摘要: A method of manufacturing a waveguide optical semiconductor device provides substrate including lower clad layer, core an upper layer and contact formed on the in order. The part are removed by dry etching between pair parallel line patterns at independent rectangular pattern located near patterns. Then, remaining is wet so as to expose within pattern. An insulating material coated exposed layer. region that exposed. electrode Finally, bonding pad over
