Abstract:
1. A laser-scribing system for structuring substrates, said laser-scribing system comprising: a platform for accommodating at least one substrate; at least one support body including at least one planar stator, and said support body being fitted in spaced-apart relationship to said platform; at least one movable unit associated with said support body, said movable unit including at least one planar armature configured to perform movements both in a first direction x and in a direction opposite to the first direction −x as well as in a second direction y, normal to the first direction x, and in a direction opposite to the second direction −y; and one or more laser devices with at least one laser beam are mounted on said planar armature, which creates scribing tracks on said substrate by said laser beam in the first direction x and in the direction opposite to the first direction −x; wherein said support body is fitted in relationship to said platform in such a manner that said associated movable unit performs on said support body linear movements in the first direction x and in the direction opposite to the first direction −x, and that said movable unit represented by said planar armature, jointly with said laser device, has a mass which is less than a mass of said platform, jointly with said substrate, such that thereby an increase of a processing rate is attained, vibrations are reduced and, accordingly, accuracy of the scribing tracks is increased.
