By connecting a protection diode (71) wherein p-anode layers (21) and n-cathode layers (22) are alternately formed in a polysilicon layer, and p-n junctions (74) that are in a reverse blocking state when there is a forward bias are alternately short circuited with a metal film (53), to a power semiconductor element (IGBT (72)), it is possible to achieve a balance between a high breakdown capability and a smaller chip area, a rise of breakdown voltage is suppressed even when a clamping voltage is repeatedly applied, and furthermore, it is possible to prevent destruction caused by a negative surge voltage input into a gate terminal (G).
摘要:
A coil failure detection circuit detects a rise of a collector current of an IGBT and a timer circuit measures the length of a rise period. If the rise is not a normal one, an electronic control unit judges that a coil failure has occurred. The electronic control unit turns off the IGBT to prevent misfires and stops a flow of fuel gas to a combustion chamber to prevent melting or deterioration of a catalyst.

A semiconductor device is disclosed that reduces the reverse leakage current caused by reverse bias voltage application and reduces the on-voltage of the IGBT. A two-way switching device using the semiconductor devices is provided, and a method of manufacturing the semiconductor device is disclosed. The reverse blocking IGBT reduces the reverse leakage current and the on-voltage by bringing portions of an n−-type drift region 1 that extend between p-type base regions and an emitter electrode into Schottky contact to form Schottky junctions.

A digital data reproducer, such as a VCR, reproduces digital data from a plurality of types of recording media. An equalizer includes a plurality of all-pass filters, for equalizing the reproduced digital data. A controller controls the equalization characteristics of the equalizer in accordance with the type of recording media, and controls the group delay characteristics of at least one of the plurality of all-pass filters. Thus, a single equalizer may be used for the plurality of types of recording media.

A reverse blocking semiconductor device that shows no adverse effect of an isolation region on reverse recovery peak current, that has a breakdown withstanding structure exhibiting satisfactory soft recovery, that suppresses aggravation of reverse leakage current, which essentially accompanies a conventional reverse blocking IGBT, and that retains satisfactorily low on-state voltage is disclosed. The device includes a MOS gate structure formed on a n− drift layer, the MOS gate structure including a p+ base layer formed in a front surface region of the drift layer, an n+ emitter region formed in a surface region of the base layer, a gate insulation film covering a surface area of the base layer between the emitter region and the drift layer, and a gate electrode formed on the gate insulation film. An emitter electrode is in contact with both the emitter region and the base layer of the MOS gate structure. A p+ isolation region surrounds the MOS gate structure through the drift layer and extends across whole thickness of the drift layer. A p+ collector layer is formed on a rear surface of the drift layer and connects to a rear side of the isolation region. A distance W is greater than a thickness d, in which the distance W is a distance from an outermost position of a portion of the emitter electrode, the portion being in contact with the base layer, to an innermost position of the isolation region, and the thickness d is a dimension in a depth direction of the drift layer.
