Polished Glass Wafers and Substrates to SEMI Standards

Glass wafers and glass substrates including Fused Silica, Fused Quartz, Soda Lime Glass, BK7, 1737F, AF45, B270, D263, LASFN9, Borosilicate glass, and other materials such as 99.6% and 96% Alumina, Sapphire and Aluminum Nitride, are available to SEMI specifications in sizes ranging from 50mm (2") up to 300mm (12"). These wafers can also be fabricated with a SEMI notch or one or two SEMI flats.

The surfaces of these glass substrates and glass wafers can be opaque or polished on one or both sides with chamfered edges. Custom wafers can also be supplied to specific thicknesses with tight tolerances including "ultra-thin" - 0.001" (25 microns) thick.

Edges can be optically polished or rounded. Wafer cassette packaging available.

Typical Glass Substrate and Glass Wafer Applications:

  • Thin film glass substrates
  • Cover glass
  • Optical window windows
  • Monitor wafers
  • Dummy wafers
  • Mirror coating substrates
  • Optical coating substrates
  • Touch control panels
  • LCD
  • Solar cells
  • Electroluminescent displays
  • MEMS and SOI
