Beschreibung
Zusammenfassung:	A substrate stack and an enclosure is shown, comprising at least a base substrate and a cover substrate, which constitute at least a part of the enclosure. A function zone may be situated such that it is circumferentially enclosed in the enclosure. At least the cover substrate comprises preferably a glass or glass-like material. The base substrate and the cover substrate are hermetically welded by means of at least one laser weld line, where the laser weld line comprises a height HL in a direction perpendicular to its connecting plane, and wherein the mechanical stress in the at least one laser weld line is reduced, thus improving the mechanical stability of the enclosure.
