Patent ID: 7312623

Claim:
A system for testing a plurality of micro-magnetic switches formed on a wafer, wherein each switch of the plurality of switches includes a cantilever and a coil, comprising: a wafer chuck that holds a wafer; at least one stepper motor that moves said wafer chuck to move the wafer; a magnet proximate to the wafer that is positioned adjacent to a first switch of the plurality of switches; a probe card proximate to the wafer that is positioned adjacent to the first switch, wherein the probe card mounts a first set of probes that interface with contact areas of a coil associated with the first switch, and a second set of probes that interface with conductors on the wafer associated with the cantilever of the first switch; a current source electrically coupled to the first set of probes, wherein the current source activates the coil of the first switch using the first set of probes to switch the cantilever from a first state to a second state; a source monitor unit electrically coupled to the second set of probes, wherein the source monitor unit determines whether the cantilever of the first switch is in the first state prior to the current source activating the coil of the first switch, and determines whether the cantilever is in the second state after the current source activates the coil of the first switch.
