Abstract:
A wafer stacked semiconductor package (WSP) having a vertical heat emission path and a method of fabricating the same are provided. The WSP comprises a substrate on which semiconductor chips are mounted; a plurality of semiconductor chips stacked vertically on the substrate; a cooling through-hole formed vertically in the plurality of semiconductor chips, and sealed; micro holes formed on the circumference of the cooling through-hole; and a coolant filling the inside of the cooling through-hole. Accordingly, the WSP reduces a temperature difference between the semiconductor chips and quickly dissipates the heat generated by the stacked semiconductor chips.

Provided are a heat sink and a heat sink semiconductor module assembly which may include an improved, cooling function. Each of the heat sinks may include a flat heat sink base having a first surface attached to semiconductor devices and a second surface externally exposed; first fins provided on a portion of the second surface of the heat sink base to which no clip is coupled; and second fins provided on portions of the second surface of the heat sink base to which a clip may be coupled. The semiconductor module assembly may secure the heat sinks to both surfaces of a semiconductor module using the clip. Accordingly, air may flow smoothly through the second fins on the portions to which the clip may be coupled, thereby improving the cooling function of the heat sinks.

Abstract:
A method for matching an upper protocol layer to a high speed serial bus is provided. The method includes the steps of (a) determining whether the length of the data packet transferred from an upper layer to a node of the high speed serial bus is no less than a predetermined length, (b) allocating a channel of the bus and transferring data by an isochronous transfer service when it is determined that the length of the data packet is no less than the predetermined length, and (c) transferring data by an asynchronous transfer service when it is determined that the length of the data packet is less than the predetermined length. According to the above method, it is possible to match an existing communications application where it is not specified which service of the high speed serial bus is to be used to the high speed serial bus, while maintaining transparency of communication protocol and to effectively use the channel resources of the bus.
Abstract:
A stack semiconductor package includes a first semiconductor package having a first package substrate and a first semiconductor chip mounted on the first package substrate. The first semiconductor chip includes first chip pads arranged along a side portion thereof. The stack semiconductor package includes a second semiconductor package disposed on the first semiconductor package, and includes a second package substrate.

Each of the first and second sub-chips includes second chip pads arranged along a side portion thereof. Connection wiring paths between interface portions and connection pads may be reduced and simplified, thereby preventing connection wires from being tangled. Moreover, connection wiring paths between a logic chip and a memory chip may be minimized, thereby providing high speed performance.
