Glass

SVM supplies a large variety of glass wafer materials for the Semiconductor, Biotechnology, and Solar Industry.  Some of the more common glass families are below.  If you require a different material, please contact us.

Popular Glass Materials:

1. Eagle XG: This glass material is created without many of the harmful chemicals traditionally found in electronic/computer components. High chemical resistance, low density, and pristine clarity are all distinguishing characteristics of this material.

Key Elements of Eagle XG:

• Low density
• Excellent clarity
• High chemical resistance

2. Borofloat: One of the most popular brands for glass wafer fabrication is floating borosilicate glass.

Key Elements of Borofloat:

• Durability when exposed to corrosive chemicals and gasses. more than most metals and other glass substrates.
• Great mechanical strength and resistance to abrasives.
• Transparency- high ultraviolet (UV) transmission
• High chemical resistance
• Excellent flatness
• Thermal expansion same as silicon

3. D 263 T: A clear borosilicate glass that has a high chemical resistance and is produced by a SCHOTT specific down-draw method. It is available in a variety of thicknesses ranging from 0.03 mm to 1.1 mm.

Key Elements of D 263 T:

• Stable against sunlight and heat
• Not permeable to humidity
• Flexibility is similar to that of plastic
• Easy to cut by laser or scribe and break method
• Excellent resistance to chemicals.

4. Fused Quartz/Fused Silica: Quartz material is exceptionally pure and has an impressively high melting point. Fused silica wafers – also known as fused quartz wafers – are often considered ideal for use in semiconductor components.

Key Elements of Quartz/Fused Silica:

• Ultraviolet transparency – Excellent optical transmission at a wide range of wavelengths, from ultraviolet to infrared. It also transmits ultraviolet rays better than other glass.
• Extreme hardness
• High chemical purity
• Excellent resistance to chemicals.
• Large operating temperature range and resilient to thermal shock due to low thermal expansion
• Excellent electrical insulation properties
• Low refractive index.

5. Borosilicate: Widely known as one of the most affordable glass fabrication materials, borosilicate glass. A variety of borosilicate brands are available.

Key Elements of Borosilicate:

• Borosilicate glass exhibits a higher chemical stability against water, many chemicals and pharmaceutical products
• Very resilient to high temperatures fluctuations
• Good transparency
• Excellent mechanical strength.

6. Soda Lime Glass is one of the most common types of glass wafer. It is commonly used in electronic applications, microslides and mirrors.

Key Elements of Soda Lime:

• Low cost
• Excellent at reflecting infrared and transmitting visible light
• Can be chemically strengthened to harden the surface to be scratch and break resistant.
