Title: David J Lischner: Innovator in Silicon Device Technology

Introduction

David J Lischner is a notable inventor based in Salisbury, PA (US). He has made significant contributions to the field of silicon device technology, holding 2 patents that showcase his innovative approaches.

Latest Patents

Lischner's latest patents include a "Method of making dielectrically isolated silicon devices" and a "Process for producing silicon devices." The first patent describes a technique for producing structures useful for dielectrically isolated high voltage devices. This method involves creating a cavity in a silicon wafer, oxidizing the surface to form a dielectric material, and depositing silicon onto this material. The entire region of polycrystalline silicon is then melted, resulting in a thick region of dielectrically isolated single crystal silicon, which is essential for high voltage devices. The second patent outlines a process for producing dielectrically isolated regions of single crystal silicon through a specific melting process. This involves treating a substrate with regions of single crystal silicon in contact with non-single crystal silicon overlying a dielectric material. The non-single crystal silicon is melted using radiant energy, and upon cooling, it converts into a region of single crystal material.
