Sapphire for LEDsSapphire for LEDs Sapphire ingots are mainly used for high brightness LED substrates (2-6 inches). LED applications: lamps of all types, backlit TVs, laptops, mobile phones, outdoor advertising and etc. LED is the key sapphire application in our days. LED substrates are the most effective sapphire application in comparison of cost and quality.


Sapphire for microelectronicsSapphire for microelectronics Sapphire substrates are the largest sapphire application. Sapphire substrates are used for semiconductor film epitaxy (GaN, Si, AlGaN and others) and for producing of integrated circuits. The sapphire substrates advantages are inertness, mechanical load and high temperature operation ability, large diameter. Therefore sapphire substrates are used even when lattice parameters don’t coincide with the heteroepitaxial structure parameters.


Sapphires for opticsSapphires for optics Sapphire is widely used for optic and optoelectronic devices such as: observation windows (with dimensions from several millimeters to several hundred millimeters) used on land, underwater and in space; lenses and prisms; all temperature LEDs; focusing cones; high-temperature protective covers for thermocouples; special lamp shells; navigation device protective caps and many others.


Sapphires for medical equipmentSapphires for medical equipment Sapphire applications in medicine: implants, surgery and medical devices. Sapphire can be implanted into the body tissues because it doesn’t react with organic acids and tissues, sapphire surpass all construction materials in inertness and biocompatibility.


Sapphires for watchesSapphires for watches Synthetic sapphire is used for watch jewels manufacturing (axial and friction bearings). It is an affordable, stable quality, solid and durable material for friction units. Watch glasses made of light-colored and wait sapphire are used by all known watch manufacturers. The matter is not just in fashion, there are no scratches on the sapphire glasses.


Techsapphire Ltd.


Products and services we can offer:

1. For Kyropoulos (SOI) method growth

1.1. Manufacturing, connecting and start-up of the furnaces for growing sapphire ingots of diameter/weight (mm/kg) 23/200, 32/200, 54/250, 65/300, 85/300. Our furnaces operated by computerized control system with special program for highly automated growth process. Crystal growth process control program takes account actual weight and weight increment of growing crystal, as well as hot zone temperature characteristics automatically (after manual seeding) in accordance with standard size. Monitoring and adjustment of the growth process can be performed directly from the equipment as well as online via the Internet.

1.2. Hot zones assembling for all standard sizes. Our hot zones are energy-efficient and long-live. Several kinds of designs and materials are used for the hot zone assembling depending on the total cost, life time and energy saving requirements.

1.3. Development and control of utilities installation for growth departments (electricity, circulating water cooling system, extraction of exhaust gases from the vacuum system, ventilation system, etc.)
1.4. Customer’s site staff training (3 up to 6 months), technology consulting support during a year. Growth processes on-line technology support.

1.5. Selection, analysis and recommendations for raw and other materials supplies.

1.6. Supplied equipment guaranty and post-guaranty repair.

Top-level SCADA system implements rendering and growth process parameters archiving of several furnaces remotely. Growth parameters adjustment, scrolling, analysis, printout, filtering, charting and reporting based on the archived data of previous processes.
