    • The invention relates to a semiconductor device comprising a preferably discrete bipolar transistor with a collector region (1), a base region (2), and an emitter region (3) which are provided with connection conductors (6, 7, 8). A known means of preventing a saturation of the transistor is that the latter is provided with a Schottky clamping diode. The latter is formed in that case in that the connection conductor (7) of the base region (2) is also put into contact with the collector region (1). In a device according to the invention, the second connection conductor (7) is exclusively connected to the base region (2), and a partial region (2B) of that portion (2A) of the base region (2) which lies outside the emitter region (3) and comprises a smaller flux of dopant atoms. The bipolar transistor in a device according to the invention is provided with a pn clamping diode which is formed between the partial region (2B) and the collector region (1). Such a device has excellent properties, such as a short switching time (ts) and a saturation collector-emitter voltage (VCEsat) which is not too high, while having a low, non-variable and well reproducible leakage current, unlike the known device. In a favourable modification, a region (4) provided simultaneously with the emitter region (3) is present between the partial region (2B) and the second connection conductor (7).
    • 本发明涉及一种半导体器件,其包括具有集电极区域(1),基极区域(2)和设置有连接导体(6,7,8)的发射极区域(3))的优选分立的双极晶体管。 防止晶体管饱和的已知方法是后者具有肖特基钳位二极管。 在这种情况下,后者形成为基部区域(2)的连接导体(7)也与集电区(1)接触。 在根据本发明的装置中,第二连接导体(7)专门连接到基部区域(2),并且基部区域(2)的部分(2A)的局部区域(2B)位于 发射极区域(3)并且包括较小的掺杂剂原子通量。 根据本发明的器件中的双极晶体管设置有形成在部分区域(2B)和集电极区域(1)之间的pn钳位二极管。 这种器件具有优异的性能,例如开关时间短(ts)和饱和集电极 - 发射极电压(VCEsat),其不是太高,而具有低的,不可变的和良好重现的漏电流,与已知的器件不同 。 在有利的变型中,与发射极区(3)同时设置的区域(4)存在于部分区域(2B)和第二连接导体(7)之间。

In a device according to the invention, the second connection conductor (7) is exclusively connected to the base region (2), and a partial region (2B) of that portion (2A) of the base region (2) which lies outside the emitter region (3), as seen in projection, lying below the second connection conductor (7) is given a smaller flux of dopant atoms. The bipolar transistor in a device according to the invention is provided with a pn clamping diode which is formed between the partial region (2B) and the collector region (1). Such a device has excellent properties, such as a short switching time (ts) and a saturation collector-emitter voltage (VCEsat) which is not too high, while having a low, non-variable and well reproducible leakage current, unlike the known device. The reduced flux of dopant atoms of the partial region (2B) is preferably realized in that the partial region (2B) is given a smaller doping concentration and/or thickness than the remainder (2A) of the portion of the base region (2) which lies outside the emitter region (3). In a favourable modification, a region (4) provided simultaneously with the emitter region (3) is present between the partial region (2B) and the second connection conductor (7).
