FOTURAN® II

SCHOTT FOTURAN® II is a photo-structurable glass produced in a continuous melting process to achieve outstanding homogeneity. After UV exposure and temperature processes, fine and uniform structures can be formed, which can be used in areas that require the characteristics of both glass-ceramics and fine structures.

Extremely fine, advanced structuring

FOTURAN® II is a photo-structurable glass, with areas crystallized by UV exposure and heat treatment able to be etched to produce exceptionally fine structuring with a high aspect ratio – in customized 3D forms if required. After a second exposure and tempering process, FOTURAN® II can also be transformed into an opaque glass-ceramic.

Adaptable for semiconductor packaging

Finely structured FOTURAN® II substrates have a very useful role in semiconductor and packaging processes. Structuring can be achieved without the need for photo-resist and can be used with equipment commonly available in the semiconductor industry, minimizing the work and extra costs involved.

Excellent technical properties

A highly impressive array of technical attributes provides FOTURAN® II with the characteristics to suit a number of applications. It is a highly uniform glass-ceramic thanks to the continuous melting process of manufacturing, while it offers a low TTV, low roughness and low defect rate at a range of thicknesses, including extremely thin wafer form. Structuring with FOTURAN® II wafer is simple using standard semiconductor equipment, with these structures offering uniform properties and performance reliability.
