Abstract
The present disclosure involves a method of packaging light-emitting diodes (LEDs). A carrier having a first side and a second opposite the first side is provided. The carrier includes a plurality of conductive interconnect elements. An integrated circuit (IC) die is bonded to the first side of the carrier. A packaging material having light-reflective properties is molded over the first and second sides of the carrier such that the IC die is sealed by the packaging material. A portion of the packaging material is molded into a reflective cap structure. A light-emitting diode (LED) is bonded to the second side of the carrier. Sidewalls of the reflective cap structure circumferentially surround the LED. The LED and the IC die are electrically coupled together through the conductive interconnect elements in the carrier. A lens is then formed over the LED.
