Claim 15:
16. The device of claim 13, further comprising:
a second filler that fills the second wells and covers portions of the second dielectric layer over second upper surfaces of the second polymer projections,
a plurality of third polymer projections on the second filler, wherein the plurality of second polymer projections have spaces therebetween that expose the second filler, and wherein each third polymer projection has a third upper surface that is substantially parallel to the substantially planar top surface and sides extending from the second filler to the third upper surface, and
a third dielectric layer conformally covering the plurality of third polymer projections and second filler in the spaces between the third polymer projections, wherein the third dielectric layer forms third side walls along the sides of the third polymer projections and defining third wells extending into spaces between the third side walls so that the third wells extend below third upper surfaces of the third polymer projections.
