Abstract
PURPOSE:To form plural units of photoconductive routes which cross each other with a prescribed angle onto a crystal substrate containing plural units of protrusions which are formed into a prescribed pattern with a surface selectively etched. In this way, a compact size and a high integration performance can be realized for the unit.
