Patent ID: 8922229

Claim:
A method for measuring an electrical characteristic of a device under test (DUT), wherein the DUT includes a power device, the method comprising: mounting the DUT within a prober, wherein the prober includes a chuck, a test probe, and a signal unit, wherein the DUT includes a semiconductor device that is configured for high voltage and high power operation, and further wherein the test probe is configured to selectively provide electrical communication between the signal unit and a contact area of the DUT; blocking an electrical connection between the signal unit and the test probe when the test probe is not in electrical communication with the contact area; unblocking the electrical connection between the signal unit and the test probe when the test probe is in electrical communication with the contact area; and measuring the electrical characteristic of the DUT subsequent to the unblocking, wherein the measuring includes providing at least one of a high voltage test signal and a high power test signal from the signal unit to the DUT.
