A chip stack package may include a package substrate, a plurality of semiconductor chips mounted on the package substrate, bonding wires electrically connecting the semiconductor chips to the package substrate, and spacers interposed between the adjacent semiconductor chips. Each of the spacers may include a plurality of metal bumps. The spacers may be higher than the highest point of the bonding wire from the active surface of the semiconductor chip.

In one embodiment, a semiconductor package includes a first insulating body and a first semiconductor chip having a first active surface and a first back surface opposite the first active surface. The first semiconductor chip is disposed within the first insulating body. The first active surface is exposed by the first insulating body. The first back surface is substantially surrounded by the first insulating body. The semiconductor package includes a post within the first insulating body and adjacent to a side of the first semiconductor chip.

摘要:
A method for manufacturing semiconductor devices is provided in which an organic adhesive layer is formed on the backside of a semiconductor wafer after being thinned by a backlapping process and cured to form a B-stage adhesive layer. Using the B-stage adhesive layer, the semiconductor device may then be attached to a circuit substrate and then subjected to additional curing to form a C-stage adhesive layer. Such semiconductor devices may also be attached directly to a lower semiconductor chip or, in the alternative, may be attached to a spacer mounted that is or will be mounted on a lower semiconductor chip or the circuit substrate. The organic adhesive is selected to counteract stresses induced by a passivation layer formed on the active surface, thereby reducing or preventing warping of the semiconductor wafer and eliminating the need for a separate resin paste adhesive during the chip attaching process.

A semiconductor package and module, and methods of fabricating the same are provided. A method of fabricating a semiconductor package may include bonding rear surfaces of first and second semiconductor chips to each other, each of the semiconductor chips having chip pads exposed on front surfaces. The method may also include forming an encapsulation portion configured to encapsulate side surfaces of the bonded semiconductor chips, forming via plugs configured to pass through the encapsulation portion, forming an insulating layer configured to expose surfaces of the chip pads and the via plugs on the exposed surfaces of the two semiconductor chips and surfaces of the encapsulation portion, and forming package pads on the exposed surfaces of the chip pads and the surfaces of the via plugs.
摘要:
A method of manufacturing a semiconductor device includes forming printed circuit board (PCB) having an embedded interposer. A semiconductor chip or a semiconductor package is mounted onto the embedded interposer using a conductive adhesive agent. The embedded interposer has substantially the same coefficient of thermal expansion (CTE) as the semiconductor chip. The embedded interposer is formed using a semiconductor wafer.

摘要:
A package substrate may have an improved surface structure for controlling the flow of an adhesive. The package substrate may have an upper surface and a lower surface covered with a passivation layer. A window may be provided in, for example, the center of the package substrate. Sinks may be provided on the lower surface, clear of the passivation layer. The semiconductor package may have an indented or non-planar surface structure.

A semiconductor package may include a printed circuit board having a conductive bump pad. At least one semiconductor chip may be electrically connected to the printed circuit board. A lead free conductive bump may be mounted on the conductive bump pad. The lead free conductive bump may include no more than about 0.3% by weight of copper. The lead free conductive bump may include about 3.0% to about 4.0% by weight of silver, about 0.1% to about 0.3% by weight of copper and about 95.7% to about 96.9% by weight of tin.
