Claim 7:
8. A biosensor system, comprising:
a handling substrate;
an interconnect layer over the handling substrate;
a device substrate over the interconnect layer, the device substrate including a biosensor array electrically connected to the interconnect layer;
an isolation layer over the device substrate; and
a plurality of electrodes formed over the isolation layer and extending through the isolation layer and the device substrate to the interconnect layer, the plurality of electrodes being positioned on four sides of the biosensor array;
wherein the plurality of electrodes include:
first, second, third and fourth electrodes positioned on a common plane on respective first, second, third and fourth sides of the biosensor array;
fifth, sixth, seventh and eighth electrodes positioned on the common plane on the respective first, second, third and fourth sides of the biosensor array;
a reference electrode positioned above the plurality of electrodes and the biosensor array; and
a controller configured to selectively energize the plurality of electrodes to generate a DEP force to selectively position a test sample relative to the biosensor array.
