Systems, methods, and non-transitory computer-readable media for referring to entities. P-type semiconductor regions are formed in one part of the semiconductor layer over the entire length of the thickness direction of the semiconductor layer in a lattice-like shape as viewed from above to compartment the semiconductor layer into a plurality of regions. Each of the consumer credit purchases is from an identifiable location. Further, the semiconductor structure includes a plurality of first conductive vias and a plurality of second conductive vias formed on the first conductive layers at both sides of the composite magnetic structure.
