2inch Patterned Sapphire Substrates,LED Chip,Substrate Material
Patterned Sapphire Substrates (PSS) are fabricated and used in GaN-based LEDs in order to increase the internal quantum efficiency by reducing GaN crystal defects. They also can improve external quantum efficiency by increasing the reflection area.
R-plane sapphire substrates are preferred for hetero-epitaxial deposition of silicon. It is used in the manufacturing of semiconductor, microwave, and microelectronic IC applications.
