    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.
