    摘要: A method of defining patterns in a small pitch is described. A substrate having a target layer thereon is provided, and two laterally separate reflective structures with two opposite sidewalls are formed over the target layer. A photoresist layer is formed over the target layer between the two opposite sidewalls. An exposure step is performed allowing light to be reflected by the two opposite sidewalls in the lateral direction, wherein the two opposite sidewalls are spaced by a distance to cause the reflected light to produce a periodical intensity distribution in the photoresist layer in the lateral direction.

    摘要: A method and system to form openings comprises an exposure apparatus and a mask to selectively expose a semiconductor substrate to a radiation source to transfer assist feature patterns and primary feature patterns to a photosensitive layer of the substrate. A heating apparatus eliminates the assist features by heating the substrate and shrinking the primary features. The patterns on the photosensitive layer are transferred to a layer under the photosensitive layer by an etching process.
