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.

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).

摘要:
A photoresist polymer having a spiro cyclic ketal group, and a photoresist composition including the same is disclosed. The photoresist polymer and the photoresist composition can improve the resolution and the process margin due to its low activation energy of the deprotection reaction of the spiro cyclic ketal group, and can produce fine photoresist patterns due to its low PEB (Post Exposure Baking) temperature sensitivity.
