Abstract:
1. A method for packaging a microelectronic substrate, comprising: mounting the microelectronic substrate to a support member with a first surface of the microelectronic substrate facing the support member and a second surface of the microelectronic substrate facing opposite the first surface; electrically coupling the microelectronic substrate to the support member by passing wire bonds though an aperture in the support member and connecting one end of each wire bond to the support member and an opposite end of each wire bond to the microelectronic substrate; encapsulating the microelectronic substrate and at least a portion of the support member by disposing an encapsulating material over the support member and the second surface of the microelectronic substrate; directing a source of laser radiation toward the second surface of the microelectronic substrate to remove at least a portion of the encapsulating material adjacent to the second surface and expose the second surface; and forming a heat transfer feature in the encapsulating material by removing a portion of the encapsulating material to define an exposed external surface of the heat transfer feature.
