Title: Bruce Gehman: Innovator in Sputtering Technology
Introduction
Bruce Gehman is a notable inventor based in Morgan Hill, CA (US). He has made significant contributions to the field of materials science, particularly in the development of advanced sputtering targets. With a total of 5 patents, his work has had a considerable impact on various applications in technology and manufacturing.
Latest Patents
One of Bruce Gehman's latest patents is a method of preparing an indium oxide/tin oxide target for cathodic sputtering. This innovative process involves subjecting an indium oxide/tin oxide powder with 5-15 wt. % tin oxide to an annealing treatment at temperatures exceeding 1,000 °C. The powder is then partially reduced and subjected to hot isostatic pressing, resulting in a sputtering target with a density of at least 95% of the theoretical density and a thermal conductivity of at least 14 Wm,K.
Another significant patent is for a cobalt base alloy target designed for a magnetron cathode sputtering system. This target is made from a cobalt base alloy that includes additional elements in specific concentrations, allowing for the formation of intermetallic phases. These phases are observed based on the phase diagram in equilibrium at the target's operating temperature. The target's microstructure is enhanced through heat treatment, which promotes the formation of intermetallic phases that are largely absent in the cast state.
