Description
複数の洗浄処理部を備えた基板処理装置が知られている(例えば特許文献1を参照)。
以下に、運転方法の第1実施形態について、図3のフローチャートおよび図4のタイムチャートも参照して説明する。運転方法の第1実施形態は、DIW供給源60Aから供給されるDIWの温度の変動への対応に関する。
- 液位L1のときにタンク32内にある薬液は60リットルである。
- タンク32内の液位をL2からL1にするのに必要な薬液は20リットルである。
- 1つの処理ユニット16が1枚のウエハWを処理するときには、流量2L/min(リットル/毎分)でウエハWに薬液を供給する。
- 通常運転時には、5つの処理ユニットが同時にウエハWに希釈薬液を供給している(但し供給開始のタイミングはずれている)。
上記のことから、比較的高頻度、例えば数分に一回の頻度で、タンク32内の液位をL2からL1にするための薬液の補充が行われること、並びに、一回の薬液の補充時には、それまでにタンク32内に存在していた薬液の総量の数10%の薬液が追加されることがわかる。なお、上記の条件は個々の処理装置の仕様、実行される処理に応じて変化するもものであり、あくまで一例に過ぎないことを理解されたい。
次に運転方法の第2実施形態について、図5のフローチャートを参照して説明する。運転方法の第2実施形態は、(複数の)処理ユニット16が要求する薬液(処理液)の供給レートを満足するように液供給部60が薬液を供給できない事態への対応に関する。このような事態は、例えば、工場用力系のDIW供給源60Aから供給しうるDIWの供給レート(流量)が一時的に減少していることが原因で生じうる。また例えば、基板処理装置で、一時的に、特定の1つまたは複数のロットのウエハWに対して、薬液を大量に消費する処理を行ったことが原因で生じ得る。
