Low-Alkali Thin Film Glass Substrate for Electronic Components

Alkali-free alumina-borosilicate thin glass:The advanced flat alumina-borosilicate glass AF 32® eco is alkali-free in synthesis, It is fabricated by the down-draw manufacturing process. This technology was developed by Germany and allows the production of very thin glass thicknesses with very high quality. AF 32® eco features a low micro-roughness of typically < 1 nanometer (RMS) and has a coefficient of thermal expansion of 3,2 x 10-6 that is very close to the one of silicon. This property opens up a wide range of glass wafer applications in the semiconductor industry. Wafers used for MEMS-applications (micro-electro-mechanical systems) are often made from AF 32® eco-glass materials.Special Properties
