Abstract
【解決手段】 本発明の基板構造体を除去する方法は、基板上にフォトリソグラフィーエッチング方式で複数の柱状体を製作し、前記複数の柱状体上にIII族窒化物半導体層を成長させ、化学エッチング方式で複数の柱状体をエッチングし、前記III族窒化物半導体層と前記基板を分離する。
【選択図】 図3
Description
1、 本発明は複数の柱状体間の空隙を利用してエッチング反応面積を大幅に増加できるため、本発明が提示する方法は半導体層と基板をエッチングで分離する効率を高め、かつプロセスにかかる費用を抑えることができる。
2、 基板の分離速度が速く、かつ均一性が高く、後続の研磨プロセス(CMP)またはオーバーエッチング(Over Etching)プロセスが必要ない。
3、 高価なレーザー分離設備が必要なく、かつ基板を回収して再利用でき、コストを節約できる。
4、 本発明のエッチングは容易であり、高温が必要なく、III族窒化物半導体層に対する傷害を減少できる。室温下での一般の酸エッチング速度は約30nm/minであることに注意が必要である。厚さが約430umの基板の場合、先行技術では数日エッチングしてやっとエッチングが完了する。温度を高くしてエッチング率を高めることは、III族窒化物半導体層に傷害を与えるため、採用できない。
