Abstract:
A support member for supporting at least a portion of a semiconductor die assembly thereon comprising:a die pad having a surface having at least a portion thereof for directly attaching to at least a portion of a surface of a bare semiconductor die using a heat-activated die-attach material disposed between the at least a portion of the die pad and the at least a portion of the surface of the bare semiconductor die, the die pad comprising one of a portion of a lead frame, a printed circuit board, and a die attach portion of a die package, the lead frame including a lead frame having portions of a plurality of leads extending over the portion of the surface of the bare semiconductor die; a die cover for enclosing the bare semiconductor die, the die cover having at least a portion of a surface thereof for attachment to the die pad at an interface between the die pad and the die cover; a heat-activated electrically resistive attachment material; and an energizable resistance circuit interposed between the surface of the die cover and the die pad for attaching at least a portion of the die cover to the die pad, the resistance circuit for generating heat.
