Glass Wafer Processing Case Study<\/h1>\n

For glass discs and wafer substrates, we control material, diameter, thickness, edges, two-sided condition, cleaning and packaging together.<\/p>\n<\/div>\n<\/div>\n<\/article>\n<\/section>\n

Project Overview<\/span><\/div>\n

The complete route from material confirmation to finished-part delivery<\/h2>\n

Glass wafers usually serve sensing, microelectronics, optics and packaging projects. Beyond diameter and thickness, attention should go to flatness, thickness variation, edge profile, two-sided appearance, orientation marking and clean packaging, with acceptance defined together with downstream coating, bonding or lithography processes.<\/p>\n

Typical materials<\/dt>\n
Fused quartz, BOROFLOAT\u00ae 33, alkali-free glass and others<\/dd>\n<\/div>\n

Derive glass wafer specifications from the downstream process<\/h2>\n

A glass wafer is not finished by simply cutting a flat plate into a circle. Downstream lithography, bonding, coating and equipment handling each map to TTV, Bow\/Warp, edge, locating features, surface and particle requirements, all of which must be confirmed together before material is purchased.<\/p>\n<\/div>\n
