Compositions and methods to fabricate a photoactive substrate suitable for shaped glass structures

摘要

This invention provides an inexpensive and rapid method for fabricating a high-anisotropic-etch ratio, shaped glass structures using a novel photosensitive glass composition. Structures of the photosensitive glass may include micro-channels, micro-optics, microposts, or arrays of hollow micro-needles. Furthermore, such shaped glass structures can be used to form a negative mold for casting the shape in other materials.
