Patent number: 11534754Abstract: A method for producing a cavity in a substrate composed of hard brittle material is provided. A laser beam of an ultrashort pulse laser is directed a side surface of the substrate and is concentrated by a focusing optical unit to form an elongated focus in the substrate. Incident energy of the laser beam produces a filament-shaped flaw in a volume of the substrate. The filament-shaped flaw extends into the volume to a predetermined depth and does not pass through the substrate. To produce the filament-shaped flaw, the ultrashort pulse laser radiates in a pulse or a pulse packet having at least two successive laser pulses. After at least two filament-shaped flaws are introduced, the substrate is exposed to an etching medium which removes material of the substrate and widens the at least two filament-shaped flaws to form filaments. At least two filaments are connected to form a cavity.Type: GrantFiled: April 26, 2019Date of Patent: December 27, 2022Assignee: Schott AGInventors: Andreas Ortner, Andreas Roters, Hauke Esemann, Markus Heiss-Chouquet, Fabian Wagner, Laura Brueckbauer, Stephanie Mangold, Vanessa Hiller

Publication number: 20190329252Abstract: A method for the production of microfluidic cells using a disc-shaped glass element is provided. The disc-shaped glass element has a thickness of at most 700 micrometers is structured in such a way that it has at least one opening. The opening connects the two opposite-lying, parallel side faces of the glass element. The side faces are attached to a glass part so that the opening is sealed by the two glass parts to form a microfluidic cell having a cavity enclosed therein. The cavity is suitable for the conveyance of fluids. The attachment of the glass element to at least one of the two glass parts is produced by an adhesive that is applied onto the side face of the glass element. During application of the adhesive, the at least one opening in the glass element is left free of adhesive.Type: ApplicationFiled: April 26, 2019Publication date: October 31, 2019Applicant: SCHOTT AGInventors: Hauke Esemann, Stephanie Mangold, Andreas Roters, Andreas Ortner, Markus Heiss-Chouquet, Fabian Wagner, Vanessa Hiller, Laura Brueckbauer
