Abstract:
An ultraviolet light sensor and method of manufacturing thereof are disclosed. The ultraviolet light sensor includes Group-III Nitride layers adjacent to a silicon wafer with one of the layers at least partially exposed such that a surface thereof can receive UV light to be detected. The Group-III Nitride layers include a p-type layer and an n-type layer, with p/n junctions therebetween forming at least one diode. Conductive contacts are arranged to conduct electrical current through the sensor as a function of ultraviolet light received at the outer Group-III Nitride layer. The Group-III Nitride layers may be formed from, e.g., GaN, InGaN, AlGaN, or InAlN. The sensor may include a buffer layer between one of the Group-III Nitride layers and the silicon wafer. By utilizing silicon as the substrate on which the UV sensor diode is formed, a UV sensor can be produced that is small, efficient, cost-effective, and compatible with other semiconductor circuits and processes. The sensor may be configured to be sensitive to a specific subtype or subband of ultraviolet radiation to be detected by selecting a specific composition of said Group-III Nitride layers.

Claim (Index 13):
The method for manufacturing an ultraviolet light sensor according to  claim 1 , wherein said step of forming first and second conductive contacts comprises forming at least one of said contacts as a grid so as to allow ultraviolet radiation to travel past said at least one contact to a top layer of said Group-III Nitride layers.
