Manufacture sapphires and sapphire wafers for production of LEDs and compounds for photovoltaics

Under the project, Monocrystal is producing three products in high demand in global markets:

  • Sapphire cylinders: single-crystal sapphires in cylindrical form for production of sapphire wafers
  • Sapphire wafers: the base on which to grow layers of gallium nitride, silicon, and other materials for use in opto- and microelectronics
  • Aluminum, silver, and aluminum-silver pastes: essential components for metalizing silicon solar elements

Thanks to special properties in its crystalline lattice, moderate manufacturing costs, and amenability to production in needed quantities, synthetic sapphire has become the material of choice for preparing wafers to manufacture ultrabright LEDs, microwave ICs, and optical devices.

Sapphire wafers are, as well, the feedstock for producing nanoheterostructures of gallium nitride, aluminum, and indium. Wafers four inches in diameter are used broadly to manufacture light-emitting and laser diodes in the blue, green, and ultraviolet spectrums. Blue LEDs are the basis of solid-state sources of fifth-generation (white) LEDs. In microwave engineering, nanostructures of gallium nitride and aluminum are deposited onto wafers as large as six inches in diameter. Monocrystal currently holds worldwide market shares of 25 percent in synthetic sapphires and 15 percent in aluminum compounds for solar modules.
