Abstract: 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.

Abstract: An improved measurement method and a corresponding measurement device are provided that measure the edge strength of plate-shaped elements made of brittle-fracture material. For this purpose, a long sample is drawn apart at the short edges, wherein the force transmission points lie next to the center of gravity of the base surface of the sample.

Abstract: A glass ribbon in the form of a glass roll is provided that is optimized with respect to the requirements of a long service life and at the same time compact dimensions. A bending radius on the inner side of the thin glass roll is determined by performing breakage tests on samples of the glass material, statistical parameters are determined on the basis of the breakage tests, and the statistical parameters are converted into a range of bending radii which meet the requirements on service life and the most compact dimensions possible of the thin glass roll.
