Patent ID: 11693047

Abstract:
One example includes a cryogenic wafer test system. The system includes a first chamber that is cooled to a cryogenic temperature and a wafer chuck confined within the first chamber. The wafer chuck can be configured to accommodate a wafer device-under-test (DUT) comprising a plurality of superconducting die. The system also includes at least one wafer prober configured to implement a test on a superconducting die of the plurality of superconducting die via a plurality of electrical probe contacts. The system further includes a wafer chuck actuator system confined within a second chamber. The wafer chuck actuator system can be configured to provide at least one of translational and rotational motion of the wafer chuck to facilitate alignment and contact of a plurality of electrical contacts of the superconducting die to the respective plurality of electrical probe contacts of the at least one wafer prober.
