Latest Patents
Christopher Theis holds a patent for a non-hermetic APD designed for operation in moisture-containing ambiances. This invention comprises an InP/InGaAsP-containing Group III-V compound semiconductor body with a p-n junction formed within it. The junction typically intersects the top surface of the body. A patterned dielectric layer is strategically formed on the surface to cover regions intersected by the junction. An electrode is created in an opening in the dielectric layer to establish electrical contact with one side of the junction. Notably, the thickness of the dielectric layer is engineered to reduce leakage current to less than about 1 nA when the operating voltage ranges from 20 to 100 V. In a preferred embodiment, the dielectric layer's thickness exceeds 2 µm when the applied voltage is above 20 V. The composition of the dielectric layer may consist of inorganic materials, such as silicon nitride, or a combination of inorganic and organic materials. This innovative approach enhances the performance and reliability of APDs in challenging environments.
