|2/23/2011||Sapphire Wafer Carriers are Uniform, Parallel and Durable|
|Custom fabricated sapphire wafer carriers that are uniform, parallel, and impervious to solvents and etchants for thinning semiconductor materials
is available from Meller Optics, Inc. of Providence, Rhode Island.
Meller Sapphire Wafer Carriers feature ±1.2 µm thickness and part-to-part uniformity, with parallelism to 10 arc-sec., depending upon size, and exhibit Moh 9 hardness which is second only to diamond. Ideally suited for thinning semiconductor materials such as GaAs, they are available plain and can be perforated with custom patterns for hold-down or delamination.
Impervious to solvents, etchants, and capable of withstanding repeated use, Meller Sapphire Wafer Carriers are chip-, chemical-, and scratch-resistant. Custom fabricated in 2” to 6” dia. sizes as thin as 0.018”, they can be supplied with flats, laser markings, and other special characteristics.
Meller Sapphire Wafer Carriers are priced according to size and configur-ation with typical 4-6 week delivery. Pricing and literature are available upon request.
