Borofloat 33 Glass Wafers

Borofloat 33 glass wafer is used in a wide range of applications like micro-optics, sensors, microlithography, semiconductor engineering, lighting, medical technology, etc and it has outstanding properties. It is manufactured using the latest technology and features a clear, colorless, high-quality mirror-like surface and excellent optical quality. It has a uniform thickness, low internal stresses, and is resistant to thermal shock.

WaferPro offers a wide variety of high-purity borofloat 33 glass wafers for the semiconductor industry because they are chemically inert and have low levels of density variation across the surface.

WaferPro also offers borofloat 33 glass wafers for the microelectronics industry from our exclusive plant. As a leading supplier of high-purity borofloat 33 glass wafers, we are able to meet any customer need with our extensive product lines. We deliver our high-purity borofloat on time, every time, with consistent quality.
