    摘要: Field plates for relaxing electric fields are provided for an active element in a semiconductor integrated circuit. A field plate integral with an electrode making ohmic contact with an elongated strip shaped diffusion region and extending beyond a pn-junction formed between the diffusion region and an adjacent region to surround the pn-junction has a larger width at its opposite ends than a width at its linear portions. A high breakdown voltage can be obtained by thus configuring the field plate without changing the diffusion region in size.

    摘要: A semiconductor switch assuring the easy formation of a semiconductor integrated circuit and having high control sensitivity while maintaining high dv/dt - immunity, which comprises a PNPN switch of an equivalently four-layered structure including at least three PN-junctions, an anode and a cathode, switching means including a control terminal and connected with the PNPN switch to shunt one of the three PN-junctions at either one end of the PNPN switch, amplifying means, and a capacitive element for differentiating a voltage applied between the anode and the cathode of the PNPN switch to allow a current to flow into the control terminal of the switching means through the amplifying means, so that the switching means is driven by the current thereby to short-circuit the one of three PN-junctions.

    摘要: A thyristor highly proof against dv/dt in which to prevent malignition due to the displacement current produced by the application of an abruptly rising forward voltage or the internal leakage current increasing with the temperature rise of the semiconductor substrate, an auxiliary electrode is provided to the intermediate region adjacent to one of the outermost regions of the semiconductor substrate to which two main electrodes, anode and cathode, are provided, the auxiliary electrode and the main electrode on the one outermost region being connected electrically, and a control region having the opposite conductivity type to that of the intermediate region is formed in the intermediate region between the auxiliary electrode and the main electrode on the one outermost region, the control region being provided with a gate electrode. By supplying a control signal to the gate electrode a depletion layer is produced in the intermediate region such that the path of the control signal from the gate electrode to the auxiliary electrode is completely blocked and the control signal is all utilized for the ignition. The displacement current and the leakage current are bypassed from the auxiliary electrode to the main electrode on the one outermost region.
