4 Inch SSP/DSP Dia100mm A-Plane Axis-C Sapphire Wafer Substrates
Carrier Single Crystal
Product Description:
Sapphire is a material of a unique combination of physical,
chemical and optical properties, which make it resistant to high
temperature, thermal shock, water and sand erosion, and scratching.
It is a superior window material for many IR applications from 3µm
to 5µm. C-plane sapphire substrates are widely used to grow III-V
and II-VI compounds such as GaN for blue LED and laser diodes,
while R-plane sapphire substrates are used for the hetero-epitaxial
deposition of silicon for microelectronic IC applications.
Features:
- Sapphire Wafer sizes from 2” to 150mm, from inventory
- Very high quality low defectivity and tight TTV and flatness
- High purity 99.998%
- Single and double sided polished available
- C, A, and R plane orientations
- Small lot sizes and Laser marking of wafers available
- Short lead-time for delivery
