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.

Abstract:
The radiation performance of a resin sealed semiconductor package is enhanced and further the fabrication yield thereof is enhanced. A drain terminal coupled to the back surface drain electrode of a semiconductor chip is exposed at the back surface of an encapsulation resin section. Part of the following portion and terminal is exposed at the top surface of the encapsulation resin section: the first portion of a source terminal coupled to the source pad electrode of the semiconductor chip and a gate terminal coupled to the gate pad electrode of the semiconductor chip. The remaining part of the second portion of the source terminal and the gate terminal is exposed at the back surface of the encapsulation resin section. When this semiconductor device is manufactured, bonding material and a film member are placed between the drain terminal and the semiconductor chip. At the same time, paste-like bonding material and a film member are placed between the source terminal 3 and gate terminal and the semiconductor chip. The paste-like bonding material is cured and turned into bonding material. As the result of use of the film members, variation in the thickness of the bonding material is suppressed.
