    摘要： In one embodiment, an LED bulb includes a plurality of metal lead frame strips, including at least a first strip, a second strip, and a third strip. First LED dies have their bottom electrodes electrically and thermally connected to a top surface of the first strip. Second LED dies have their bottom electrodes electrically and thermally connected to a top surface of the second strip. The top electrodes of the first LED dies are wire bonded to the second strip, and the top electrodes of the second LED dies are wire bonded to the third strip to connect the first LED dies and second LED dies in series and parallel. The strips are then bent to cause the LED dies to face different directions to obtain a wide emission pattern in a small space. The strips are then enclosed in a thermally conductive bulb having electrical leads.

    摘要： The present invention relates to a thermally enhanced semiconductor assembly and a method of making the same. In accordance with one preferred embodiment, the method includes: forming a stopper on a metal layer; mounting a semiconductor device on the metal layer using the stopper as a placement guide for the semiconductor device; attaching a stiffener to the metal layer; forming a build-up circuitry that covers the stopper, the semiconductor device and the stiffener; providing a plated through-hole that provides an electrical connection between the build-up circuitry and the metal layer; and removing selected portions of the metal layer to form a thermal pad and a terminal. Accordingly, the thermal pad can provide excellent heat spreading, and the stopper can accurately confine the placement location of the semiconductor device and avoid the electrical connection failure between the semiconductor device and the build-up circuitry.
