Introduction

David Kapolnek, an esteemed inventor based in Santa Barbara, CA, has made significant contributions to the field of semiconductor technology. With two patents to his name, his innovative work focuses on enhancing the performance and durability of semiconductor materials and devices.

Latest Patents

Kapolnek's latest patents revolve around the "Fabrication of semiconductor materials and devices with controlled electrical conductivity." He describes a method for protecting the surface of semiconductor materials from damage and dopant passivation. This process involves depositing a barrier layer of dense or reactive material on the semiconductor material shortly after its growth, using Metal-Organic Chemical Vapor Deposition (MOCVD) source gases. The barrier layer effectively blocks the diffusion of hydrogen into the material. Furthermore, the reactor can be cooled in a reactive or non-reactive gas ambience, allowing for the safe removal of the semiconductor material with minimal passivation of the dopant species. The barrier layer can be removed through various etching processes or can remain for ongoing surface protection. This layer also serves as a gettering mechanism, chemically binding any hydrogen trapped in the semiconductor and preventing its diffusion.
