Abstract:
A stack package includes a lower package including a lower package substrate and a lower semiconductor chip disposed on the lower package substrate, an upper package including an upper package substrate and an upper semiconductor chip disposed on the upper package substrate, a fastening element formed between a top surface of the lower semiconductor chip and a bottom surface of the upper package substrate, and a halogen-free inter-package connector connecting the lower package substrate to the upper package substrate.
Abstract:
FIG. 1 is a front perspective view of a television receiver showing our new design; FIG. 2 is a front view thereof; FIG. 3 is a rear view thereof; FIG. 4 is a left-side view thereof; FIG. 5 is a right-side view thereof; FIG. 6 is a top view thereof; FIG. 7 is a bottom view thereof; and, FIG. 8 is a rear perspective view thereof. The evenly-dashed broken lines in the figures depict portions of the television receiver and form no part of the claimed design.
Abstract:
Provided are a stacked package, a method of fabricating a stacked package, and a method of mounting the stacked package fabricated by the same. The method of fabricating a stacked package includes providing an upper semiconductor package including an upper package substrate, upper semiconductor chips formed on a top surface of the upper package substrate, and first solders formed on a bottom surface of the upper package substrate and having a first melting temperature, providing a lower semiconductor package including a lower package substrate, lower semiconductor chips formed on a top surface of the lower package substrate, and solder paste nodes formed on the top surface of the lower package substrate and having a second melting temperature lower than the first melting temperature, and forming inter-package bonding units by attaching respective first solders and solder paste nodes to each other by performing annealing at a temperature higher than the second melting temperature and lower than the first melting temperature.
