Abstract

Fabrication of a circuit structure is facilitated, in which a first exposure of a multi-layer structure is performed using a first mask, which defines positioning of at least one edge of an element to be formed above a substrate of the multi-layer structure. A second exposure of the multi-layer structure is performed using a second mask, which defines positioning of at least one other edge of the element. At least some material of the multi-layer structure is removed using, at least in part, the defined positioning of the at least one edge and the at least one other edges of the element, to form the element above the substrate. In some examples, multiple elements are formed, the multiple elements being hardmask elements to facilitate an etch process to etch a substrate material.
