摘要:
A semiconductor device having an insulating film comprising a fluorine-doped carbon film having experienced a thermal history under a temperature of 420°C or less, characterized in that the fluorine-doped carbon film has a hydrogen atom content of 3 atomic % or less before the experience of the thermal history.
摘要:
A gas for plasma reaction which comprises a C5-6 chain perfluoroalkyne, preferably perfluoro-2-pentyne. This gas is suitable for use in the formation of a fine pattern by dry etching, formation of a thin film by CVD, or ashing. It is synthesized by contacting a dihydrofluoroalkane compound or monohydrofluoroalkene compound with a basic compound.
