Chemical Composition of Schott Borofloat Borosilicate Glass

The performance requirements for glass wafers used for anodic bonding or as carrier wafers in wafer thinning processes are mainly determined by their ability to perfectly match those of the silicon wafer to which they shall be permanently or temporarily bonded. Well-adapted thermal expansion behavior is as important as excellent flatness and process robustness. BOROFLOAT glass wafers provide such outstanding material properties along with exceptionally high UV transmission a special requirement for high speed laser de-bonding processes.

Silicon wafers (P type and N type) are also available from MSE Supplies.

BOROFLOAT 33 from Germany is the world's first floated borosilicate flat glass. It combines superior quality and excellent flatness with outstanding thermal, optical, chemical and mechanical features. The chemical composition and physical properties of BOROFLOAT 33 are in accordance with DIN ISO 3585 and EN 1748 T1.
