  • Publication number: 20150162195
    Abstract: In a method of manufacturing a semiconductor device, a blend solution that includes a block copolymer and an adsorbent is prepared. The block copolymer is synthesized by a copolymerization between a first polymer unit and a second polymer unit having a hydrophilicity greater than that of the first polymer unit. The adsorbent on which the block copolymer is adsorbed is extracted. The block copolymer is separated from the adsorbent. The block copolymer is collected. The block copolymer may be used to form a mask on an object layer on a substrate and the mask used to etch the object layer.
