    摘要: System and method for enhancing optical lithography methodology for hole patterning in semiconductor fabrication are described. In one embodiment, a photolithography system comprises an illumination system for conditioning light from a light source, the illumination system producing a three-pore illumination pattern; a reticle comprising at least a portion of a pattern to be imaged onto a substrate, wherein the three-pore illumination pattern produced by the illumination system is projected through the reticle; and a projection lens disposed between the reticle and the substrate.

    摘要: Contrast enhancing exposure apparatus and method for use in semiconductor fabrication are described. In one embodiment, a method for forming a pattern on a substrate, wherein the substrate includes a photoresist layer comprising photoacid generators (“PAGs”) and photobase generators (“PBGs”), is described. The method includes dividing the pattern into two component patterns; exposing the photoresist layer of the substrate to UV light through a first mask corresponding to a first one of the component patterns; subsequent to the exposing the photoresist layer of the substrate to UV light through the first mask, exposing the photoresist layer of the substrate to UV light through a second mask corresponding to a second one of the component patterns, wherein the PAGs and PBGs disposed in areas of the photoresist layer that have been exposed to UV light at least twice are activated and wherein the activated PAGs neutralize the activated PBGs in areas of the photoresist layer that have been exposed to UV light at least twice.
