Environmentally Friendly Glass

Product Name: AF 32® eco

Environmentally-friendly glass with high transmittance
AF 32® eco is an alkali-free flat glass manufactured by SCHOTT using a special down-draw method that the company developed. This makes it possible to manufacture products between 0.03 mm and 1.1 mm in thickness.

Its fire-polished surface results in a low roughness value. Furthermore, the coefficient of thermal expansion of AF 32® eco is the same as that of silicon. For this reason, it is perfectly suited for optical packaging material in the semiconductor industry. Due to its high transformation temperature, it can be used in high-temperature applications of up to approximately 600 °C.

AF 32® eco, the semiconductor packaging glass, is available in various wafer formats and is manufactured using eco-friendly refining agents instead of arsenic and antimony.
