Abstract:
1. A thin-film fabrication method by microplasma processing, comprising the steps of: disposing a raw material for thin-film fabrication in one or more narrow tubes (A) having a uniform inner diameter of 2 mm or less; introducing an inert gas and applying a high-frequency voltage to the one or more narrow tubes (A) to generate high-frequency plasma in the one or more narrow tubes (A); heating the raw material to evaporate the raw material while maintaining flow rate of plasma gas in the one or more narrow tubes (A) and maintaining the plasma gas temperature high; ejecting the evaporated material with the high-frequency plasma from the one or more narrow tubes (A) to spray it onto a substrate; heating the substrate with the ejected plasma; and depositing the evaporated material sprayed on the substrate during the ejecting step under atmospheric pressure.
