Abstract (en)
[origin: WO2021009297A1] The invention relates to a hermetically sealed housing comprising a base substrate and a cover substrate, which form at least one part of the housing, at least one functional region surrounded by the housing, wherein at least the cover substrate preferably comprises a glass-type material, wherein the base substrate and the cover substrate are joined in a hermetically sealed manner with at least one laser bonding line, wherein the laser bonding line has a height HL perpendicular to its connection plane, wherein at least the cover substrate has a hardened layer on the surface on the side opposite the laser bonding line, preferably a chemically hardened layer, wherein the hardened layer preferably exerts a compressive stress on the cover substrate.
