Abstract
A Schottky diode is adjusted by implanting an implant species by way of a titanium silicide Schottky contact and driving the implant species into the underlying silicon substrate by a rapid anneal. The implant is at a low energy, (e.g. about 10 keV) and at a low dose (e.g. less than about 9E12 atoms per cm) such that the barrier height is slightly increased and the leakage current reduced without forming pn junction and retaining the peak boron concentration in the titanium silicide layer.
