    摘要: A main circuit wiring pattern (4) formed on an insulating layer (3) of a main circuit substrate (1) is bonded with rear surfaces of semiconductor chips (5, 6) constituting a main circuit (10a) by a bonding material, such as solder. Front surface electrodes of the semiconductor chips (5, 6) are electrically connected to lead terminals (13a) used for power by bonding wires (11) having a relatively wide diameter. The rear surface of a control semiconductor chip (9) constituting a control circuit (10b) is bonded with a control circuit wiring pattern (8b) on a control circuit substrate (7) constituted by a bottom surface portion (12-1) of a case (12), which is bonded to a rim of the main circuit substrate (1), by a bonding material. A principal surface of the control circuit substrate (7) is located at a higher position than a principal surface of the main circuit substrate (1) so that a step is formed between these principal surfaces. Whereby, a semiconductor device, which excels in noise suppression and has a structure that can be manufactured with fewer manufacturing steps and at lower cost, can be provided.

    摘要: Sought is to provide a semiconductor module that makes it possible to easily perform visual observation of soldering, and to perform a reflow soldering process in a state where external terminals are attached to a case. A semiconductor module includes a rectangular base plate; a substrate which is placed on the base plate and on which a circuit including a semiconductor chip and so forth is formed; a rectangular parallelepiped case made of resin that is attached to the base plate and houses the substrate within; and a plurality of external terminals lower ends of which are fixed to the substrate with upper ends thereof being exposed on a top face of the case. The case is provided with a first case opening portion and a second case opening portion that are respectively formed by cutting off a front face and a rear face of the case from an upper edge thereof along a longitudinal direction thereof; and the top face of the case between the first case opening portion and the second case opening portion includes an external terminal holding portion to hold the plurality of external terminals along the longitudinal direction with the upper ends thereof being exposed. A sealing material is injected from the first case opening portion and the second case opening portion onto a top face of the substrate, and thereby the semiconductor module is sealed.
