    • A field effect semiconductor component has a bipolar transistor structure in a semiconductor body consisting of a lightly doped upper area of a first conductivity type as base region and of a lower heavily doped area as emitter region with a complementary conductivity type. Between the base region and the emitter region, a horizontal pn junction forms. The emitter region is in resistive contact with a large-area emitter electrode on the rear of the semiconductor component. On the top of the semiconductor component, a first insulated gate electrode and a second insulated gate electrode are arranged adjacently in the area close to the surface. A vertical pn junction region insulated from the upper area is arranged in such a manner that a collector region and the base region of the bipolar transistor structure can be controlled via the insulated gate electrodes (G1 and G2) arranged electrically separately.
    • 场效应半导体元件在半导体主体中具有双极晶体管结构,该半导体主体由作为基极区的第一导电类型的轻掺杂上部区域和作为具有互补导电类型的发射极区域的较低重掺杂区域组成。 在基极区域和发射极区域之间形成水平pn结。 发射极区域与半导体元件后面的大面积发射极电阻接触。 在半导体部件的顶部,第一绝缘栅电极和第二绝缘栅电极相邻布置在靠近表面的区域中。 与上部区域绝缘的垂直pn结区域被布置成使得双极晶体管结构的集电极区域和基极区域可以经由绝缘栅极电极(G< 1>和& 电气分开排列。
