    • An integrated semiconductor circuit has a component formed of a semiconductor substrate with an active pn junction formed between a first semiconductor region of a first conductivity type and a second semiconductor region of a second conductivity type. The semiconductor circuit also has a protective circuit that is associated with the component and serves to dissipate overvoltages and/or electrostatic charges. The protective circuit has a protective pn junction formed in a semiconductor mount with a first semiconductor mount region of the first conductivity type and a second semiconductor mount region of the second conductivity type. The second semiconductor mount region of the second conductivity type is electrically coupled to the first semiconductor region formed in the semiconductor substrate of the first conductivity type.
    • 集成半导体电路具有由在第一导电类型的第一半导体区域和第二导电类型的第二半导体区域之间形成的具有活性pn结的半导体衬底形成的部件。 半导体电路还具有与部件相关联的保护电路,并用于消除过电压和/或静电电荷。 保护电路具有形成在具有第一导电类型的第一半导体安装区域和第二导电类型的第二半导体安装区域的半导体安装件中的保护性pn结。 第二导电类型的第二半导体安装区域电耦合到形成在第一导电类型的半导体衬底中的第一半导体区域。
