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.

Method for preparing and/or performing the separation of a substrate element and substrate sub-element

A method for preparing and/or carrying out the structuring of a predetermined or predeterminable distinguished surface of a substrate body having a substrate material includes exposing the substrate material in at least one curved effective area to an electromagnetic field which in each of the at least one curved effective area causes a non-linear interaction between the electromagnetic field and the substrate material, and thus at least partially influencing the substrate material arranged in the curved effective area. After the structuring of the distinguished surface the distinguished surface has at least in certain areas at least one first curved progression which is at least partially determined and/or influenced by the curved shape of the at least one curved effective area. The nonlinear interaction causes at least one nonlinear absorption of the electromagnetic field in the substrate material.

Method of surface structuring a substrate body and substrate body

A method of structuring a glass element having a first side face and a second side face is provided. The method includes the steps of: producing a filament-shaped flaw in the glass element with a pulsed laser beam along a focus line; etching to remove glass in the filament-shaped flaw to form a wall extending from the first side face towards the second side face, the wall having a boundary line that is tapered at a vertex between the wall and the first side face with a taper angle with respect to a perpendicular of the first side face; and adjusting the taper angle by controlling a feature of the focus line. The feature is selected from a group consisting of a position of the focus line, a length of the focus line, an intensity distribution of the focus line, and any combinations thereof.

Method of structuring a glass element and structured glass element produced thereby

The present disclosure relates to a method for at least section-wise separating a glass element into at least two glass sub-elements along a separation face and a glass sub-element which is manufactured and/or can be manufactured in particular by the method according to the disclosure.
