摘要： A method for manufacturing a circuit board with high thermal dissipation includes the following steps: preparing a thermal conductive resin composition including 70 to 95 mass % of an inorganic filler and 5 to 30 mass % of a resin composition that includes a liquid thermosetting resin, a thermoplastic resin powder, and a latent curing agent; bonding the thermal conductive resin composition and a metal foil together by heating at a temperature lower than a temperature at which the thermosetting resin starts to cure while applying pressure so that the thermal conductive resin composition increases in viscosity and thus is solidified irreversibly; providing holes and curing the thermosetting resin to form an insulating substrate; and forming through holes and a circuit pattern. This method can achieve improved productivity and low cost in processing the holes. It is preferable that the thermal conductive resin composition is integral with a reinforcing material.

摘要： In a method of manufacturing a thermally conductive circuit board with high heat dissipation, high conductivity and high ground-connection, a sheet-like thermally conductive resin composition containing 70 to 95 wt. % inorganic filler and 5 to 30 wt. % thermosetting resin composition, a lead frame as a wiring pattern, and an electrically conductive heat sink with a metal pole placed therein are superposed, heated and compressed, and thus are combined to form one body. Consequently, a thermally conductive circuit board with a flat surface is obtained in which a grounding pattern is grounded to the heat sink inside the insulating layer. Thus, the grounding pattern and the heat sink can be connected electrically with each other in an arbitrary position inside the insulating layer of the thermally conductive circuit board. The method provides that a part of a lead frame and heat sink are connected not only mechanically, but also electrically, and allows an associated power module size to be reduced and its density to be increased.

摘要： A thermal conductive substrate includes a first electrical insulator layer, a second electrical insulator layer and a lead frame serving as a circuit pattern. The first electrical insulator layer is formed of a thermal conductive resin composition containing a thermosetting resin and an inorganic filler, and is joined to the lead frame. The second electrical insulator layer is provided on the side of the first electrical insulator layer not in contact with the lead frame, and is formed of a thermal conductive resin composition containing the inorganic filler and a resin composition containing the thermosetting resin. The second electrical insulator layer has a higher thermal conductivity than the first electrical insulator layer. Thus, it is possible to achieve higher heat-radiating characteristics and component packaging reliability without deteriorating formability and adhesive characteristics of the electrical insulator layers.

摘要： There is provided a flip-chip mounting resin composition which can be used for a flip-chip mounting process that is high in productivity and reliability and thus can be applicable to a flip-chip mounting of a next-generation LSI. This flip-chip mounting resin composition comprises a resin, metal particles and a convection additive 12 that boils upon heating the resin 13. Upon the heating of the resin 13, the metal particles melt and the boiling convection additive 12 convects within the resin 13. This flip-chip mounting resin composition is supplied between a circuit substrate 10 and a semiconductor chip 20, and subsequently the resin 13 is heated so that the molten metal particles self-assemble into the region between each electrode of the circuit substrate and each electrode of the semiconductor chip. As a result, an electrical connection is formed between each electrode of the circuit substrate and each electrode of the semiconductor chip. Finally, the resin 13 is allowed to cure so that the semiconductor chip 20 is secured to the circuit substrate 10, which leads to in a formation of a flip chip assembly.

摘要： A layered film of a three-layer clad foil formed with a first metal layer 23, a second metal layer 25, and an inorganic insulating layer 35 interposed therebetween is prepared. After the second metal layer 25 is partially etched to form a gate electrode 20g, the first metal layer 23 is partially etched to form source/drain electrodes 20s, 20d in a region corresponding to the gate electrode 20g. A semiconductor layer 40 is then formed in contact with the source/drain electrodes 20s, 20d and on the gate electrode 20g with the inorganic insulating layer 35 interposed therebetween. The inorganic insulating layer 35 on the gate electrode 20g functions as a gate insulating film 30, and the semiconductor layer 40 between the source/drain electrodes 20s, 20d on the inorganic insulating layer 35 functions as a channel.

摘要： A semiconductor module includes a circuit substrate composed of a wiring pattern, an electrical insulating layer and a thermal radiation board, and in use is fixed to an external thermal radiation member, in which the electrical insulating layer is composed of a thermal conductive mixture containing 70-95 wt % of an inorganic filler and 5-30 wt % of a thermosetting resin. A warping degree of the circuit substrate with respect to the external thermal radiation member is at most 1/500 of a length of the substrate, and the circuit substrate warps to protrude toward the thermal radiation board as the temperature rises. Accordingly, the thermal radiation property does not deteriorate even when the temperature rises in use. At a time of fixing the circuit substrate to the external thermal radiation member, the thermal resistance is kept to be a sufficiently low level. The thermal resistance is kept in a low level without sacrificing the contact between a module and the external thermal radiation member even at a high temperature during an operation of the device or the like, and the thermal conductive substrate is resistant to fractures or cracks and thus is highly reliable.
