Description
まず、プラズマ処理装置1の一例について、図1を参照しながら説明する。本実施形態にかかるプラズマ処理装置1は、容量結合型(Capacitively Coupled Plasma:CCP)の平行平板プラズマ処理装置である。プラズマ処理装置1は、ウェハW上をエッチングするためのプラズマを生成するプラズマ生成手段を有する。なお、プラズマ処理装置1は、処理容器10の内部に配置される部品を有し、基板を処理する基板処理システムの一例であり、前記部品は、前記部品の表面状態に応じて前記部品の原料を供給しながら前記原料にエネルギービームを照射する工程により形成される。
次に、3Dプリンタ100の構成一例について、図2を参照しながら説明する。図2は、一実施形態に係る3Dプリンタ100の構成の一例を示す。本実施形態に係る3Dプリンタ100は、処理容器10内に配置され、プラズマにより消耗する部品(消耗部品)を修復する装置の一例である。ただし、消耗部品を修復する装置は、図2に示す3Dプリンタ100の構成に限られない。
まず、3次元スキャナ200の構成の一例について、図3を参照しながら説明する。図3は、一実施形態に係る3次元スキャナ200の構成の一例を示す。本実施形態に係る3次元スキャナ200は、エッジリング87の消耗状態を測定する装置の一例であり、かかる構成に限られない。
次に、3次元スキャナ200の動作の一例について図4を参照しながら説明する。図4は、本実施形態に係る3次元データ生成処理の一例を示すフローチャートである。本処理は、プラズマ処理装置1にてプラズマ処理が所定時間行われたとき、又はプラズマ処理装置1に配置されたエッジリング87が所定以上消耗したときに開始される。エッジリング87の消耗度合いは、処理されたウェハWのエッチング形状、エッチングレート等のエッチング特性から判定してもよい。消耗したエッジリング87は、プラズマ処理装置1から取り外され、3次元スキャナ200に運ばれる(ステップS10)。
次に、3Dプリンタ100の動作の一例について、図5を参照しながら説明する。図5は、本実施形態に係る部品の修復、形成処理の一例を示すフローチャートである。本処理が開始されると、第2制御部150は、3次元スキャナ200から3次元データを受信する(ステップS20)。
なお、本実施形態では、エッジリング87の修復を行う3Dプリンタ100の一例として指向性エネルギー堆積型の3Dプリンタを適用した。指向性エネルギー堆積型の3Dプリンタでは、粉末状又はワイヤ状の原料を供給しながら、チャンバ110内の空間において原料をレーザ光で溶かし、溶かした原料を部品の所定位置に堆積させて部品の修復を行う。しかし、3Dプリンタ100は、かかる構成の3Dプリンタに限られない。
