Abstract:
A method of manufacturing a photosensitive semiconductor device, comprising:preparing a first lead frame having a first island with a concave portion defined in an end thereof;preparing a second lead frame having a second island;fixing a smaller one of a photo-emitting semiconductor device and a photo-detecting semiconductor device to said first island;fixing another one of said photo-emitting semiconductor device and said photo-detecting semiconductor device to said second island;filling a translucent resin in a state in which said photo-emitting semiconductor device and said photo-detecting semiconductor device are opposed to each other, to thereby connect said photo-emitting semiconductor device and said photo-detecting semiconductor device to each other, said filling a translucent resin including filling through the concave portion; andforming a sealing material for surrounding said translucent resin.
