Title: Innovations of Jonathan N Ishii

Introduction

Jonathan N Ishii is a notable inventor based in Fredericksburg, VA (US). He has made significant contributions to the field of electronic and photonic devices, holding two patents that showcase his innovative approach to technology.

Latest Patents

His latest patents include a method for fabricating electronic and photonic devices on a semiconductor substrate. This method involves initially patterning and etching multiple slabs on a substrate layer. An electronic device is fabricated on one slab while a photonic device is created on another, allowing both devices to coexist on the same substrate layer. Another patent focuses on an improved method for manufacturing vertical germanium detectors. This process begins with opening a detector window through an oxide layer on a single crystalline substrate. A single crystal germanium layer is then grown within this window, followed by the growth of an amorphous germanium layer on the oxide layer. The amorphous layer is polished until only a portion remains around the single crystal layer, after which a tetraethyl orthosilicate (TEOS) layer is deposited. An implant is performed on the single crystal layer, and a titanium layer is added to form the vertical germanium detector.
