Abstract: 종래의 GaN 웨이퍼는 표면이 경면 및 이면이 조면으로, 면조도의 차이를 육안으로 보아 표면과 이면을 구별하고 있었다.  그것은 알기 쉬운 차이가 아니라, 이면이 거칠어져 있으면 미립자가 부착될 우려가 있고 휨도 커져 균열 발생 및 깨짐 발생 등의 우려도 있다.  면조도의 차이를 이용하지 않고 질화물 반도체 직사각형 기판의 표리를 구별할 수 있도록 하는 것이다. 
     표리를 구별하기 위해 시계 방향으로 길고 짧은 순으로 배열하는 절결을 직사각형 GaN 기판의 2개의 모서리부에 마련하여, 하나의 모서리부에 각도가 5°내지 40°를 이루는 하나의 절결을 마련하거나, 혹은 표면측과 이면측의 모따기량을 다르게 하거나, 또는 문자를 기록하여 표리를 구별한다.  이면을 보다 평활하게 할 수 있어 표면과 상태가 근사하므로 미립자 부착이 줄어들고 휨도 감소하여, 깨짐과 이지러짐 등의 발생도 적어졌다.
