Abstract: Disclosed are a wavelet-based progressive fast recompression method and system for large-deformed mesh data. Given mesh data is compressed. The compressed mesh data is recompressed by propagating part of a deformed mesh to all meshes based on information extracted from the compressed data when the mesh data is deformed.

Abstract: A silicon compound, a composition, and associated methods, the silicon compound being represented by Chemical Formula (1): R1m(OR2)n(OR3)3-m-nSi—O—SiR4p(OR5)q(OR6)3-p-q,??Chemical Formula (1) wherein, in Chemical Formula (1), m, n, p, and q are each independently an integer of 0 to 3, and satisfy the following relations m+p?1, m+n?3, and p+q?3, R1 is a heterocyclic group, R4 is a heterocyclic group, a carbon saturated group, or a carbon unsaturated group, and R2, R3, R5, and R6 are each independently a hydrogen atom, a C1-C7 alkyl group, a C2-C7 alkenyl group, a C3-C7 cycloalkyl group, or a C3-C7 cycloalkenyl group.

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.
