Abstract (en)
[origin: WO2021122847A1] The invention relates to a substrate in the form of a glass plate in which recesses are formed which extend through the entire thickness of the substrate and of which the cross-sections at opposite ends are open in the plane of the mutually opposing surfaces of the glass plate. The recesses therefore form through holes through the glass plate and have an internal diameter from 5 to 1000 μm.
