METHOD FOR MANUFACTURING LAYERED-FILM-BEARING GLASS SUBSTRATE

摘要

A method for manufacturing a laminated film-coated glass substrate in which a laminated film is formed on a glass ribbon by a CVD method by means of a plurality of injectors disposed in an annealing furnace and the glass ribbon is cut, wherein the laminated film is formed at Tg+50° C. or lower and at least two layers of the laminated film are formed in a temperature range of Tg+50° C. to Tg. In addition, a temperature drop K1 per unit length of the glass ribbon in a temperature range where all layers of the laminated film are formed is 0° C./m
