Title: Aditya Walimbe: Innovator in Semiconductor Processing

Introduction

Aditya Walimbe is a notable inventor based in Tempe, AZ (US). He has made significant contributions to the field of semiconductor processing, holding 2 patents that showcase his innovative approaches to technology.

Latest Patents

Walimbe's latest patents include methods and apparatus for semiconductor processing preclean. This method involves removing an oxide layer from a substrate using anhydrous hydrogen fluoride in combination with water vapor. The system is designed to separate these components until they are delivered to a common volume near the substrate. To limit corrosion within the system's components, various strategies such as purification of anhydrous hydrogen fluoride and passivation of components are employed. Passivation is achieved by allowing anhydrous hydrogen fluoride to form a protective layer within the gas delivery component. Additionally, consistent water vapor delivery is facilitated by heating components with heaters.

Another significant patent involves apparatus and methods for selectively etching films. This invention focuses on maintaining the etch rate of a specific layer while preserving a non-etched layer. The etching process is accomplished by co-flowing a hydrogen precursor gas and a fluorine precursor gas into a remote plasma unit. The resulting gas mixture is then directed onto a substrate, allowing for the selective etching of a silicon oxide layer while keeping a silicon nitride layer intact.
