摘要:
In a method of manufacturing a semiconductor device, a first interlevel insulating film is formed on a silicon wafer. A metal film is formed on the first interlevel insulating film. The metal film is formed to form a first electrode wiring layer having an end located inside an end of the first interlevel insulating film on a peripheral portion of the silicon wafer. An insulating film is formed on the silicon wafer including the first interlevel insulating film and the first electrode wiring layer. A second interlevel insulating film having an end located outside the end of the first electrode wiring layer on the peripheral portion of the silicon wafer is formed by processing the insulating film. A device manufactured by this manufacturing method is also disclosed.

An optical transmission module includes a first transmission line for transmitting an electric signal, a resistance element used as a termination point, a second transmission line connected to the resistance element, and a surface ground pattern forming a coplanar line through the first and second transmission lines on a surface of a substrate. A modulator-integrated light-emitting element for outputting output light from an output end face is connected to the surface ground pattern. An electrode pad for modulator driving is located near the output end face on a top face of the modulator-integrated light-emitting element. The first transmission line and the electrode pad are connected by a first wire. The electrode pad and the second transmission line are connected by a second wire. A first notch portion is located in the substrate at a point of intersection between a propagation path of output light of the modulator integrated light-emitting element and a first side face of the substrate. The first and second transmission lines and the electrode pad are aligned.
