Title: Herbert Paul Maruska: Innovator in AlGaN Wafer Technology

Introduction

Herbert Paul Maruska is a notable inventor based in Winter Springs, FL (US). He has made significant contributions to the field of semiconductor technology, particularly in the development of aluminum gallium nitride (AlGaN) wafers. With a total of 3 patents to his name, Maruska's work has advanced the capabilities of high-quality crystal growth.

Latest Patents

Maruska's latest patents include a method for making free-standing AlGaN wafers. This innovative method involves forming a single crystal AlGaN layer directly on a single crystal LiAlO substrate using aluminum and gallium halide reactant gases. The process allows for the removal of the LiAlO substrate, resulting in a free-standing, single crystal AlGaN wafer. The growth of the AlGaN layer is achieved through vapor phase epitaxy (VPE), which provides commercially acceptable rapid growth rates. Notably, the AlGaN layer produced is devoid of carbon and exhibits a defect density of less than about 10 cm.
