Introduction

Ravi Droopad is a notable inventor based in Tempe, Arizona, recognized for his contributions to semiconductor technology. With a total of seven patents to his name, he has made significant advancements in the field of materials science and engineering.

Latest Patents

One of his latest patents is focused on a semiconductor dielectric interface and gate stack. This invention discloses a semiconductor/dielectric interface that has reduced interface trap density, along with a method for manufacturing this interface. The method involves receiving a substrate containing a semiconductor, preparing the surface of the substrate, forming a termination layer bonded to the semiconductor, and depositing a dielectric layer above the termination layer without disrupting it. Notably, the termination layer can be configured to produce a single layer of oxygen atoms between the substrate and the dielectric layer.

Another significant patent involves a method of preparing crystalline alkaline earth metal oxides on a silicon substrate. In this process, a silicon substrate with amorphous silicon dioxide is heated to a temperature between 700°C and 800°C. It is then exposed to a beam of alkaline earth metal(s) in a molecular beam epitaxy chamber at a pressure within approximately 10^-9 to 10^-10 Torr. The surface is monitored using the RHEED technique to determine the conversion of amorphous silicon dioxide to crystalline alkaline earth metal oxide. This innovation allows for the formation of additional layers of material, which can be used in non-volatile and high-density memory device applications.
