Fabrication method for optical transmission channel board, optical transmission channel board, board with built-in optical transmission channel, fabrication method for board with built-in optical transmission channel, and data processing apparatus

摘要

A fabrication method for an optical transmission channel board includes a first step of forming on a substrate a layer containing an electrically conductive material, and a second step of patterning said layer containing an electrically conductive material formed on said substrate, and thereby forming circuit patterns at least a part of which is used as an electric circuit and at least a part of which positionally regulates an optical transmission channel.
