    Abstract: A multiple-chip package has top and bottom pre-molded leadframes formed prior to the flip-chip attachment of semiconductor die to the leadframes. After die attachment, underfill is used to encase all but one surface of the die, and the top and bottom leadframes are joined together by solder bump balls with the exposed surfaces of the semiconductor dice proximate to each other.

    Abstract: A stacked semiconductor package technique applicable to semiconductor chips having pins short enough that the semiconductor chips cannot be directly bonded together is provided. A printed circuit board (PCB) is inserted into a space between pins of an upper semiconductor chip and the exterior of bodies of stacked semiconductor chips. The PCB includes a plurality of conductive patterns at locations corresponding to the respective pins. The respective conductive patterns and the corresponding respective pins of the upper and lower semiconductor chips are bonded together. The PCB includes a plurality of recess patterns on one side, the recess patterns having the same pitch as the pins of the semiconductor chips. The PCB is disposed across the pins of the lower semiconductor chip, and thereby easily arranged with the stacked semiconductor chips.
