- フッ素ガスを用いたプラズマエッチングによってウエーハを個々のデバイスチップに分割するウエーハの加工方法であって、
ウエーハを収容する開口部を中央に備えたフレームの該開口部にウエーハを位置付けると共にダイシングテープをウエーハの下面とフレームとに貼着してフレームユニットを形成するフレームユニット形成工程と、
ウエーハの上面に水溶性樹脂を被覆すると共にウエーハとフレームとの間に露出するダイシングテープの全面に水溶性樹脂を被覆し固化して樹脂膜を形成する樹脂膜被覆工程と、
ウエーハの分割すべき領域から該樹脂膜を除去して部分的にウエーハの上面を露出させる部分的樹脂膜除去工程と、
ウエーハの分割すべき領域にプラズマエッチングを施してウエーハを個々のチップに分割するエッチング工程と、
フレームユニットを洗浄して樹脂膜を全て除去する全部樹脂膜除去工程と、
を含み構成され、
該ウエーハと該フレームとの間に露出するダイシングテープに被覆される水溶性樹脂の樹脂膜は、該エッチング工程において施されるプラズマエッチングによっても除去されることなく残存することで該プラズマエッチングにより生成されるフッ素元素が該ダイシングテープに付着することを防止するウエーハの加工方法。 - 該フッ素ガスは、SF6、CF4、C2F6、C2F4のいずれかから選択され、ウエーハは、複数のデバイスが分割予定ラインによって区画され、上面に形成されている請求項1に記載のウエーハの加工方法。
