Description
図1は、第1実施形態の半導体製造装置の構造を示す斜視図および上面図である。
符号T1は、各ウェハの搬入および搬出に要する搬送時間を表す。符号T2は、各ウェハの処理準備に要する処理準備時間を示す。処理準備の例は、チャンバ1内の真空引きなどである。符号T3は、各ウェハの実際の処理に要する処理時間を示す。符号Nは、ウェハW1〜W4の枚数(ここではN=4)を示す。
第1比較例においては、ウェハW1〜W4の搬送、処理準備、処理がN回繰り返し実行される。一方、第2比較例においては、ウェハW1〜W4の搬送はN回繰り返し実行されるものの、ウェハW1〜W4の処理準備および処理はまとめて1回だけ実行される。よって、第2比較例によれば、ウェハW1〜W4のトータル処理時間Tを短縮することができる。しかしながら、バッチ処理装置内のウェハW1〜W4の位置によりウェハW1〜W4の処理速度が異なるため、第2比較例ではウェハW1〜W4間の特性がばらつく可能性がある。
=T1N2+T2N+T3 ・・・(3)
本実施形態においては、処理期間ごとにウェハW1〜W4の位置を変更するため、各処理期間前のウェハW1〜W4の搬送時間はT1Nである。また、本実施形態においては、処理期間ごとにウェハW1〜W4の処理準備を1回行うため、各処理期間前のウェハW1〜W4の処理準備時間はT2である。また、各処理期間のウェハW1〜W4の処理時間は、上述のようにT3/Nである。よって、本実施形態のウェハW1〜W4のトータル処理時間Tは、これら搬送時間、処理準備時間、処理時間の和をN倍して、上記の式(3)のように与えられる。
式(4)を解くと、ウェハ枚数Nの条件が以下の式(5)のように与えられる。
図4は、第1実施形態の半導体製造方法の利点を説明するための断面図である。
図5は、第2実施形態の半導体製造方法を説明するための図である。本実施形態の半導体製造方法は、図1の半導体製造装置により実行される。
