Back Surface Roughness 0.8~1.2μm Patterned Sapphire Substrates Round Edge
2inch Patterned Sapphire Substrates,LED Chip,Substrate Material
Patterned Sapphire Substrates (PSS) is a micro-patterned sapphire substrate. It has been widely used in high-power GaN-based Light Emitting Diodes (LEDs), which are the most promising alternative light source for general lighting. With the breakthrough of the patterned-sapphire substrate technique, the efficacy of high-brightness GaN-based LEDs has been driven to a record high of 150 lm/W.
