Abstract:
A method is provided that includes forming a first level above a substrate, forming a second level above the first level, and forming a third level above the second level. The first level includes a plurality of first elements having a first minimum pitch, the second level includes a plurality of second elements having a second minimum pitch greater than the first minimum pitch, and the third level includes a plurality of third elements having a third minimum pitch greater than the first minimum pitch. The second elements are disposed above and aligned with a first plurality of the first elements, and the third elements are disposed above and aligned with a second plurality of the first elements.
