Abstract:
1. A method for manufacturing a semiconductor device comprising: preparing a first frame and a second frame, setting the first frame and the second frame in a die that has a first cavity, a second cavity, a gap in communication with the first cavity and the second cavity, a through gate in communication with the first cavity and the second cavity, and a runner in communication with the second cavity, wherein the first light emitting element and the first light receiving element are placed in the first cavity, the second light emitting element and the second light receiving element are placed in the second cavity, and the connecting portion is placed in the gap; forming a first resin body by filling the first cavity, the second cavity, and the gap with a first resin through the runner and the through gate; removing parts of the first resin body formed in the runner and the through gate; and forming the second resin body that covers the first resin body.
