A method for providing a plurality of hermetically sealed packages, including the steps of: providing at least two substrates including a first substrate and a second substrate, at least one of the at least two substrates being a transparent substrate, the two substrates being arranged directly adjoining each other or on top of one another, the transparent substrate defining a circumferential rim and an upper side of each package, the bottom of the package being defined by the second substrate, a respective contact area being defined at contact surfaces between the two substrates; sealing each functional area in a hermetically tight manner by bonding the two substrates along the contact area of each package; and dicing each package by a cutting step or a separating step, a particle jet being used to abrasively remove a material from the transparent substrate by the particle jet.

Hermetically sealed transparent cavity and package for same

A hermetically sealed package includes: a base substrate and a cover substrate which define at least part of the package, the base substrate and the cover substrate being hermetically sealed to one another by at least one laser bonding line, the at least one laser bonding line having a height perpendicular to its bonding plane, at least the cover substrate including a toughened layer at its surface, at least on a side opposite the at least one laser bonding line; and at least one functional area enclosed in the package.

Hermetically sealed, toughened glass package and method for producing same

A hermetically sealed package includes: at least one cover substrate and a substrate arranged so as to adjoin the at least one cover substrate, which together define at least part of the package, the at least one cover substrate being in a thermally prestressed state and bonded to the substrate adjoining the at least one cover substrate in a hermetically sealing manner by at least one laser bonding line, the at least one cover substrate being made of a material which has a different characteristic value of a coefficient of thermal expansion than the adjoining substrate and a thermal prestress is established in the package; and at least one functional area enclosed in the package.
