Title: The Innovations of William J. White: A Pioneer in Photodiode Technology

Introduction: William J. White, based in Chelmsford, MA, is a prolific inventor with an impressive portfolio of 16 patents. His innovations primarily focus on photodiode technology, contributing significantly to advancements in this field.

Latest Patents: Among his most notable patents is the "Glue-free backside illuminated photodiode apparatus and fabrication process." This invention describes an apparatus and a method for fabricating a backside illuminated photodiode array without utilizing epoxy. The advantage of this approach is improved transmission characteristics, utilizing indium or other cold-weldable metals to fasten the detectors to the transmissive substrate. Additionally, the indium serves as an optical mask for each detector element due to its opacity in the waveband of detector sensitivity. Another significant patent is the "Tilted array with parallel cold shield." This cold shield, designed for an array of detectors, comprises a first cover of radiation-blocking material with parallel rows of apertures positioned at a specific distance from the detectors. It also includes a second cover of a similar material with multiple apertures lying closer to the detectors. This design minimizes background radiation while allowing desirable radiation from various angles to reach the detectors.
