    摘要: The present invention relates to a semiconductor device using a copolymer-containing photoresist, and a process for manufacturing the same. As a norbornene derivative (monomer) having a hydrophilic group is synthesized and introduced to the backbone chain of a polymer, the polymer according to the present invention has excellent etching resistance and heat resistance, which are the characteristic points of alicyclic olefin structure, and provide excellent resolution due to prominent enhancement of adhesiveness resulted from introducing a hydrophilic group (—OH).

    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.
