    摘要: A composite ceramic sintered body is made from a ceramic matrix comprised mainly of silicon nitride, silicon oxynitride or an inorganic oxide selected from alumina, mullite, zirconia, high silica glass, lithium-aluminosilicate glass, magnesium-aluminosilicate glass or barium-magnesium-aluminosilicate glass, containing both whiskers and particles of a material selected from silicon carbide, silicon nitride, silicon oxynitride, alumina and zirconia dispersed therein. The whiskers have a diameter of 0.1 to 5 .mu.m and the particles have an average particle size of 5 to 60 .mu.m. The composite ceramic sintered body is homogeneous and isotropic, and it has a high strength and high toughness at a high temperature and an excellent heat resistance and oxidation resistance.

    摘要: Control electrode wirings which are led out from control electrodes over a number of chips built in a flat package and insulating members which are provided in order to insulate the control electrode wirings from main electrode wirings are also given function of positioning of the respective semiconductor chips in the flat package. Further, a one-piece control electrode wiring net is housed in the common electrodes of the package and the electrodes which are led out from the control electrodes of the respective semiconductor chips are connected to the net to simplify the processing of a large number of gate signal wirings.
