Typical Single Wafer Carrier

Sapphire Semiconductor Substrates are available in all Orientations

Orientations include

Sapphire substrates are available in various shapes (circular, rectangle, or square), from a few mm up to 200mm in size, and finishes according to customer specification. Primary flats(as per industry standards) are provided on circular substrates for orientation purposes; secondary flats are available on request. Substrate thickness' range from 0.013" (0.25mm) to 0.025" (0.675mm), depending on your particular application requirements.

We have wafers in stock!

Sapphire Ingot Grow Methods

We grow are sapphire wafers using several methods

  • Czochralski (CZ) - process is known to be more efficient for c-axis sapphire substrate production.
  • Heat Exchanger Method (HEM) - Used to grow sapphire crystal in volume.
  • Kyropoulos (KY) - grows high quality sapphire but requires an enormous amount of electricity.
  • Edge defined, Film-fed (EFG) - FG technique. A crystal growth process to manufacture more than 10 crystals at one time up to 1.5mm  thick per crystal using multi-tip EFG

Below is an example of pricing for the different growth methods.

Sapphire Wafer Products

Sapphire semiconductor substrates are manufactured at Sapphire Products from high quality optical grade Czochralski sapphire. Our integrated facilities allow regulation of the production of substrates from crystal growth to fabrication, and to accommodate special requests on very short notice.

GaN on Sapphire SECTION BLUE LED SUBSTRATES

Sapphire Products is a leading provider of high quality sapphire substrates to the expanding Gallium Nitride LED based market. Substrate tolerances and surface finish are keys to Gallium Nitride device production and yield. Sapphire Products sets the standards for flatness and surface finish.

Our strong product development team uses industry standard measurement techniques, such as Atomic Force Microscopy (AFM), X-ray rocking curves and surface analysis to study surface and crystalline quality of substrates. C-axis [0001] wafers precisely oriented to within ± 0.25° and primary flat tolerances to ± 0.5° are available in 2" diameter. Other sapphire orientations, misoriented substrates, and wafer tolerances are available.

Sapphire Wafers for Dropcasting Materials

A scientists asked the following:

" I am looking for a sapphire substrate for optical characterization (high transmission) by dropcasting materials onto a wafer. The 10 x 10 mm wafer is slightly too small for my application. Is there any possibility of obtaining several 0.5 x 0.5 in (or 12.5 x 12.5 mm) wafers for this application?"

Maximum transmission across 0.2 – 5 um. Other specs as listed for the 10 x 10 mm should be fine. For quantity, what would be the cost for 5, 10, and 20 respectively?
