Abstract:
1. A method of continuously forming a thin film comprising the steps of: moving a glass substrate with a thin continuous strip shape having a constant db/2(d+b), where d is a thickness thereof in a range from 30 μm to 300 μm and b is a width thereof in a cross section thereof, within a range from 0.015 to 0.15 through a film depositing region, in which a reaction gas is supplied and a temperature is controlled to be higher than 1,050° C., in a suspended state in the reaction gas for a period of time between 0.1 second and 0.25 second, so that the glass substrate is heated, and the reaction gas is a mixed gas of H moving continuously the glass substrate, immediately after the glass substrate passes through the film depositing region, to pass through a cooling region in which a temperature is lower than 900° C. in a suspended state, so that the glass substrate is cooled and the thin film formed of a component of the reaction gas is formed on the glass substrate.
