Abstract:
1. A test apparatus for testing a semiconductor die, the test apparatus comprising: a test jig configured to accommodate the semiconductor die; a power source connected to the test jig and configured to supply current to the semiconductor die; a current sensor coupled to the test jig, the current sensor configured to sense current passing through the semiconductor die; an electronically operable current breaker connected to the test jig, the electronically operable current breaker configured to selectively complete and break a circuit that includes the power source; a computer configured to receive signals from the current sensor and to selectively cause the electronically operable circuit breaker to break the circuit including the power source in response to receiving signals from the current sensor indicating that a fault has occurred in the semiconductor die, the computer further configured to selectively cause the electronically operable circuit breaker to complete the circuit that includes the power source in response to the fault being removed; and an interface connectable between the computer, the current sensor and the electronically operable current breaker, wherein the interface allows the computer to connect to the current sensor and the electronically operable current breaker through a port on the computer.
