Abstract
PURPOSE: To obtain a coordinate position signal of good linearity by forming a 2nd conduction type square or rectangular layer on the 1st surface of a 1st conduction type semiconductor wafer, by providing electrodes to two sides opposing to the 2nd conduction type layer, and by forming an electrode on the 2nd surface of the wafer.
CONSTITUTION: At square part 13 on the 1st surface of an n-type semiconductor wafer, p-layer 12 is formed and this part is used as a photo detection surface. Along two opposite sides of square 13, p+ regions 14 and 15 of high density are formed and on their surfaces, metal electrodes 17 and 18 are provided as output electrodes; and insulating layer 16 is formed at least at an exposed part of p-n junction of the 1st surface except electrodes and on the 2nd surface, n+ layer and electrode 20 are provided. The remaining part of the n-type semiconductor wafer is n-layer 11. When axis X and Y are considered to be in parallel to two sides 21 and 22 with no electrode, and electrodes respectively, spot light incident to the photo detection surface makes an incident position coordinate signal, under no influence of the y coordinate, appear at electrodes 17 and 18 in proportion to the X coordinate.
