Abstract:
Technologies for inverting lithographic patterns are described. In some embodiments the technologies include a method for inverting a lithographic pattern of hole precursors, so as to form one or more high aspect ratio structures on or in a surface of a substrate.

Claim (Index 26):
A method for forming high aspect ratio structures, comprising:\n providing a modified workpiece, said modified workpiece comprising a substrate, an etch stop layer on a surface of the substrate, and at least one blind hole extending through said etch stop layer and partially into said substrate, said at least one blind hole located at a first position relative to said substrate; forming a second hardmask material within said at least one blind hole; and forming a high aspect ratio structure beneath said second hardmask material at least in part by selectively removing regions of said etch stop layer proximate said second hardmask material and at least a portion of the substrate below said regions of said etch stop layer; wherein the high aspect ratio structure is formed at a second location relative to said substrate, the second location corresponding to the first location.
