Abstract
The present disclosure relates to a method for preparing and/or performing the separation of a substrate element into at least two substrate sub-elements along a separation face and a substrate sub-element which is manufactured and/or can be manufactured in particular by use of the method according to the disclosure.
Claims20
Method for preparing and/or performing the separation of a substrate element into at least two substrate sub-elements along a separation face, comprising the steps of:
- providing the substrate element, wherein the substrate element comprises a substrate body, wherein the substrate body comprises a substrate material;
- and
- controlling a line focus within the substrate body so that the substrate material of the substrate body is at least locally removed and/or displaced along the separation face at least section-wise;
- wherein the line focus represents a focus of a light beam;
- wherein the light beam is formed at least in the area of the line focus in the form of a light beam with an asymmetrical beam supply.
2 more elements
A substrate sub-element,
- comprising at least one body which comprises at least one glass material, glass ceramic material, and/or silicon, and has at least one side face,
- wherein the side face has at least section-wise a height-modulated surface;
- wherein the side face has at least section-wise a surface roughness and a variation of the surface as a result of the surface roughness is between 1 and 5 orders of magnitude less than a variation of the surface as a result of the height modulation.
