    摘要： The present invention provides an additive for a photoresist composition for a resist flow process. A compound of following Formula 1 having low glass transition temperature is added to a photoresist composition containing a polymer which is not suitable for the resist flow process due to its high glass transition temperature, thus improving a flow property of the photoresist composition. As a result, the photoresist composition comprising an additive of Formula 1 can be used for the resist flow process. wherein, A, B, R and R′ are as defined in the specification of the invention.

    摘要： The present invention provides photoresist polymers, processes for producing the same, photoresist compositions comprising such polymers, and processes for producing a photoresist pattern using such photoresist compositions. In particular, photoresist polymers of the present invention comprise a moiety of the Formula: 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 thin resist processes and bilayer photoresist processes. Moreover, photoresist polymers of the present invention have a high contrast ratio between the exposed region and the non-exposed region.
