평평한 기판의 Blue Wafer Epi의 경우, 우리가 llo 및 뒷면 콘센트를 원할 때 U-gan 층을 생략 / 제거하는 것이 중요합니다. 그게 가능합니까?
Q : 평평한 기판의 Blue Wafer EPI의 경우 LLO 및 뒷면 콘센트를 원할 때 U-GAN 층을 생략 / 제거하는 것이 중요합니다. 그게 가능합니까?
A : 그렇습니다. 문제가 아닙니다. 일부 고객은 LLO를 위해 웨이퍼를 구입했습니다.

For 4” pss wafer, the light comes out from the p-GaN side not from sapphire, so I can’t do flip chip packaging. Also I don’t know whether laser liftoff is possible for pss wafer. Is it possible you can share any image of the etched surface of pss?
