Title: The Innovations of Charles R. Snider: A Pioneer in Gallium Arsenide Technologies

Introduction: Charles R. Snider, an accomplished inventor based in Southboro, MA, has made significant contributions to the field of semiconductor technology. With a total of two patents to his name, Snider's work has paved the way for advancements in the fabrication of gallium arsenide devices, enhancing their performance and reliability.

Latest Patents: Snider's latest innovations include two notable patents that reflect his expertise in selective epitaxial growth processes. The first patent, titled "Selective epitaxial growth of gallium arsenide with selective orientation," describes a method for fabricating semiconductor devices on semi-insulating GaAs substrates. This method employs pre-etched holes in the substrate, which are covered by a dielectric layer. The dielectric is then selectively etched to expose only the bottoms of these holes, facilitating epitaxial growth of gallium arsenide in a single crystallographic orientation. This approach effectively minimizes random growth, resulting in improved surface morphology in the active areas.

The second patent, "Selective epitaxial etch planar processing for gallium arsenide," details a technique for fabricating gallium arsenide circuits or devices using vapor phase epitaxy. In this method, source and drain contact areas are deposited through holes in a refractory mask. After selectively etching portions of the mask, holes are created using chemical or plasma etching, allowing highly doped gallium arsenide to be grown epitaxially, thus defining drain and source regions. The process culminates in a single step of metallization and lift-off to establish connections to the gate, drain, and source regions on a planar surface.
