Abstract
The semiconductor component has ESD protective elements configured outside the semiconductor body. The ESD protective elements connect an additional conductor track that carries a reference potential to conductor tracks of the leadframe. ESD protective structures integrated on the semiconductor body are no longer required. The correspondingly high area consumption is avoided.
Claims10
A semiconductor component comprising:
- a semiconductor body including an electronic circuit configured therein, said electronic circuit having a terminal for a signal to be processed, said electronic circuit having a stage connected to said terminal for the signal, said electronic circuit having a terminal for obtaining a supply potential, said terminal for obtaining the supply potential connected to said stage, said stage selected from a group consisting of an input stage and an output stage;
- a first conductor track running outside said semiconductor body, said first conductor track connected to said terminal for the signal;
- a second conductor track running outside said semiconductor body, said second conductor track connected to said terminal for obtaining the supply potential;
- an element for carrying an electrostatic discharge away from said terminal for the signal and to the supply potential;
- and
- a further conductor track running outside said semiconductor body, said further conductor track connected to said second conductor track;
- said element for carrying the electrostatic discharge disposed outside of said semiconductor body;
- and
- said element for carrying the electrostatic discharge connected outside of said semiconductor body to said further conductor track and to said first conductor track.
