Abstract

Official abstract text for this publication.

A method of manufacturing a semiconductor device includes forming devices including source, drain and gate electrodes on a front surface of a substrate including a bulk silicon, a buried oxide layer, an active silicon, a gallium nitride layer, and an aluminum-gallium nitride layer sequentially stacked, etching a back surface of the substrate to form a via-hole penetrating the substrate and exposing a bottom surface of the source electrode, conformally forming a ground interconnection on the back surface of the substrate having the via-hole, forming a protecting layer on the front surface of the substrate, and cutting the substrate to separate the devices from each other.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of manufacturing a semiconductor device, the method comprising: forming devices on a front surface of a substrate, each of the devices including a source electrode, a drain electrode, and a gate electrode, and the substrate including a bulk silicon, a buried oxide layer, an active silicon, a gallium nitride layer, and an aluminum-gallium nitride layer which are sequentially stacked; forming a via-hole penetrating the substrate by etching a back su…
