Description
先ず、一実施形態にかかるプラズマ処理システムについて説明する。図1は、プラズマ処理システム1の構成の概略を示す説明図である。プラズマ処理システム1では、基板としてのウェハWに対して、ALEプロセスを行う。
次に、上述したガス供給部20について説明する。図2は、ガス供給部20の構成の概略を示す説明図である。
次に、以上のように構成されたプラズマ処理システムを用いて行われるALEプロセスについて説明する。
ガス供給部20からプラズマ処理チャンバ10の内部に、処理ガスとして例えばCl2(塩素)ガスを供給し、ウェハW(シリコン)の表面に吸着させ、SiCl化合物に改質させる。
ガス供給部20からプラズマ処理チャンバ10の内部に、処理ガスとして例えばAr(アルゴン)ガスを供給し、当該Arイオンを生成する。そして、Arイオンによって、ウェハWの表面のSiCl化合物だけを選択的にエッチングする。
上述したようにALEプロセスでは、化学修飾工程とエッチング工程を行うため、処理ガスの切り替えを繰り返し、処理ガスのON/OFFが短時間で行われる。このように短時間で処理ガスのON/OFFを行うALEプロセスでは、プロセス中にリアルタイムで精度よくガス流量を監視することが必要となる。
F=P1×Fs(t)/Ps(t) ・・・(1)
F:規格化されたガスの流量(sccm)、P1:流量制御器22の1次圧力(psi)、t:ガス供給開始からの経過時間(min)、Fs(t):時間tにおけるガス流量の設定値(sccm)、Ps(t):時間tにおける流量制御器22の1次圧力(psi)
工程S1では、ALEプロセスを行う前に、当該ALEプロセスのレシピを設定する。具体的には、ガス供給開始からの経過時間tにおける、ガス流量の設定値Fs(t)とガス圧力の設定値Ps(t)とを設定する。
工程S1での事前設定が終了すると、プラズマ処理チャンバ10の内部に載置されたウェハWに対して、ALEプロセスを開始する。すなわち、工程S2では、ガス供給部20からプラズマ処理チャンバ10の内部に、処理ガスの供給を開始する。
工程S3では、処理ガスの供給中において、流量制御器22によって処理ガスの1次圧力P1を測定する。
工程S4では、下記式(1)を用いて、流量制御器22で測定された処理ガスの1次圧力P1をガス流量に換算して、規格化する。
F=P1×Fs(t)/Ps(t) ・・・(1)
F:規格化されたガス流量(sccm)、P1:流量制御器22の1次圧力(psi)、t:ガス供給開始からの経過時間(min)、Fs(t):時間tにおけるガス流量の設定値(sccm)、Ps(t):時間tにおける流量制御器22の1次圧力(psi)
ウェハWに対するALEプロセスが終了すると、工程S5では、ガス供給部20からプラズマ処理チャンバ10の内部への処理ガスの供給を停止する。
工程S6では、工程S3で測定された処理ガスの1次圧力P1が、工程S1で設定された閾値Pt以上になる時間Tを算出する。具体的には、図5に示したように前方時間Taと後方時間Tbを含む時間Tを算出する。そして、この時間Tでは、ガスON時のみの圧力の波形を抜粋してトリミングすることができる。
工程S7では、工程S4で規格化されたガス流量Fを、工程S6で算出された時間Tで積分して、処理ガスの総流量を算出する。この処理ガスの総流量は、1回のガスON/OFFにおいて、ガス供給部20からプラズマ処理チャンバ10に供給された処理ガスの総流量である。
工程S8では、工程S7で算出された処理ガスの総流量が、所望の範囲であるか否かを判定する。所望の範囲は、ALEプロセスのレシピに応じて、ALEプロセスを行う前に、予め設定しておく。例えば工程S1において、装置の立ち上げ時などに流量制御器22のガス流量のデータと実際のガス流量のデータを取得しておいて、設定してもよい。また、例えばガスON/OFFを繰り返し行い、これらのガス流量の平均値を算出してもよい。
工程S9では、工程S8において処理ガスの総流量が所望の範囲内であると判定された場合、ALEプロセスを続行する。
工程S10では、工程S8において処理ガスの総流量が所望の範囲外であると判定された場合、流量制御器22におけるガス流量の設定値Fs(t)をフィードバック制御して調整する。
