Sapphire

A-Plane sapphire substrates are useful for hybrid microelectronic applications requiring a uniform dielectric constant and highly insulating characteristics. This orientation can also be used for the growth of high Tc superconductors.

Sapphire (Al₂O₃) boasts superior optical, mechanical and chemical properties to other common optical glasses and crystals.

Basal Plane Sapphire Substrates with one or both surfaces polished are useful for the growth of lll-V and ll-Vl compoounds, such as GaN, for bright blue and green LED and laser diodes.

Sapphire's range of superior qualities make it ideal for optical and non-optical components.
From the forward-facing optics of imaging systems to the thermal insulators in plasma systems.

Sapphire's hardness and exceptional chemical stability make it superior to other glass and crystal materials for the protection of sensors and imaging systems that are used in challenging and harsh environments.

Whilst we supply fully fabricated sapphire wafers to exacting high specifications, we also recognise the semi-finished and ingot markets. For these markets we present ingots in three most popular diameters.

By offering Sapphire grown by Stepanov, Czochralski, Kryopolus and HDSM methods, Roditi ensure that the specification is met with the best production time and cost in mind.

R-plane sapphire substrates are preferred for the hetero-epitaxial deposition of silicon used in microelectronic IC applications.

Roditi is a key supplier of sapphire substrates for photoelectronic applications, including the high brightness LED market.

With their superior technical and chemical properties, sapphire windows can be found in applications across the whole optical sector as well as in the field of measurement and analytical instrumentation.

In addition to our standard Sapphire material and components, Roditi's capabilities extend to specialist Sapphire pieces.
