    摘要: A semiconductor device in which an element region including at least an IGBT region is formed on a semiconductor substrate is presented. The IGBT region including: a collector layer; a drift layer; a body layer; a gate electrode placed inside a trench extending from the front surface of the semiconductor substrate to the drift layer; an emitter layer; and a contact layer having a higher impurity concentration than the body layer. In the semiconductor device, assuming that an x direction is a direction in which the trench extends along the front surface of the semiconductor substrate and that a y direction is a direction orthogonal to the x direction along the front surface of the semiconductor substrate, a distance from the contact layer to the emitter layer in the x direction is larger than a distance from the contact layer to the trench in the y direction.

    摘要: When a semiconductor substrate of a semiconductor device is viewed from above, an isolation region, an IGBT region, and a diode region are all formed adjacent to each other. A deep region that is connected to a body region and an anode region is formed in the isolation region. A drift region is formed extending across the isolation region, the IGBT region, and the diode region, inside the semiconductor substrate. A collector region that extends across the isolation region, the IGBT region and the diode region, and a cathode region positioned in the diode region, are formed in a region exposed on a lower surface of the semiconductor substrate. A boundary between the collector region and the cathode region is in the diode region, in a cross-section that cuts across a boundary between the isolation region and the diode region, and divides the isolation region and the diode region. The collector region formed in the isolation region has a higher dopant impurity concentration than the collector region in the IGBT region.

    摘要: An overhead scanner includes a main body, a rotation unit supported by the main body and being rotatable around a rotation axis, an imaging unit mounted on the rotation unit and is configured to read a medium placed on a placement surface below the rotation unit, a light source that irradiates the medium with light, a driving unit that moves the rotation unit around the rotation axis toward a placement side, where the medium is placed, and a posture change detecting unit that detects posture change of the main body. When it is determined that the main body falls down based on the posture change detected, while the rotation unit is located at a readable position for reading the medium, the driving unit moves the rotation unit toward the standby position where the rotation unit is located when the imaging unit does not read the medium.
