Title: John Shannon: Innovator in Field Emission Technology
Introduction
John Shannon is a notable inventor based in Surrey, GB. He has made significant contributions to the field of semiconductor technology, particularly in the development of field emission devices. With a total of 2 patents, his work has the potential to revolutionize display technologies.
Latest Patents
Shannon's latest patents include the "Field Emission Backplate" and the "Field Emission Device." The Field Emission Backplate is formed by laser crystallizing an area of amorphous semiconductor-based material. Emitter sites are created from the rough surface texture caused by the crystallization process. This process can be localized using laser interferometry, allowing for profiled emitter tips to grow on the localized crystalline areas. Such backplates can be utilized in field emission devices that emit into either a vacuum or a wide band gap light-emitting polymer. Additionally, a backplate with self-aligned gates can be formed by depositing an insulator layer and a metal layer over the emitter tips, followed by the removal of the top of the metal layer and etching away the insulator, leaving each tip surrounded by a metal rim. A planarizing agent can be employed to refine this process. The Field Emission Device patent addresses the need for improved properties in display devices, such as flat panel displays. It provides a field emission backplate made from a semiconductor-based material with a plurality of grown tips, along with at least one electro-luminescent or photo-luminescent material chemically attached to it.
