    摘要: A semiconductor switching device of field-drive type includes a bipolar component having a pnp transistor portion (8) and a npn transistor portion (9), said pnp transistor portion (8) and said npn transistor portion (9) being connected to cause a positive feedback, and a n-channel MOS transistor (11) connected across an emitter electrode (n3) and a collector electrode (n2) of said npn transistor portion (9), wherein a p-channel MOS transistor (10) is connected across an emitter electrode (p1) and a connector electrode (p2) of the pnp transistor portion (8), and a control terminal of said n-channel MOS transistor (11) is electrically connected with a control terminal of said p-channel MOS transistor (10). Said device is operable to control the main drive section even in the floating state and to drive the main drive section by a small control current.

    摘要: A resistance element capable of withstanding a high voltage is formed through impurity diffusion in a single crystal island (1) of a semiconductor integrated circuit substrate. The resistance element includes a resistive region (2; 16) formed in an exposed surface of the single crystal island (1) and folded reciprocatively by at least one and a half turns in a planar zigzag-like pattern. The pitch at which the resistive region is folded is decreased as viewed in the direction in which extension of depletion layer formed within the single crystal island upon application of a voltage between two ends of the resistive region is decreased.

    摘要: A lateral transistor having a high breakdown voltage and operable with an improved current amplification factor and an improved cut-off frequency comprises in a semiconductor substrate (14) of one conductivity type, a base layer (16) of the one conductivity type and an emitter layer (11) of the other conductivity type formed in the base layer. A first collector layer (12) of the other conductivity type is formed in the one principal surface of the substrate apart from the base layer and a second collector layer (13) of the same conductivity type having an impurity concentration lower than that of the first collector layer is formed between the first collector layer and the base layer in contact with the latter layers. Emitter, base and collector electrodes (17,18,19) make ohmic contact with the emitter, base and first collector layers respectively. The emitter electrode extends on a passivation film (15) covering the one principal surface of the substrate to terminate at a point on the second collector layer.
