Title: Edward J Rice: Innovator in Semiconductor Technology

Introduction

Edward J Rice is a notable inventor based in Los Gatos, California. He has made significant contributions to the field of semiconductor technology, holding a total of 5 patents. His work primarily focuses on the fabrication of advanced field-effect transistors, which are essential components in modern electronic devices.

Latest Patents

Among his latest patents is a method of fabricating a lateral FET structure that utilizes a substrate to source. This innovative MOS transistor is particularly suitable for use in the VHF and UHF regions. It features a common source lateral MOSFET formed on a substrate, which serves as the connection for the source to the header. The substrate, preferably P-type, has both P-type and N-type epitaxial regions, along with a sinker that connects the source to the substrate. The design includes a vertically isolated field-effect transistor with a drain positioned atop a mesa on the N-type epitaxial region. The gate overhangs the edge of a channel adjacent to the mesa, while the source is located at the lateral edges of the groove defining the mesa's edge. This process allows for simultaneous diffusion of the source and drain regions, followed by a metal masking step that effectively connects the source to the substrate.

Another significant patent involves the method of fabricating a mesa MOSFET using an overhang mask. This patent describes a mesa structure field-effect transistor that includes a semiconductor body with at least one mesa formed on its major surface. An insulating layer is placed on the mesa, overhanging it. Doped regions in the side walls of the mesa define the channel region and source of the transistor, while the semiconductor body defines the drain region. The use of preferential etching techniques is crucial in forming the mesas and the overhanging insulator, which acts as a shadow mask during fabrication.
