  • Process and circuit for protection of test contacts in high current measurement of semiconductor components
    Patent number: 7295021
    Abstract: To limit the current in heavy current testing of semiconductor components with test needles, upstream of each needle a circuit is connected which has low resistance in the range of allowable currents and has high resistance above a given limit current in order to limit the current. The current source which undertakes limitation in the electrical supply lead to the probes is galvanically separated from the voltage supply of the current source itself.
