Synthetic sapphire is transparent single crystal 99.99% pure Al2O3 that exhibits a unique combination of physical, chemical,
electrical and optical properties: high thermal conductivity, high
strength and scratch resistance, hardness (9 on the Mohs scale),
transparent in wide range of wavelength, chemical inertness.
High crystal perfection, low reactivity, and appropriate unit cell
size make sapphire an excellent substrate in the semiconductor
industry for blue light-emitting diodes (LED).
Since Nobel Laureate in Physics Shuji Nakamura used the sapphire
substrate in 1990s for LED, the demand of sapphire crystal has been
growing rapidly. It drives development of new markets like general lighting,
backside lighting in TV-sets, displays, consumer appliances,
aerospace and defense, and other applications The material is grown and orientated, and substrates are fabricated
and polished to an extremely smooth damage free Epi-Ready surface
on one or both sides of the wafer. A variety of wafer orientations
and sizes up to 6" diameter are available. A-Plane sapphire substrates - are usually used for hybrid microelectronic
applications requiring a uniform dielectric constant and highly
insulating characteristics. C-Plane substrates - tend to be used for lll-V and ll-Vl compounds, such
as GaN, for bright blue and green LED and laser diodes. R-Plane substrates - these are preferred for the hetero-epitaxial
deposition of silicon used in microelectronic IC applications. Standard wafer 2 inch C-plane sapphire wafer SSP/DSP
