Verfahren zum Schneiden von Glas

摘要

A first laser beam ( 2 ) and a second laser beam ( 3 ) composed of an ultraviolet laser are irradiated from a side of a second glass member ( 5 b), allowing the first laser beam ( 2 ) to pass through the second glass member ( 5 b) so as to condense the first laser beam ( 2 ) on the first glass member ( 5 a) to form a first scribe line ( 14 ), condensing the second laser beam ( 3 ) on the second glass member ( 5 b) to form a second scribe line ( 15 ), and applying a break force to the first scribe line ( 14 ) and the second scribe line ( 15 ) to cut the glass.
