Abstract:
A thin-film fabrication apparatus comprising:a vacuum vessel;at least one spray nozzle provided within the vacuum vessel for each thin-film composition material that is to be sprayed;a substrate having a surface on which the thin-film composition material is deposited;measuring means for measuring a substrate temperature;heating means for heating the substrate;control means for controlling the heating means;evacuation means for evacuating the vacuum vessel; anda removable exothermic film provided on another surface of the substrate opposite the surface on which the thin-film composition material is deposited;said control means controlling the heating means to heat the substrate within a control temperature range having a lower limited defined as a temperature that exceeds a lowest temperature of a group of temperatures (1) to (3) selected depending on constituent components of the thin-film composition material used, and an upper limit defined at a temperature that does not exceed a lowest heat decomposition initiation temperature of said thin film composition material components, said group of temperatures being:(1) in the case of a thin-film composition material that includes a component containing a thermoplastic high-molecular compound, a melt initiation temperature of the component containing the thermoplastic high-molecular compound,(2) in the case of a thin-film composition material that contains an organic or inorganic high-molecular compound precursor, a polymerization initiation temperature, and(3) in the case of a thin-film composition material that contains an organic or inorganic cross-linking agent or bridged compound, a temperature at which a cross-linking reaction is initiated.
