MANUFACTURING METHOD OF AN OPTICAL CIRCUIT BOARD HAVING AN INTEGRATED STRUCTURE OF AN ELECTRIC WIRING REQUIRED FOR ELECTRIC SIGNAL TRANSMISSION AND AN OPTICAL WAVEGUIDE REQUIRED FOR OPTICAL SIGNAL TRANSMISSION

摘要

PURPOSE: A manufacturing method of an optical circuit board is provided to improve optical contact efficient in comparison with an optical waveguide having a contact part of a square shape by convexly forming the contact part of the optical waveguide contacted with a light source.;CONSTITUTION: A pattern groove for forming an optical waveguide is formed on a first surface of a top part of a copper foil(30). A first clad(31) is coated on a part or a whole part of the first surface of the copper foil. A core(33) of the optical waveguide is formed by filling a core material(32) inside the pattern groove formed in the copper foil. The core is formed by removing the core material remaining on a surface of the copper foil except for the pattern. A second clad(34) is formed on the core. An electrode pattern(35) is formed on a second surface of the copper foil by partially removing the second surface of the copper foil. Thickness of the electrode is reduce by half-etching the copper foil.;COPYRIGHT KIPO 2010
