Abstract
A semiconductor device includes a wafer having a bulk layer and a III-V buffer layer on an upper surface of the bulk layer. The semiconductor device further includes at least one semiconductor fin on the III-V buffer layer. The semiconductor fin includes a III-V channel portion. Either the wafer or the semiconductor fin includes an oxidized III-V portion interposed between the III-V channel portion and the III-V buffer layer to prevent current leakage to the bulk layer.
