    Abstract: A resist compound is represented by Formula 1:




    wherein R1 is an alkyl group having 1 to 12 carbon atoms, an alkenyl group having 1 to 12 carbon atoms, or a hydrocarbon ring group having 3 to 12 carbon atoms, and A bonded to R1 is O or NR2, wherein R2 is hydrogen, an alkyl group having 1 to 12 carbon atoms, an alkenyl group having 1 to 12 carbon atoms, or a hydrocarbon ring group having 3 to 12 carbon atoms. A resist composition includes the resist compound and an organic solvent. A method for forming a resist pattern includes forming a resist layer by applying the resist composition including the resist compound on a substrate, irradiating light onto the resist layer to provide an irradiated resist layer, and developing the irradiated resist layer to form a resist pattern.

    Abstract: Silicon compounds may be represented by the following formula: Each of Ra, Rb, and Rc may be a hydrogen atom, a halogen atom, a C1-C7 alkyl group, an amino group, a C1-C7 alkyl amino group, or a C1-C7 alkoxy group, Rd may be a C1-C7 alkyl group, a C1-C7 alkyl amino group, or a silyl group represented by a formula of *—Si(X1)(X2)(X3). Each of X1, X2, and X3 may be a hydrogen atom, a halogen atom, a C1-C7 alkyl group, an amino group, a C1-C7 alkyl amino group, or a C1-C7 alkoxy group, and * is a bonding site. In some embodiments, when Rb is the C1-C7 alkyl amino group and Rd is the C1-C7 alkyl group, Rb may be connected to Rd to form a ring. To manufacture an integrated circuit (IC) device, a silicon-containing film may be formed on a substrate using the silicon compound of the formula provided above.

    Abstract: Photoresist compositions may include a photosensitive polymer, a photoacid generator (PAG), and a solvent. The photosensitive polymer may include a first repeating unit having a structure of Formula: wherein R1 is an oxygen atom or a methyl group, and R2 is a nitrobenzyl-based photo-labile protecting group. In methods of manufacturing an integrated circuit (IC), a photoresist film is formed on a lower film by using the photoresist composition including the photosensitive polymer, the PAG, and the solvent. A hydroxystyrene repeating unit is deprotected in a first area of the photoresist film by exposing the first area of the photoresist film to light, and thus, the nitrobenzyl-based photo-labile protecting group is separated from the hydroxystyrene repeating unit and a sensitizer is generated from the hydroxystyrene repeating unit. The exposed first area is removed using a developer.
