Gallium Nitride on Sapphire Wafers (GaN)

We grow are sapphire wafers using several methods

• Czrochroski (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

Sapphire grown using the CZ, HEM or KY methods is used for increasing and expand the production, capacity. EFG are usually used for small volume production.

Sapphire Semiconductor Substrates are available in all Orientations

Orientations include: R-axis; A-axis; C-axis;M-axis.

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.
