Our production and R&D of polished sapphire substrates are mainly focused on helping our customers to achieve competitive advantages on the LED market. Our sapphire substrates contribute to improved customers’ yields, increased LED brightness and narrowed wavelength distribution.
For this reason, we develop new technologies and improve our wafers by reducing internal stress of grown crystals, enhancing wafer geometry and creating exclusive cleaning technologies, which satisfy customers’ current needs and market trends. This is why one of our recent achievements was the launch of our Ultra Clean wafers designated for microLED and PSS with an increased yield.
An indispensable component in mass LED production
A majority of LEDs are grown on sapphire substrates. Monocrystal was the first company to introduce 6-, 8- and 10-inch sapphire wafers to the market, in anticipation of the industry trends. Now the company holds a leading position on 6- and 8-inch wafer market. The key LED parameters depend on the surface quality of a sapphire substrate.
