Abstract:
1. A method for testing an integrated device under test (DUT) that is coupled to an automated testing equipment (ATE) using laser assisted device alteration (LADA), the method comprising: obtaining clock signal from the ATE and applying the clock signal to the DUT; obtaining a test loop signal corresponding to marginal setting of the DUT and applying the test loop signal to the DUT; applying a first feedback loop to a pulsed laser source to generate laser pulses at repeatable rate; applying the clock signal to a second feedback loop to synchronize the laser pulses to the clock signal; directing the laser pulses onto desired areas of the DUT; collecting electrical signals from the DUT; detecting whether the laser pulses alter the DUT response to the test loop signal applied to the DUT from the ATE.
