Wafer to wafer alignment which includes a first semiconductor wafer and a second semiconductor wafer. The first and second semiconductor wafers have selectively-activated alignment arrays for aligning the first semiconductor wafer with the second semiconductor wafer. Each of the alignment arrays include an alignment structure which includes an antenna connected to a semiconductor device. The antenna in each of the alignment arrays is selectively activated to act as a charge source or as a charge sensing receptor. The alignment arrays are located in the kerf areas of the semiconductor wafers. The semiconductor wafers are aligned when the charge sources on one semiconductor wafer match with the charge sensing receptors on the other semiconductor wafer.
