摘要： A photo sensing device uses surface-emitting LED as light emitter to increase responsive of light receiver and prevent the short circuit of connection wires, and the manufacturing method thereof. The light emitter is directly mounted on top front surface of an encapsulating epoxy enclosing a light receiver. The light emitted from backside of the light emitter passes through the encapsulating epoxy and is directly absorbed by the light receiver. The response is enhanced as compared with prior art.
