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: An inhibitor for selectively depositing a thin film may include a compound represented by Formula 1 below:




where, R1 is an aldehyde group, an amino group, a carbonyl group, a ketone group, a nitrile group, an acyl halide group, a substituted or unsubstituted C2 to C20 alkenyl group, or a substituted or unsubstituted C2 to C20 alkynyl group, R2 is a halogen atom, a substituted or unsubstituted C1 to C10 alkylhalide group, a substituted or unsubstituted C4 to C10 tertiary alkyl group, or a substituted or unsubstituted C1 to C10 alkylthio group, and n is an integer from 1 to 5. The inhibitor is adsorbed to a surface of a first layer but not adsorbed to a surface of a second layer. The first layer may include a metal-based material, and the second layer is different from the first layer and may include an insulating material.
