PAM-XIAMEN offers PSS patterned sapphire substrate for high brightness GaN based LED EPI growing application. The patterned sapphire substrate wafer is to grow a dry etching mask on the sapphire substrate. The mask is engraved by a standard photolithography process. Then, the sapphire is etched by ICP etching [...]
