Abstract
At least one method and system disclosed herein involves performing a time-dependent dielectric breakdown (TDDB) test and a bias temperature instability (BTI) test on a device. A device having at least one transistor and at least one dielectric layer is provided. A test signal is provided for performing a TDDB test and a BTI test on the device. The TDDB test and the BTI test are performed substantially simultaneously on the device based upon the test signal. The data relating to a breakdown of the dielectric layer and at least one characteristic of the transistor based upon the TDDB test and the BTI test is acquired, stored, and/or transmitted.
