Abstract
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.
