Borofloat 33 Applications
SCHOTT's Borofloat glass is used in a variety of applications, and the advantages are impressive. For example, it has excellent optical and thermal qualities, as well as high chemical resistance. In addition, it can withstand extreme temperatures, making it ideal for use in armored glass or other demanding environments. BOROFLOAT(r) 33 is also suitable for analytical and biomedical applications.
The surface of Borofloat glass is highly resistant to water, and it is easily recyclable. Moreover, the boron trioxide content makes the glass highly chemically resistant. This means it can withstand acid and alkali attacks without breaking down. It also has a very low thermal expansion coefficient, close to silicon, which makes it ideal for window optics and oven windows.
Borofloat glass is commonly used as an inexpensive alternative to Corning Pyrex(r) glass. It is also suitable for biomedical applications, because it is non-toxic to humans. It is also useful for research on microfluidic devices. Borofloat(r) is widely used in additive manufacturing processes, and it has been used in space exploration.
The glass is extremely durable, and it can withstand temperatures of up to 450 degC. It is also resistant to abrasions and organic compounds. Borofloat(r) 33 can withstand the harshest temperatures for a long period of time, making it a great material for use in the chemical industry. It is also an excellent choice for window optics and lighting technology.
SCHOTT's proprietary microfloat production process yields a very flat surface and a homogeneous material. This combination of high flatness and high optical quality is achieved by using a special coating. This coating is composed of low emissivity silver film, which results in high broadband reflectivity in the IR and near IR. The coated surface is fully encapsulated by a multi-layer dielectric stack.

Borofloat 33 For Semiconductors
Borosilicate glass wafers are extremely thin, often used for substrate bonding in semiconductor fabrication. Borosilicate glass wafers are frequently used in the Semiconductor and MEMS industries for a wide range of applications. In the MEMS applications, the glass wafer is usually used as the substrate support during fabrication process for the thin wafers made from Silicon.
Glass wafer fabrication is a very complex process requiring special fabrication machinery and procedures. While the Swift Glass Glass Wafer Fabrication & Substratum Service is most often used for the creation of glass wafers and Silica Wafers for the MeMs & Semiconductors Industry, our completely custom processes and designs are capable of producing wafers for a variety of industries and applications. When you bring your glass wafer manufacturing projects to Swift Glass, you will have access to top-quality materials, the most advanced cutting tools and finishing machines, and one of the industrys most experienced teams.
Using the latest innovations in glass production technologies, Swift Glass is capable of fabricating a wide variety of standard or custom-designed, high-quality glass wafers that meet many applications needs. SCHOTT Advanced Optics is the only provider worldwide that offers one material family for ultra-thin glass wafers, offering a variety of performance characteristics and customized features. SCHOTT is an international technology group with over 125 years experience in the areas of special glass and materials as well as advanced technologies.
Borosilicate glass has a wide range of uses, ranging from cooking vessels to laboratory equipment, as well as being part of high-end products like implantable medical devices and devices used in space exploration. High-grade flat glass made of borosilicate is used in a wide range of industries, mostly in technological applications requiring good thermal tolerance, great chemical resistance, or a high transmission rate in conjunction with an unblemished surface finish. Ordinary, lower-cost borosilicate glass, such as is used in making cookware or even reflecting telescope mirrors, cannot be used for high-quality lenses due to striations and inclusions that are characteristic of lower grades of common, lower-cost borosilicate glass.
Boronsilicate glass wafers are perfect for micro-optical and MEMS applications. Borosilicate glass has an application also in semiconductor manufacturing for the development of Microelectromechanical Systems (MEMS) as a component in stacked layers of etched silicon wafers that are joined with the etched borosilicate glass.
B-orosilicate glasses are designed for high thermal shock resistance and temperature tolerance. The superior strength, chemical, and thermal tolerances of B orosilicate glass have found applications in laboratory equipment for chemicals, in cooking vessels, for illumination, and for some types of windows. Its thermal coefficient of expansion is similar to that of silicon, so is a good choice for wafer-level optical packaging materials in semiconductor-related applications.
It is also used as a substrate glass for coatings, or a plastic substitute, for applications in the automobile and electronics industries. Borosilicate glass is very resistant to thermal shocks, and is used for a variety of applications including high-intensity discharge lamps and organic light-emitting diodes (OLEDs). It is used extensively in practically all current lab glassware because of its chemical and thermal tolerances, as well as good optical clarity, but glass may react with sodium hydride when heated, producing sodium borohydride, a common lab reduction agent.
Precision parts can be manufactured with B-orosilicate glass, so it is specified in LCD displays, telescope mirrors, electronics sensors, and has numerous uses in optics, micro-electronics, nuclear power, and other precision engineering applications. Boresilicate glass wafers can tolerate high temperatures, and are coated with indium-tin oxide to make them transparent in the visible spectrum, and to reflect infrared spectrum back at a light source. Glass wafers may be used as a permanent support that remains on a final product, or a temporary support for smaller or thinner materials.
The following specifications of glass wafers are used to be bonding with a silicon wafer The silicon wafer, the grain size is required to comply with the SEMI standards. For cutting, designers who need precision glass parts in larger sizes often will specify Corning 7740 as their material.
We are planning on using 4-inch-wide wafers (Si, 500 microns thick) with a glass substrate thinner than 170 microns, making it possible to perform microscopy via Si-Glass devices. I have to glue together two glass wafers for my PhD, one on which there will be SiO2 layer with etchings or features some couple of hundreds of nanometers deep using Liftoff. I am looking at silicon and glass borofloat 33 wafers.A It is likely a 100mm size.A Wondering if you have some thoughts about spec on the various sandings and whatnot.A TheA applicationA is for microfluidic devices with porous media.
A Since quality/specs on the Silicon and Glass are crucial to achieving a successful anodic bond, I believe the BF33 wafers are a good choice for us to begin our work. The three different types of glass wafers produced by AF32(r) Eco, D 263T(r) Eco, and MEMpax(r) are complimentary for various semiconductor wafers, so they are suitable for a variety of applications in semiconductor manufacturing. Similar to Schotts Borofloat(r) 33 in terms of its physical, thermal and chemical properties, MEMpax(r) is targeted at applications with ultra-thin borosilicate glass, while Borofloat(r) 33 is offered at thicknesses as low as 0.7mm.
