Title: Srihari Ponnekanti: Innovator in Substrate Processing Technologies

Introduction

Srihari Ponnekanti is a notable inventor based in Santa Clara, CA, who has made significant contributions to the field of substrate processing. With a total of 3 patents to his name, he has developed innovative technologies that enhance the efficiency and effectiveness of substrate processing systems.

Latest Patents

One of his latest patents is a substrate processing system configurable for deposition or cleaning. This apparatus is designed to process substrates by loading a cleaning process wafer onto the susceptor before forming a cleaning plasma in the processing chamber. In one embodiment, a ceramic wafer is selected for its dielectric value, which alters the electromagnetic field of the plasma and spreads it away from the susceptor during cleaning operations. This design minimizes damage to the susceptor and directs the plasma towards the chamber walls, thereby reducing cleaning time.

Another significant patent is a corrosion-resistant apparatus for processing substrates in corrosive process gas. This invention includes a process chamber, a process gas inlet for introducing gas into the chamber, a process gas exhaust for removing gas, and processing components for substrate processing. Notably, at least one component of the apparatus is made from an alloy comprising nickel and a eutectic component, which provides substantial resistance to corrosion from the process gas.
