<p>PROBLEM TO BE SOLVED: To provide a discrete units method for glass-substrate heat treatment that can uniformly heat-treat a film-coated surface of a glass substrate which may be coated with different films and may have different structures through' a variety of processes, and also provide an apparatus for the discrete units method. SOLUTION: This glass-substrate heat treatment comprises placing a glass substrate one surface of which is coated with a substance to be heat-treated on a hot plate, and heating the surface of the glass substrate placed on the hot plate uniformly to a high temperature in such a way that the glass substrate is placed with its coated surface upward on the hot plate fitted with spacers for providing a clearance between the glass plate and the hot plate.</p> |
