Title: The Innovations of Ronald E. Enstrom
Introduction
Ronald E. Enstrom is a notable inventor based in Skillman, NJ (US). He has made significant contributions to the field of semiconductor technology, holding a total of 5 patents. His work has advanced the understanding and application of photodiodes and semiconductor materials.
Latest Patents
One of his latest patents is for a "Rear entry photodiode with three contacts." This invention features a semiconductor photodiode that includes a substrate of semi-insulating indium phosphide, with a first layer of highly doped P-type indium phosphide on its surface. An active second layer of N-type indium gallium arsenide is positioned on the first layer, while a third layer of N-type indium gallium arsenide or indium phosphide is placed on the second layer. The third layer may be more highly doped than the second layer or may have a highly doped region on its surface. Additionally, a first contact is on the third layer, and a second contact is on the first layer. A buffer layer of lightly doped N or P-type indium phosphide may also be included between the first and second layers.
Another significant patent is for a "Silicon oxynitride passivated semiconductor body and method of making." This invention discloses a semiconductor body with an improved passivating layer. The device comprises a semiconductor material with regions of opposite conductivity types forming a junction that extends to the surface. The passivating layer consists of silicon oxynitride with a refractive index between about 1.55 and 1.75 and a substantial hydrogen content, which overlies the surface at the junction. The method for fabricating such a device involves vapor deposition of the passivating layer at low temperatures from an ambient with a specific ratio of silicon-containing to oxygen- and nitrogen-containing precursors.
