Claim:
A layered three-dimensional structure having a minimum feature size associated with the formation of features on each layer, the layered three-dimensional structure comprising: a first layer having a frame structure defining an array of first openings, wherein each first opening is at least as large as the minimum feature size; and a second layer having a frame structure defining an array of second openings, wherein each second opening is at least as large as the minimum feature size, wherein the second layer is positioned adjacent to and adhered to the first layer, wherein at least some openings in the array of second openings are positioned to partially overlap at least some openings in the array of first openings to define an array of third openings formed from the array of first openings and the array of second openings, and wherein at least a portion of the openings in the third array of openings have effective widths that are less than the minimum feature size, and wherein a plurality of the first openings have a first size, wherein a plurality of the second openings that partially overlap the plurality of first openings have a size substantially the same as the first size.
