Abstract

A method for processing a carrier accordance with various embodiments may include: forming a structure over the carrier, the structure including at least two adjacent structure elements arranged at a first distance between the same; depositing a spacer layer over the structure, wherein the spacer layer may be deposited having a thickness greater than half of the first distance, wherein the spacer layer may include electrically conductive spacer material; removing a portion of the spacer layer, wherein spacer material of the spacer layer may remain in a region between the at least two adjacent structure elements; and electrically contacting the remaining spacer material.
