Abstract: A method includes forming mask patterns spaced apart from each other by at least one opening on an etch target layer, filling the opening with a block copolymer material including first and second polymer blocks of different properties, and annealing the block copolymer material to form first patterns and second patterns, the first patterns in contact with facing sidewalls of adjacent ones of the mask patterns, respectively, and at least one of the second patterns between the first patterns. The first patterns include the first polymer blocks and the second patterns include the second polymer blocks.

Abstract: A photoresist composition includes a photosensitive polymer including a polymer chain and at least one first functional group coupled to the polymer chain, and a photoacid generator. The first functional group has a structure represented by the following Chemical Formula 1, where R1 is one of an alkyl group having a carbon number of 1 to 20 and an aryl group having a carbon number of 1 to 20, and R2 is one of —H, —F, —Cl, —Br, an alkyl group having a carbon number of 1 to 20, and an aryl group having a carbon number of 1 to 20.

Abstract: The inventive concepts provide methods of purifying a block copolymer and methods of forming a pattern using the same. The purifying method is performed using a first adsorbent. The first adsorbent has adsorbability with respect to a first polymer block having a molecular weight equal to or greater than a first average molecular weight. The purifying method further includes purifying a synthesized polymer using a second adsorbent. The second adsorbent interacts with a second polymer block.
