Title: Innovations of Gerard J Sullivan
Introduction
Gerard J Sullivan is a notable inventor based in Thousand Oaks, CA (US). He has made significant contributions to the field of technology, particularly in the area of thin film transfer and optical modulation. With a total of 2 patents, his work has had a considerable impact on various applications in semiconductor technology.
Latest Patents
Sullivan's latest patents include a method of transferring a thin film to an alternate substrate. This method describes a process for transferring a thin film of arbitrarily large area from an original substrate to an alternate substrate. An etch stop layer is provided below an epitaxial layer, which is grown on a semiconductor substrate. In a single transfer process, the epitaxial layer is bonded to a rigid host substrate with desirable properties. The original growth substrate is then removed using the etch stop layer. In a double transfer process, the epitaxial layer is first bonded to a temporary substrate using a releasable resin. The original growth substrate is removed, allowing the epitaxial layer to be bonded to a rigid host substrate, and the temporary substrate is then removed to leave the transferred thin film attached to the host substrate.
Another significant patent is the transferred electron effective mass modulator. This optical modulator features a waveguide region comprising first and second layers of material with differing effective masses for free charge carriers. A mechanism is provided for moving charge carriers between the layers, which may include metal contacts and a power source for applying electrical fields. The optical modulator can also include a photodetector or a second control waveguide to alter electrical fields in response to optical signals.
