    摘要: A method for manufacturing a semiconductor device using an immersion lithography process is disclosed. The immersion lithography process includes forming a photoresist film over an underlying layer of a semiconductor substrate; exposing the photoresist film to light without using an exposure mask; and performing an exposure process using an exposure mask. After exposure using the immersion lithography, a water mark generated from the exposure layer consumes a part of the acid of the exposure layer but the residual acid remains in the exposure layer to prevent generation of pattern defects such as T-top or pattern bridges.

    摘要: Disclosed herein is a top anti-reflective coating polymer represented by Formula 1, below: wherein R1 and R2 are independently hydrogen, fluoro, methyl or fluoromethyl; R3 is a C1-10 hydrocarbon or a C1-10 hydrocarbon in which the hydrogen atoms are partly replaced by fluorine atoms; and a, b and c, representing the mole fraction of each monomer, are in the range between 0.05 and 0.9. Because a top anti-reflective coating formed using the anti-reflective coating polymer of Formula 1 is not soluble in water, it can be applied to immersion lithography using water as a medium for a light source. In addition, because the top anti-reflective coating can reduce the reflectance from an underlying layer, the uniformity of CD is improved, thus enabling the formation of an ultra fine pattern.
