Abstract

Official abstract text for this publication.

An electronic device can include a semiconductor layer having a primary surface, and a Schottky contact comprising a metal-containing member in contact with a horizontally-oriented lightly doped region within the semiconductor layer and lying adjacent to the primary surface. In an embodiment, the metal-containing member lies within a recess in the semiconductor layer and contacts the horizontally-oriented lightly doped region along a sidewall of the recess. In other embodiment, the Schottky contact may not be formed within a recess, and a doped region may be formed within the semiconductor layer under the horizontally-oriented lightly doped region and have a conductivity type opposite the horizontally-oriented lightly doped region. The Schottky contacts can be used in conjunction with power transistors in a switching circuit, such as a high-frequency voltage regulator.

First claim

Opening claim text (preview).

What is claimed is: 1. An electronic device comprising: a first semiconductor layer having a first primary surface; a first power transistor comprising a gate electrode and a drain region that includes a horizontally-oriented lightly doped region within the first semiconductor layer and lying adjacent to the first primary surface; a Schottky contact comprising a first metal-containing member in contact with the horizontally-oriented lightly doped region; and a conductive ele…
