Development of heat resistant polyphenol compounds applied to the Spin-On Carbon Hardmask

摘要

In this paper, we report the development of a new polyphenol, NF7177, applied to the Spin-On Carbon Hardmask and the thermosetting properties. The new polyphenol derivatives were easily synthesized by the condensation of aldehydes and dihydroxybiphenyl compounds. We found new polyphenol NF7177 was showed the good applicability to the raw material for the Spin-On Carbon Hardmask. It was indicated that the heat resistance of NF7177 was due to closslinking based on dehydration reaction. Furthermore the thermosetting properties seem to be depend on the number and position of OH group.
