Abstract

A shallow n+ layer of implanted phosphorus was used to lower the barrier height of PtSinSi schottky diodes. The reduction of barrier height of the forward turn-on voltages from 400mV to 180mV of the forward was followed by implantation of phosphorus at 35KeV with an ion dose of 8.0x10**12 atoms/cm\ulcornerand was activated at 925\ulcorner for 30min in dry O2. The test result showed that, as the ion-implanted dose increased, the forward turn-on voltage and reverse breakdown voltage were linearly decreased, but the saturation current and ideality factor(n) were linearly increased.
