Abstract:
1. A silicon structure comprising: a silicon substrate having a primary surface and at least one supporting column, a top of the supporting column being higher than all other surfaces of the silicon substrate, and all surfaces of the supporting column are at least substantially non-curved; and an on-substrate structure including a silicon compound film and formed on said silicon substrate, the on-substrate structure supported by the supporting column, wherein the supporting column has a base, the top, and one or more side surfaces, the base extending from the primary surface of the silicon substrate, the top making direct contact with the on-substrate structure, the base having a width greater than a width of the top, the side surfaces joining the top with the base, the side surfaces continually tapering from a greatest width at the base to a smallest width at the top such that the smallest width of the side surfaces at the top is smaller than all other widths of the side surfaces, and wherein said on-substrate structure comprises:
