    摘要: The present invention provides photoresist monomers, photoresist polymers derived from the same, processes for producing such photoresist polymers, photoresist compositions comprising such polymers, and processes for producing a photoresist pattern using such photoresist compositions. In particular, photoresist monomers of the present invention comprise a moiety of Formula 4: where R1, R2, R3 and R4 are those defined herein. Photoresist polymers of the present invention have a relatively high etching resistance, and therefore are useful in a thin resist process and a bilayer photoresist process. Moreover, photoresist polymers of the present invention have a high contrast ratio between an exposed region and a non-exposed region.

    摘要: A photoresist polymer for a top-surface imaging process by silylation (TIPS), and a photoresist composition comprising the same. The protecting group of the present photoresist polymer is selectively protected in an exposed region, and thus a hydroxyl group is generated. The hydroxyl group reacts with the silylation agent to cause a silylation process. Accordingly, when the photoresist film is dry-developed, the exposed region only remains to form a negative pattern. In addition, the present photoresist composition has excellent adhesiveness to a substrate, thus preventing a pattern collapse in forming a minute pattern. As a result, the present photoresist composition is suitable for a lithography process using light sources such as ArF (193 nm), VUV (157 nm) and EUV (13 nm).

    摘要: The present invention relates to a photoresist composition containing a photo radical generator, more specifically, to a photoresist composition which comprises (a) photoresist resin, (b) a photoacid generator, (c) an organic solvent and (d) a photo radical generator. The present photoresist composition reduces or prevents a sloping pattern formation due to a higher concentration of acid in the upper portion of the photoresist relative to the lower portion of the photoresist.
