Title: Innovations by Steven D. Marcus: A Glimpse into His Patents and Career

Introduction

Steven D. Marcus, an accomplished inventor based in Tempe, Arizona, has made significant contributions to the field of materials science and silicon processing. With a portfolio of two patents, he continues to pave the way for innovative techniques in semiconductor technology.

Latest Patents

Steven D. Marcus's most recent patents focus on advancements in silicon oxynitride films and methods for rapid thermal processing (RTP) of ion-implanted silicon.

His first patent describes a silicon oxynitride film that is predominantly an oxide film at the interface with the substrate. Notably, the nitrogen content of the film increases as the distance from the silicon or silicon-germanium substrate grows. This innovative film is created through a method involving the rapid processing of a clean silicon wafer in a nitrogen-rich environment with a minimal presence of oxygen.

The second patent presents a method for RTP of a silicon substrate that has been implanted with dopant ions. This process entails contacting the surface with a reactive gas and employing a two-step processing technique to form a protective layer and activate dopants effectively. The result is a substrate with implanted areas achieving a sheet resistivity of less than 500 ohms per square, with careful control to prevent the movement of dopant ions beyond 80 nanometers from the surface.
