Title: Innovations by John Fuhriman

Introduction

John Fuhriman is a notable inventor based in San Luis Obispo, CA (US). 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 3 patents to his name, Fuhriman's work has had a considerable impact on the semiconductor industry.

Latest Patents

One of Fuhriman's 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, enabling independent regulation of pressure to control the downward force acting on the wafer during the CMP process. Additionally, an edge control bladder can be included within the carrier, allowing for adjustments to the force on the wafer's edge. By managing the pressures of the retaining ring actuator, inflatable membrane, and edge control bladder, Fuhriman's invention addresses non-uniformities in the wafer surface and mitigates edge effects during CMP.
