Title: The Innovations of Stephen M Spaziani

Introduction

Stephen M Spaziani is a notable inventor based in Nashua, NH (US). He has made significant contributions to the field of optical detection technology, holding a total of 5 patents. His work primarily focuses on improving the performance of photodiodes, which are essential components in various electronic devices.

Latest Patents

One of his latest patents is the "Vertical structure Schottky diode optical detector." This invention features a vertical structure Schottky contact photodiode that includes a narrow bandgap InGaAs light absorbing layer. This layer is cladded with InAlAs current blocking layers, which have metal contacts formed on them. Compared to single-side MSM photodiodes, this design improves response time due to reduced spacing between the electrodes. Additionally, the capacitance is lowered because of the inherently low doping levels in the semiconductor material. The laterally offset finger electrodes are made light reflective to enhance carrier production in the InGaAs absorption layer.

Another significant patent is for "Transparent ohmic contacts for Schottky diode optical detectors on thin." In this invention, an InP buffer layer is formed on an InP substrate, followed by a thin layer of heavily doped InGaAs, a thick layer of light absorbing InGaAs, and a thin layer of InAlAs. A light reflective Schottky barrier metallic layer is then applied to the InAlAs layer. The device is inverted and affixed to a new substrate to protect the sensitive Schottky contact. After removing the InP substrate layers, the exposed thin, heavily doped InGaAs layer is coated with a transparent, electrically conductive layer of Indium-tin-oxide.
