    摘要: This invention relates to a group of methods aimed to facilitate the start of a controlled thermal scoring, shearing or separation method applied to brittle materials. More or less all thermal scoring, shearing or separation methods have in common that the specific energy level inherent to this method remains constant over the path. Such energy level sufficient to control the propagation of a crack is insufficient to start the same.

    摘要: A limited portion of a surface of a glass substrate is removed by application of a laser beam on the limited portion of the glass substrate to thereby produce a glass structure according to the invention. The glass substrate contains at least one element such as titanium, iron, vanadium, bismuth, lead, thallium, tin, cerium, rhodium or cobalt capable of absorbing energy of the laser beam and has a threshold of not larger than 1.0 J/cm2 per laser beam pulse in terms of machining energy of the laser beam. When such a glass substrate 21 is used, a glass structure having a through-hole 61 or cavity optional in sectional shape can be formed by irradiation with the laser beam 10.
