Abstract

A compact model based on the Lambert function is used to describe I-V-T characteristics of Schottky Barrier Diodes (SBDs) with gated-edge termination (GET) with either SiN or SiO/AlO as GET dielectric. Electrical parameters obtained from this model enable Schottky barrier height (SBH) assessment. It will be shown that fluctuations are about 17% in both cases. Similar interface state density (from ideality factor) is obtained which is consistent with previous work and validates this approach as an interesting method to model these GET-SBDs.
