substrate / sapphire

Sapphire Single Crystal Sapphire substrates are ideal for epitaxial deposition of GaN and other III-V and II-VI thin-films for use in the manufacture of bright blue and green LED's. C-axis [0001] oriented wafers are available in the sizes shown below. One side is highly polished to 1 nm or less and the second side is either fine ground or optically polished. The parts are available in lots of 10 or 25 in cassettes packaged in Class-100 clean room under nitrogen and are EPI ready.

Sapphire Substrates are custom fabricated to order and typically require a 1 week lead time.
