ABSTRACT:
An LED array is fabricated by forming an insulating film on a semiconductor substrate of a first conductive type, forming a plurality of windows in the insulating film, and diffusing an impurity of a second conductive type through these windows to create a plurality of diffusion regions. In addition, an anti-reflection coating consisting of one or more transparent dielectric thin films is formed on the diffusion regions where they are exposed in the windows. The thickness of the anti-reflection coating, or of its constituent thin films, is optimized for maximum transmission of light.
