High Demand for Crystal Grower
Thermal Technology of Santa Rosa,
Calif., has received 59 orders for its Model K1 sapphire crystal grower from customers
in Taiwan, Korea and China. In total, the growers will produce 5.2 million two-in-equivalents
per year. The Model K1, weighing 90 kg, outperforms other sapphire crystal methods,
including the HEM and Bridgman, and has a short cycle time, the company said. The
sapphire crystals are used as substrate wafers for high-brightness blue and white
LEDs, which have applications in traffic lights, backlighting for flat panel displays,
and common lighting, such as streetlights and household bulbs.
