Abstract: In a semiconductor device including a semiconductor element that produces heat and a substrate on which the semiconductor element is mounted, functions of the substrate are divided between a heat dissipating substrate and a wiring substrate. The heat dissipating substrate has a relatively high thermal conductivity, and includes principal surfaces defined by electric insulators, one of which is provided with an outer conductor located thereon. The wiring substrate is mounted on the upper principal surface of the heat dissipating substrate, has a thermal conductivity lower than that of the heat dissipating substrate, and includes a wiring conductor made mainly of silver or copper and located inside the wiring substrate, the wiring conductor being electrically connected to the outer conductor. The semiconductor element is mounted on the upper principal surface of the heat dissipating substrate and disposed in a through hole of the wiring substrate.

Abstract: A circuit board structure and a manufacturing method for a circuit board that ensures an electrical connection between a metal foil and a projection without using a conductive adhesive and is less likely to cause a decrease in the reliability of the connection due to the interlayer separation or the like is provided. A circuit board includes an insulating layer, a lower main surface wiring pattern and an upper main surface wiring pattern disposed on either side of the insulating layer, and an interlayer connection conductor passing through the insulating layer in a thickness direction and electrically connecting to the lower main surface wiring pattern and the upper main surface wiring pattern. The interlayer connection conductor is formed integrally with the lower main surface wiring pattern, and is bonded to the upper main surface wiring pattern via an intermetallic compound.

Abstract: In a metal base substrate with a low-temperature sintering ceramic layer located on a copper substrate, bonding reliability is increased between the copper substrate and the low-temperature sintering ceramic layer. A raw laminated body is prepared by stacking, on a surface of a copper substrate, a low-temperature sintering ceramic green layer including a low-temperature sintering ceramic material containing about 10 mol % to about 40 mol % of barium in terms of BaO and about 40 mol % to about 80 mol % of silicon in terms of SiO2, and this raw laminated body is subjected to firing at a temperature at which the low-temperature sintering ceramic green layer is sintered. In the thus obtained metal base substrate, a glass layer composed of Cu—Ba—Si based glass with a thickness of about 1 μm to about 5 μm is formed between the metal substrate and the low-temperature sintering ceramic layer.
