    摘要: Disclosed is a method for manufacturing fine patterns of semiconductor devices using a double exposure patterning process for manufacturing the second photoresist patterns by simply exposing without an exposure mask. The method comprises the steps of: forming a first photoresist pattern on a semiconductor substrate on which a layer to be etched is formed; coating a composition for a mirror interlayer on the first photoresist pattern to form a mirror interlayer; forming a photoresist layer on the resultant; and forming a second photoresist pattern which is made by a scattered reflection of the mirror-interlayer and positioned between the first photoresist patterns, by exposing the photoresist layer to a light having energy which is lower than a threshold energy (Eth) of the photoresist layer without an exposure mask, and then developing the same.

    摘要: An acid-amplifier having an acetal group and a photoresist composition including the same, are disclosed. The acid-amplifier produces an acid (second acid) during a post-exposure-bake (PEB), which is induced by an acid (first acid) generated from a photo-acid generator (PAG) at the exposure process so that a line edge roughness (LER) of the photoresist pattern and photoresist energy sensitivity are improved. The acid-amplifier has a structure of following Formula 1. in Formula 1, R is C4˜C20 mono-cyclic or multi-cyclic saturated hydrocarbon, R1 is C1˜C10 linear hydrocarbon, C1˜C10 perfluoro compound or C5˜C20 aromatic compound, Ra and Rb are independently hydrogen atom or C1˜C4 saturated hydrocarbon and A is independently oxygen atom (O) or sulfur atom (S).
