Abstract

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.
