Introduction

Charles Curtis Burkhart is an accomplished inventor based in Vancouver, WA (US). He is known for his significant contributions to the field of silicon crystal production. His innovative approach has led to advancements that enhance the efficiency and yield of Czochralski (CZ) silicon crystal growth.

Latest Patents

Burkhart holds a patent for 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. The technique aims to reduce gas bubbles and unmelted polysilicon particles, ultimately increasing the yield and productivity of CZ silicon crystal production. The crucible rotation is designed to follow an Oscillating Crucible Rotation (OCR) pattern or a saw tooth rotation pattern, which includes rapid oscillations between high and low rates of rotation prior to the growth of the CZ crystal ingot.
