Abstract: A semiconductor device, including: a semiconductor element that has, formed at a first surface thereof: a pair of metal layers adjacent to each other, and an insulating layer interposed between the pair of metal layers; a metal wiring board that is bonded to the pair of metal layers of the semiconductor element respectively via a pair of bonding materials, the metal wiring board including a pair of regions thereof respectively overlapping with the pair of metal layers in a plan view of the semiconductor device; and a separation portion provided between the semiconductor element and the metal wiring board, and separating the pair of regions of the metal wiring board.

Abstract: There is provided a semiconductor module capable of determining a semiconductor chip in which a short-circuit failure has occurred without being disassembled. A semiconductor module includes IGBT provided in each of semiconductor chips connected in parallel, switching of which being controlled by a gate voltage based on a gate signal; two external terminals input with the gate signal; a first connection route group having a first connection route and a third connection route connecting the external terminal and the IGBTs provided in the semiconductor chips respectively; and a second connection route group having a second connection route and a fourth connection route connecting the external terminal and the IGBTs provided in the semiconductor chips respectively.

Abstract: A semiconductor device includes a wiring board, a semiconductor element disposed on the wiring board, and a lead having a bonding surface that is bonded to a main electrode of the semiconductor element by a bonding material. The main electrode includes a first pad and a second pad separated by an insulating layer extending in a first direction. The lead has at the bonding surface a recess that faces the main electrode so as to overlap the insulating layer and extends in the first direction. The recess has two outer ends in the first direction, one of which overlaps one end of the lead in plan view. The recess has a bottom surface that faces the main electrode of the semiconductor element, is not in contact with the bonding material and is continuous from the one of the two outer ends thereof to another end thereof in the first direction.

Abstract: For safely inserting a catheter into a chest cavity of a child or corpulent patient to be retained therein and for preventing atmospheric air from proceeding into the chest cavity during a removal of a penetrating needle, discharge equipment for medical procedures is provided which equipment includes a connector cap and a storage bottle detachably connectable to each other, a connector to be connected to the catheter retained in the patient, a check valve including an outer periphery covered by a protective cover and being openable only toward a storage bottle side, and a coupling device to the storage bottle mounted on the connector cap. The storage bottle is a hollow container including an inlet port and a discharge port, a detachably connecting device for the connector cap mounted on the inlet port, and a check valve openable only toward an exterior of the storage bottle is mounted on the discharge port.
