Title:
METHOD FOR MANUFACTURING GLASS SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2016/152932
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method for manufacturing a glass substrate which is capable of efficiently improving the cleanliness of the surfaces of the glass substrate. This method for manufacturing a glass substrate comprises: a cutting step of cutting the glass substrate; an edge machining step of machining cut edges which are cut surfaces of the glass substrate cut in the cutting step; and a surface treatment step of treating the main surface of the glass substrate cut in the cutting step. In the edge machining step, the shape of the cut edges is machined while a grinding fluid is fed to the cut edges. In the surface treatment step, an alkaline solution having a pH of less than 10 is applied onto the main surface, and the surface treatment step is performed at the same time as the edge machining step.
