Patent ID: 8492181

Claim:
A method of forming an embedded wafer level optical package comprising: attaching a sensor die, PCB bars and an LED on adhesive tape laminated on a carrier; attaching a dam between two light sensitive sensors of the sensor die; encapsulating the sensor die, the PCB bars, the LED, and the dam in an encapsulation layer; debonding the carrier; grinding a top surface of the encapsulation layer; forming vias through the encapsulation layer to the sensor die and the LED; filling the vias with conductive material; metalizing the top surface of the encapsulation layer; dielectric coating of the top surface of the encapsulation layer; dielectric coating of a bottom surface of the encapsulation layer; patterning the dielectric coating of the bottom surface of the encapsulation layer; and plating the patterned dielectric coating of the bottom surface of the encapsulation layer.
