Title: Walter E. Gaida: Innovator in Silicon Technology

Introduction

Walter E. Gaida is a notable inventor based in East Pittsburgh, PA (US). He has made significant contributions to the field of silicon technology, holding a total of 5 patents. His work primarily focuses on advanced methods for growing high-purity silicon and silicon carbide crystals.

Latest Patents

One of Gaida's latest patents is an advanced physical vapor transport method and apparatus for growing high-purity silicon feedstock. In this innovative process, silicon is melted and vaporized in a physical vapor transport furnace. The vaporized silicon is then reacted with a high-purity carbon member, such as a porous carbon disc, which is positioned directly above the silicon. The gaseous species resulting from this reaction are deposited on a silicon carbide seed crystal located above the disc, facilitating the growth of monocrystalline silicon carbide. Additionally, in another embodiment, various gases, including carbon-containing gases, can be introduced into the furnace to enhance the growth process.
