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 One of the most common types of glass wafer. 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.
