Title: Innovations of Marc H Vandenberg

Introduction

Marc H Vandenberg is a notable inventor based in Bend, OR (US). He has made significant contributions to the field of semiconductor technology, particularly in the development of power MOSFET devices. With a total of 4 patents to his name, Vandenberg's work has had a considerable impact on the industry.

Latest Patents

One of his latest patents is the "Low loss SiC MOSFET," which describes a Vertical Multiple Implanted Silicon Carbide Power MOSFET (VMIMOSFET). This innovative device includes a first conductivity semiconductor substrate and a first conductivity semiconductor drift layer on top of the substrate. It features a multitude of second conductivity layers implanted in the drift layer, with a body layer where the channel is formed. The design incorporates a first conductivity source layer interspaced appropriately within the second conductivity layers. Additionally, it includes a gate oxide of a specific thickness and another oxide of greater thickness, strategically placed to avoid distorting the gate oxide in the channel. This invention aims to deliver a power SiC MOSFET with increased frequency of operation and reduced switching losses.

Another significant patent is the "Pseudo self aligned radhard MOSFET and process of manufacture." This patent describes a Vertical Power MOSFET (VDMOS) device designed to withstand harsh radiation environments. The process of making such a device is also detailed. All implanted and diffused layers are 'self aligned' to a 'Sacrificial Poly' layer, which is later removed to prepare the wafers for a "late gate" oxide to be grown. The starting material with a graded doping profile in the epitaxial layer on the substrate enhances the SEB capability of the Power MOSFET.
