Abstract
An ultraviolet sensitive photodiode is formed in a body of first conductivity type GaP. A region of second conductivity type with a graded impurity distribution is formed in the body, and a thin layer (preferably about 100A to 300A) is then removed from the front surface of the body. The removal of the thin layer significantly enhances the performance of the UV sensitive photodiode.
