Patent ID: 7371431

Claim:
A method of producing smaller, sheet glass plates having a predetermined geometry and lateral dimensions in the millimeter range by separation of the smaller, sheet glass plates from a larger uncoated sheet glass plate, said method consisting of the steps of: a) imprinting the larger uncoated sheet glass plate on one side with a joining material in accordance with a joining zone geometry of the smaller, sheet glass plates; b) specifying dividing lines on a back side of the larger uncoated sheet glass plate opposite from the one side on which the joining material is provided; c) prior to the separating of the smaller, sheet glass plates from the larger uncoated sheet glass plate, scribing the larger uncoated sheet glass plate along the dividing lines on the back side of the larger uncoated sheet glass plate to a predetermined depth using a laser beam to form a plurality of fissures on the back side; and d) after the scribing with the laser beam, separating the smaller, sheet glass plates from the larger uncoated sheet glass plate by breaking the larger uncoated sheet glass plate apart along the fissures.
