Patent ID: 11817316

Abstract:
Coating compositions comprise: a B-staged reaction product of one or more compounds comprising: a core chosen from C6-50 carbocyclic aromatic, C2-50 heterocyclic aromatic, C1-20 aliphatic, C1-20 heteroaliphatic, C3-20 cycloaliphatic, and C2-20 heterocycloaliphatic, each of which may be substituted or unsubstituted; and two or more substituents of formula (1) attached to the core: wherein: Ar1 is an aromatic group independently chosen from C6-50 carbocyclic aromatic and C2-50 heteroaromatic, each of which may be substituted or unsubstituted; Z is a substituent independently chosen from OR1, protected hydroxyl, carboxyl, protected carboxyl, SR1, protected thiol, —O—C(═O)—C1-6 alkyl, halogen, and NHR2; wherein each R1 is independently chosen from H, C1-10 alkyl, C2-10 unsaturated hydrocarbyl, and C5-30 aryl; each R2 is independently chosen from H, C1-10 alkyl, C2-10 unsaturated hydrocarbyl, C5-30 aryl, C(═O)—R1, and S(═O)2—R1; x is an integer from 1 to the total number of available aromatic ring atoms in Ar1; and * denotes the point of attachment to the core; provided that when the core comprises an aromatic ring, no substituents of formula (1) are in an ortho position to each other on the same aromatic ring of the core; and one or more solvents, wherein the total solvent content is from 50 to 99 wt % based on the coating composition. Coated substrates formed with the coating compositions and methods of forming electronic devices using the compositions are also provided. The compositions, coated substrates and methods find particular applicability in the manufacture of semiconductor devices.
