    摘要： A cooling fin 9 is joined to a semiconductor element 1. A resin 10 encapsulates the semiconductor element 1. A portion of the cooling fin 9 projects from a lower surface of the resin 10. A cooler 11 has an opening 12. The cooling fin 9 projecting from the resin 10 is inserted in the opening 12 of the cooler 11. The lower surface of the resin 10 and the cooler 11 are joined to each other by a joining material 13 such as an adhesive. Therefore, a reduction in the number of component parts and a reduction in weight can be achieved, and compatibility between the heat conductivity and the strength of joining can be ensured.

    摘要： A semiconductor element is sandwiched between a lower and upper surface of a cooling body. A connection circuit and a communication device are provided on the lower surface of the cooling body. A drive circuit and a communication device are provided on the upper surface of the cooling body. These components are encapsulated by a resin. The connection circuit generates a control signal in response to a signal from outside. The communication device transmits the control signal. The communication device receives the control signal and supplies the control signal to the drive circuit, which drives the semiconductor element in response to the control signal. The resin electrically insulates the connection circuit and the communication device from the communication device and the drive circuit enabling prevention of breakdown of the connection circuit caused by an application of a high voltage from the drive circuit to the connection circuit.

    摘要： A circuit pattern is bonded to a top surface of a ceramic substrate. A cooling body is bonded to an undersurface of the ceramic substrate. An IGBT and a FWD are provided on the circuit pattern. A coating film covers a junction between the ceramic substrate and the circuit pattern, and a junction between the ceramic substrate and the cooling body. A mold resin seals the ceramic substrate, the circuit pattern, the IGBT, the FWD, the cooling body, and the coating film etc. The ceramic substrate has higher thermal conductivity than the coating film. The coating film has lower hardness than the mold resin and alleviates stress applied from the mold resin to the ceramic substrate. The circuit pattern and the cooling body includes a groove contacting the mold resin without being covered with the coating film.

    摘要： A sub-unit judges whether an instruction received from an external unit is executable. If the instruction is judged to be executable, the sub-unit executes it. If, on the other hand, the instruction is judged to be unexecutable, the sub-unit notifies the external unit of an executable plan.
