Materials

The following glass types are available to produce the Glass Wafer & Substrates according to your requests:

  • BOROFLOAT® 33 borosilicate glass
  • Fused Silica
  • D 263 T® eco borosilicate glass
  • AF 32® eco aluminoborosilicate glass
  • B 270® low-iron crown glass


Main characteristics of BOROFLOAT® 33 borosilicate glass:

  • Low coefficient of thermal expansion -- close to silicon (a20°C – 300°C = 3.25 x 10–6 K–1)
  • Excellent transparency
  • High thermal resistance
  • High resistance to chemical solvents
  • Available in various thickness: 0.7 mm; 1.1 to 7.5 mm
  • Suitable for anodic bonding
