Sapphire substrates for LEDs
Higher PSS and epi yield rate on Monocrystal wafers
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.
