Claim:
1. A method, comprising: placing a semiconductor die on a first adhesion layer, the semiconductor die including a sensor area on a first side of the semiconductor die, the first side of the semiconductor die facing away from the first adhesion layer; placing a first lens over the sensor area of the semiconductor die; placing a light emitting assembly over the first adhesion layer, the light emitting assembly including a light emitting device having a light emitting area and a second lens positioned over the light emitting area, the light emitting area facing away from the first adhesion layer; forming an encapsulating layer at least partially on the semiconductor die, the first lens, and the light emitting assembly to form a proximity sensor assembly having a first side, the first side facing away from the first adhesion layer; separating the proximity sensor assembly from the first adhesion layer; placing the proximity sensor assembly on a second adhesion layer, the first side of proximity sensor assembly facing the second adhesion layer; and forming a redistribution layer on a second side of the proximity sensor assembly.
