Semiconductor Glass Fabrication | Glass Wafers

At Swift Glass, we fabricate custom glass wafers that adhere to the high standards of the semiconductor industry. Our glass wafers can be used as temporary or permanent semiconductor materials. Glass wafers used for semiconductors are thin, precision-fabricated glass discs made of fused silica, quartz, or borosilicate glass and act as carriers for Micro Electro Mechanical Systems (MEMs) substrates like silicon.

Understanding the material options and capabilities used to fabricate glass wafers will help you determine the ideal solution for your semiconductor application.

Semiconductor Glass Fabrication Solutions From Swift Glass

Swift Glass has a prototype and specialty production shop that handles small to large production runs, with a minimum production run of one unit. We can scale our operations based on your fabrication needs and use advanced systems to cut wafers of various materials with thicknesses as small as 0.3 mm. When you trust Swift Glass with your glass wafer manufacturing needs, you benefit from high-quality fabrication materials, sophisticated cutting tools, finishing machines, and our industry-leading experience.

Glass Semiconductors

Benefits of Using Glass in Semiconductor Applications

Glass, which can be customized to meet the unique needs of customers, has many benefits for semiconductor applications. Due to its transparency, glass facilitates laser debonding. Other advantages the material offers over conventional silicon wafers include lower cost, less electrical loss, thermal stability, reduced thermal expansion, and greater stiffness to reduce warping. Glass wafers can be safely handled despite their slim size and fragility. Because of these traits, glass is ideal for semiconductor manufacturing.

Glass Materials for Semiconductor Manufacturing

Swift Glass uses the following materials in our semiconductor glass fabrication projects:

  • Borosilicate: Borosilicate offers exceptional thermal stability, making it ideal for high-quality, heat-tolerant glass parts. It is composed of high concentrations of boron trioxide and silica and offers resistance to thermal shock.
    • Corning Eagle XG®: Corning’s Eagle XG® slim glass substrate has a coefficient expansion similar to silicon, making it ideal for semiconductor applications. This glass is exceptionally thin and contains no heavy metal additives, which reduces the environmental and adverse health effects of fabricating the glass.
    • Schott BOROFLOAT® Glass: Schott BOROFLOAT® Glass is a cutting-edge material that offers toughness, chemical resistance, and thermal resistance in a lightweight, transparent package. Its versatility makes it suitable for many applications, including semiconductor manufacturing.
  • Quartz/Fused Silica: Quartz is a high-purity material that withstands the pressures and high temperatures associated with manufacturing semiconductors. Fused silica is also ideal for its near-zero thermal expansion, UV transparency, and shock resistance.
