Title: The Innovations of Carlton Wells
Introduction
Carlton Wells is a notable inventor based in San Luis Obispo, California. He has made significant contributions to the field of technology, particularly in the area of wafer carriers used in chemical mechanical planarization (CMP). With a total of three patents to his name, Wells has demonstrated a commitment to advancing the efficiency and effectiveness of semiconductor manufacturing processes.
Latest Patents
One of Carlton Wells' latest patents is a wafer carrier with a pressurized membrane and retaining ring actuator. This innovative design allows for precise control of downward force and edge effect during CMP. The retaining ring actuator is strategically placed within the retaining ring to manage its height relative to the bottom surface of the wafer carrier. An inflatable membrane is integrated across the bottom surface of the wafer carrier, enabling independent regulation of pressure in the bladder to control the downward force acting on the wafer during CMP. Additionally, an edge control bladder can be included within the carrier, allowing for adjustments in the force applied to the edge of the wafer. By managing the pressures of the retaining ring actuator, inflatable membrane, and edge control bladder, Wells' invention addresses non-uniformities in the wafer surface and mitigates edge effects during the CMP process.
