摘要： Embodiments of the invention relate to methods for semiconductor chip package assembly. An embodiment of the invention includes providing a metallic leadframe with a chip mounting surface and a plurality of leadfingers. The leadfingers have a proximal end for receiving one or more wirebonds and a distal end for providing an electrical path from the proximal end. One or more of the leadfingers also has an offset portion and underlying heat spreader, increasing the stiffness of the leadfinger, and increasing leadfinger deflection-resistance and spring-back. The offset is in the direction opposite the plane of a heat spreader thermally coupled to the mounting surface. A semiconductor chip is affixed to the mounting surface and a plurality of bond pads of the chip are wirebonded to the offset portions of the proximal ends of individual leadfingers. The chip, the bondwires, portions of the heat spreader and leadfingers are encapsulated.

摘要： A packaged electronic device includes a thickness shaped IC die including a top portion, top surface, active circuitry, bottom portion and bottom surface. A cross sectional area of the bottom surface is ≧5% less than a cross sectional area of the top surface to provide a protruding lip having a bottom lip surface. A package substrate includes a top substrate surface including substrate bonding sites, a bottom substrate surface, and a die support structure on the top substrate surface having a gap region.

摘要： The invention provides semiconductor chip packages, tools, and methods for preventing and for correcting leadfinger deformation caused during wirebonding in semiconductor chip package manufacturing. Disclosed are improved heat blocks and methods for their use in ensuring adequate clearance between leadfingers and adjacent heat spreaders, as well as semiconductor chip package assemblies wherein a selected clearance between leadfingers and parallel surfaces may be assured. Methods of the invention include steps for supporting the proximal ends of the leadfingers using the wirebonding cavity of a heat block. Thus supported, a plurality of bondwires are attached to couple bond pads of the semiconductor chip to the proximal ends of leadfingers. Thereafter, the clearance between the wirebonded proximal ends of the leadfingers and the adjacent parallel surface of the heat spreader is adjusted using a spacing cavity of the heat block. In preferred embodiments of the invention, a plurality of bondwires couple a plurality of bond pads of the semiconductor chip to the proximal end of a single leadfinger, with assured clearance between the proximal end of the leadfinger and an underlying surface.

摘要： The invention relates to leadframes and semiconductor chip package assemblies using leadframes, and to methods for their assembly. A disclosed embodiment of the invention includes a semiconductor package leadframe with a chip mounting surface for receiving a semiconductor chip and a plurality of leadfingers. The leadfingers have a proximal end for receiving one or more wirebond, and a distal end for providing an electrical path from the proximal end. One or more of the leadfingers also has an offset portion at its proximal end for increasing the clearance between the leadfinger and underlying heat spreader, increasing the stiffness of the leadfinger, and increasing leadfinger deflection-resistance and spring-back. The offset is in the direction opposite the plane of a heat spreader thermally coupled to the mounting surface. Preferred embodiments of the invention further include a semiconductor chip affixed to the mounting surface and a plurality of bondwires operably coupling bond pads of the chip to the offset portions of the proximal ends of individual leadfingers.
