Title: Bruce Laurence Colburn: Innovator in Silicon Technology
Introduction
Bruce Laurence Colburn is a notable inventor based in Vancouver, WA (US). He holds a total of 3 patents that contribute significantly to the field of silicon technology. His innovative approaches have enhanced the production processes of silicon crystals, making them more efficient and productive.
Latest Patents
Colburn's latest patents include an "Oscillating crucible for stabilization of Czochralski (CZ) silicon melt." This method stabilizes the CZ silicon melt by controlling the oscillation of the crucible rotation during the stabilization period. This technique reduces gas bubbles and unmelted polysilicon particles, thereby increasing the yield and productivity of CZ silicon crystal production. The crucible rotation follows an Oscillating Crucible Rotation (OCR) pattern or a saw tooth rotation pattern, which involves rapid oscillations between high and low rates of rotation prior to the growth of the CZ crystal ingot.
Another significant patent is the "Apparatus and method for determining an epitaxial layer thickness." This invention provides a method for determining the epitaxial layer thickness and transition width in epitaxial single crystal silicon wafers. The apparatus includes an isotopically enriched doped substrate, and the method utilizes Second Ion Mass Spectrometry (SIMS) to ascertain the epitaxial layer thickness and transition width.
