A-plane±0.2o Patterned Sapphire Substrates BOW ≤-8~0μm Edge Round
The formation of LEDs on patterned sapphire substrates is the most cost-effective method for manufacturing such devices. These LEDs exhibit high-normalized electroluminescence intensity and high light extraction efficiency.
In addition, patterned wafers reduce defect density and total internal reflection losses. These advantages are driving the adoption of nitride-semiconductor-based LEDs by manufacturers.
