Photoreceptor array for optical encoder, has photoreceptors formed from semiconductor layer buried in trenches formed on insulating layer

摘要

An insulating layer (41) having trenches, is formed on a transparent substrate. Multiple photoreceptors formed from semiconductor layers, are buried in the trenches. An output signal line is formed on the photoreceptors via an interlayer insulator. Independent claims are also included for the following: (a) Optical encoder; (b) Method of manufacturing photoreceptor array
