transistors.
