Special glasses from the system Li2O-Al2O3-SiO2 are microstructurable by a UV-lithographic process. If you use the basic process it is possible to prepare two dimensional through structures in a glass wafer.

A new exposure technique allows a 3D etching process in photosensitive glass. A pattern with a defined width and mesh are made in a chromium layer on vitreous silica. By use of these mask a different UV-intensity results in the glass during the exposure. Due to the different intensities, the exposure of various depths is possible.

The advantage of this technology is the production of structures with two dimensional free design, various depths and a defined angle of walls in one process.
