Abstract

Official abstract text for this publication.

Provided is a compound containing a phenolic hydroxy group which has excellent heat resistance, a resist composition which has excellent thermal decomposition resistance, optical sensitivity and resolution, and a composition for a resist underlayer coating which has excellent thermal decomposition resistance and dry etching resistance. The compound containing a phenolic hydroxy group has a molecular structure represented by Structural Formula (1) below: wherein R 1 is a hydrogen atom, an alkyl group or an aryl group, n is an integer of 2 to 10, R 2 is any one of an alkyl group, an alkoxy group, an aryl group, an aralkyl group and a halogen atom, m is an integer of 0 to 4, and when m is 2 or greater, a plurality of R 2 's may be the same as or different from each other and may be bonded to either one of two aromatic rings of the naphthylene skeleton.

First claim

Opening claim text (preview).

The invention claimed is: 1. A calix[2-10]arene compound which is obtained by reacting a 1,6-dihydroxynaphthalene compound with formaldehyde in the presence of a basic catalyst; wherein the 1,6-dihydroxynaphthalene is unsubstituted or substituted by any of alkyl, alkoxy, aryl, aralkyl or halogen. 2. A photosensitive composition comprising the calix[2-10]arene compound according to claim 1 and a photosensitizer. 3. A resist coating formed by coating the photosensitive composition of claim 2 . 4. A curable composition comprising the calix[2-10]arene compound according to claim 1 and a curing agent. 5. A cured product obtained by curing the curable composition of claim 4 . 6. A resist underlayer coating formed by coating and curing the curable composition of claim 4 . 7. A calix[2-10]arene compound which is obtained by reacting a 1,6-dihydroxynaphthalene compound with an aliphatic aldehyde compound having 2 or more carbon atoms or an aromatic aldehyde compound, in the presence of an acid catalyst; wherein the 1,6-dihydroxynaphthalene is unsubstituted or substituted by any of alkyl, alkoxy, aryl, aralkyl or halogen. 8. A photosensitive composition comprising the calix[2-10]arene compound according to claim 4 and a photosensitizer. 9. A resist coating formed by coating the photosensitive composition of claim 8 . 10. A curable composition comprising the calix[2-10]arene compound according to claim 7 and a curing agent. 11. A cured product obtained by curing the curable composition of claim 10 . 12. A resist underlayer coating formed by coating and curing the curable composition of claim 10 .
