摘要： A semiconductor package comprising an LSI chip, a chip bump, an interposer, and a BGA bump is mounted at a predetermined position of a printed wiring board having a core layer. A heat sink for dissipating heat generated from the LSI chip is installed within the core layer. Further, heat radiating vias for conveying heat generated from the LSI chip to the heat sink are provided within the printed wiring board so that the BGA bump in the LSI chip is thermally liked with the heat sink. The heat generated from the LSI chip is mainly dissipated through a route of chip bump→interposer→BGA bump→heat radiating via→heat sink. By virtue of the above construction, the semiconductor device packaging structure can reduce the packaging volume of the heat sink while providing satisfactory cooling capacity and, at the same time, can minimize the length of signal wiring between LSI chips.

摘要： A semiconductor device includes two or more semiconductor modules which are stacked up into three-dimensional structure. Each semiconductor module includes a wiring board, one or more IC chips which are mounted on the wiring board, and one or more heat sinks which are attached to the IC chips via a thermal-conductive adhesive and are forcedly cooled by a coolant flowing through channels which are formed therein. The wiring board of each semiconductor module is provided with sockets having I/O pins and concavities. Electrical connection between adjacent semiconductor modules of the semiconductor device is established by inserting the I/O pins of the sockets of one semiconductor module into the concavities of the sockets of the other semiconductor module. The channels in the heat sink are implemented by a plurality of channel grooves which are generated between a plurality of fins which are formed in a cavity inside the heat sink at predetermined intervals. The coolant is supplied to the channel grooves from outside and the IC chips are forcedly cooled by the coolant. Therefore, enough cooling capacity is ensured by use of low-profile heat sinks, thereby both high processing speed (due to high packing density and short signal lines between IC chips) and sufficient cooling capacity are attained.

摘要： Behavior of a vapor bubble that emerges should be controlled to improve operational stability and reliability of a phase shift heat exchanger having a microchannel. The heat exchanger has a dual layer structure and includes a material that is elastically deformed according to pressure difference between the layers. The layers are connected, and at the connection interface a resistance unit that exerts a predetermined resistance against a coolant flowing from the coolant supplying layer toward the microchannel layer is provided, to maintain internal pressure of the coolant supplying layer higher than that of the microchannel, under a normal operation. Once a vapor bubble emerges, the relationship in strength of the internal pressure is turned over, and the elastic material is lifted so that the vapor bubble is dividedly distributed over a plurality of microchannels. Alternatively, the internal pressure of the coolant supplying layer may be maintained lower than that of the microchannel, so that once a vapor bubble emerges the vapor bubble is drawn to the lower pressure side.
