  • Patent number: 10962590
    Abstract: A magnet mounting apparatus including a cage, a magnet carriage and first actuator for use in testing Magnetic Tunnel Junction (MTJ) devices. The cage can be configured for mounting to an Automated Test Equipment (ATE). The magnet carriage can be configured for coupling to a wafer test magnet. The first actuator can be coupled between the cage and the magnet carriage. The first actuator can be configured to move the magnet carriage between a first position and a second position along a z-axis. The first position can be configured for locating the wafer test magnet within a predetermined proximity to a Device Under Test (DUT) wafer, and the second position can be configured for replacing a probe card.

  • Patent number: 10879457
    Abstract: Semiconductor substrate adaptor configured to adapt a substrate of a first dimension to a second dimension, such that the substrate can be properly supported by a supporting mechanism (e.g., a wafer cassette) customized for substrates of the second dimension. The substrate adaptor may be made of quartz. The combination of the substrate adaptor and a substrate fitting therein causes no perturbation in various aspects of a semiconductor process. Therefore, the substrate adaptor conveniently enables a substrate of the first dimension to be processed in the same processing equipment and conditions as a substrate of the second dimension. A vertical substrate adaptor may have a semicircular body with a semicircular cutout for accommodating a wafer and can support a wafer vertically. A horizontal substrate adaptor may have a circular body with a circular cutout for accommodating an entire wafer and supporting the wafer horizontally.
