Abstract: PURPOSE:To reduce possibility of producing a wafer having a breakdown volt age of 190V or below while improving the yield by spacing a guard ring from a channel stopper by a distance of 40mum or more. CONSTITUTION:A pi layer 2 and an oxide film 3 are formed on a P<+>-type sub strate 1. A window corresponding to a light absorbing layer of an APD is opened in the structure.
