RESIDUAL STRESS REDUCTION METHOD OF GLASS SUBSTRATE AND RESIDUAL STRESS REDUCTION DEVICE OF GLASS SUBSTRATE

摘要

To reduce a residual stress of a glass substrate which is integrated with a resin or the like.SOLUTION: A residual stress reduction method of a glass substrate G includes a laser beam irradiation step of irradiating a plurality of portions with a high residual stress of a glass substrate G respectively by a laser beam for a predetermined time, and thereby heating the portions.SELECTED DRAWING: Figure 5
