Title: The Innovations of David W. Keck

Introduction

David W. Keck is a notable inventor based in Butte, MT (US), recognized for his contributions to the field of semiconductor technology. He holds a total of 6 patents, showcasing his innovative spirit and technical expertise. His work primarily focuses on the production of high-purity polycrystalline silicon rods, which are essential for various semiconductor applications.

Latest Patents

One of his latest patents is a "Chemical vapor deposition system for polycrystalline silicon rod production." This invention discloses processes and reactor apparatus designed for the rapid production of large diameter, high-purity polycrystalline silicon rods. The system utilizes A.C. current, with a fixed or variable high frequency ranging from about 2 kHz to 800 kHz, to concentrate at least 70% of the current in an annular region that constitutes the outer 15% of a growing rod, leveraging the "skin effect."

Another significant patent is the "Method for inducing controlled cleavage of polycrystalline silicon rod." This method addresses the challenges associated with unwanted cracks and spalls during the growth of polycrystalline silicon rods. By inducing a flaw in a filament on which silicon is deposited, the rod is designed to break in a controlled manner at a desired location, thereby improving the yield of the rod growing process and minimizing usable rod length losses due to spalling.
