Title: AnKur Desai: Innovator in Semiconductor Processing

Introduction

AnKur Desai is a notable inventor based in Saint Peters, MO (US). He has made significant contributions to the field of semiconductor processing, holding 2 patents that showcase his innovative approaches.

Latest Patents

One of his latest patents is titled "Silicon wafering process flow." This method involves processing a semiconductor wafer sliced from a single-crystal ingot. The process includes plasma jet etching to reduce sub-surface wafer damage, followed by high-gloss etching to smooth the wafer's surface. Additionally, plasma-assisted chemical etching (PACE) is performed to enhance the flatness and thickness uniformity of the wafer, culminating in a final polish to further reduce surface roughness and nonspecularly reflected light.

Another significant patent is the "Process for reducing waviness in semiconductor wafers." This process utilizes plasma-assisted chemical etching to measure the surface profile at discrete points on one surface of the wafer. It computes a dwell time versus position map based on these measurements and selectively removes material from each surface to reduce waviness.
