Abstract
Disclosed is a method for structuring a flat substrate consisting of a glass-type material. The invented method is distinguished by a combination of the following steps: providing a semiconductor flat substrate consisting of a semiconductor material, structuring at least one surface of said semiconductor flat substrate to obtain recesses in said surface, connecting said surface of said semiconductor flat substrate to said glass-type flat substrate, with said structured surface of said semiconductor flat substrate being connected to a surface of said glass-type flat surface at least partially covering the same,tempering said connected flat substrates in such a manner that at least a part of the said glass-type material flows into said recesses of said structured surface of said semiconductor flat substrate,removing material at least from the resolidified glass-type flat substrate in such a manner that said glass-type flat substrate assumes a surface which is flush with said structured surface of said semiconductor flat substrate.
