Magnet Mounting Apparatus for MTJ Device Testers

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.
