摘要： A pulsed current generator circuit for providing current pulses to a device under test includes a current source for applying a current to the device under test and a controlled current shunt for shunting current from the device under test. A booster circuit is provided for supplying a booster current to the device under test when the controlled current shunt is opened and current again flows through the device under test, thereby facilitating recharge of a parasitic capacitance associated with the device under test

摘要： In accordance with an aspect, a thermally-controllable integrated unit is configured to hold devices under test. The integrated unit includes at least one heater board, comprised of a thermally-conductive material and provided with at least one global heater configured to globally heat the DUT board. A DUT board of the integrated unit includes a DUT board in thermal contact with the at least one heater board, the DUT board including a plurality of sockets, each socket configured to hold at least one DUT. The DUT has conductor paths to conduct electrical signals between test equipment and the terminals of DUTs in the sockets. Each socket includes an associated temperature sensor and a separately controllable local heater configured to, based on a temperature indication from the temperature sensor, heat a DUT in that socket.

摘要： A pulsed current generator circuit for providing pulses to a device under test includes a current source for applying a current to the device under test and a controlled current shunt for shunting current from the device under test. A booster circuit (10) is provided for supplying a booster current to the device under test when the controlled current shunt (Qs) is opened and current again flows through the device under test, thereby facilitating recharge of a parasitic capacitance associated with the device under test.

摘要： Pulsed current circuitry for electromigration testing of semiconductor integrated circuits and components. The circuit includes a multiplexer that outputs analog voltage pulses, and is capable of generating both bipolar and unipolar voltage pulses. At least one operational amplifier and resistor receive the voltage pulses from the multiplexer and convert the voltage pulses to current pulses. A charge booster circuit is provided for minimizing overshoots and undershoots during transitions between current levels in the test circuit.
