|2/25/2010||Sapphire Wafer Carriers Perforated With Custom Patterns|
|A low-cost line of sapphire wafer carriers that are more durable than quartz and other materials and can be perforated with custom patterns is available from Meller Optics, Inc. of Providence, Rhode Island.
Meller Sapphire Wafer Carriers are designed for thinning semiconductor materials such as GaAs and can be perforated with custom patterns for vacuum hold-down or delamination. Featuring Moh 9 hardness, sapphire offers superior mechanical strength due to its off-axis crystal growth which permits the custom fabrication of wafer carriers as thin as 0.018”.
Available in sizes from 2” to 6” dia., with flats and laser markings, Meller Sapphire Wafer Carriers are chip-, chemical-, scratch-resistant, and can withstand repeated use. Considerably stronger than quartz and other materials, sapphire is second only to diamond in terms of hardness.
Meller Sapphire Wafer Carriers are priced 30% less expensive than con-ventional perforated carries, claims the firm. Delivery is 4 to 6 weeks typical. Pricing and literature are available upon request.
