Claim 12:
13. A method, comprising:
providing a handling substrate;
providing an interconnect layer over the handling substrate,
providing a device substrate over the interconnect layer, the device substrate including a biosensor array electrically connected to the interconnect layer;
providing an isolation layer over the device substrate;
providing 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 configured to receive an AC signal to establish a DEP force to selectively position a three-dimensional (3D) test sample relative to the biosensor array, wherein the plurality of electrodes include:
first, second, third and fourth electrodes positioned on respective first, second, third and fourth sides of the biosensor array; and
fifth, sixth, seventh and eighth electrodes positioned on the respective first, second, third and fourth sides of the biosensor array;

providing the 3D test sample;
collecting data regarding a first segment of the 3D test sample by the biosensor array;
generating the DEP force to reposition the 3D sample relative to the biosensor array, including applying the AC signal to the first, second, third, fourth, fifth, sixth, seventh and eighth electrodes, and to a reference electrode positioned above the first, second, third, fourth, fifth, sixth, seventh and eighth electrodes and the biosensor array;
collecting data regarding a second segment of the 3D test sample by the biosensor array; and
combining the data regarding the first and second segments of the 3D test sample.
