Sapphire wafer carriers debut from Meller Optics

February 24, 2011 — Custom fabricated sapphire wafer carriers that are uniform, parallel, and impervious to solvents and etchants for thinning semiconductor materials are available from Meller Optics Inc.

Meller Sapphire Wafer Carriers feature ±1.2µm thickness and part-to-part uniformity, with parallelism to 10arc-sec., depending upon size, and exhibit Moh 9 hardness, second only to diamond. They are suited to thinning semiconductor materials such as GaAs, available plain or 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" diameter sizes as thin as 0.018", they can be supplied with flats, laser markings, and other special characteristics.
