Abstract:
A method for fabricating a microelectronics fabrication comprising:providing a substrate employed within a microelectronics fabrication;forming horizontally spaced over the substrate a plurality of patterned microelectronics structures;forming over the substrate and the plurality of patterned microelectronics structures a microelectronics layer, the microelectronics layer having a first region of the microelectronics layer interposed between the plurality of patterned microelectronics structures and a second region of the microelectronics layer not interposed between the plurality of patterned microelectronics structures; andprocessing through a grazing angle method the microelectronics layer, where the grazing angle method processes substantially all of the second region of the microelectronics layer without substantially processing the first region of the microelectronics layer, wherein:the grazing angle method employs a grazing angle charged particle beam formed by extraction of charged particles from a radiation beam source remote from the substrate; andthe grazing angle charged particle beam is spirally constrained within the vicinity of the substrate by an extrinsic magnetic field substantially perpendicular to the substrate.
