Abstract
Description
図1は、実施形態にかかる薬液塗布装置1の構成の一例を示す図である。図1に示すように、薬液塗布装置1は、薬液供給部10、希釈液供給部20、粘度調整部30、混合液供給部40、処理部50、及び制御部70を備える。これらの構成により、薬液塗布装置1は、基板としてのウェハW上に薬液を塗布して塗布膜を形成する。
次に、図2を用いて粘度調整ボトル300の構成例について説明する。図2は、実施形態にかかる粘度調整ボトル300の構成の一例を示す図である。図2(a)は、粘度調整ボトル300の縦方向の断面図であり、図2(b)は、粘度調整ボトル300の上面図である。図2(c)は、粘度調整ボトル300が備える多孔質ボディ310の横方向の断面図である。
次に、図3を用いて、実施形態の薬液塗布装置1における薬液塗布の処理例について説明する。図3は、実施形態にかかる薬液塗布装置1による薬液塗布処理の手順の一例を示すフロー図である。
薬液塗布装置による処理においては、ウェハ上に所望の膜厚の塗布膜を形成するため、粘度が調整された薬液が用いられることがある。しかしながら、塗布膜の膜厚を変更する際には、異なる薬液が収容されたボトルを薬液処理装置に装着し直さなければならない。また、膜厚の異なる複数種類の塗布膜を形成する際には、それぞれの塗布膜に対応する複数種類の薬液ごとに、薬液塗布装置にボトルを装着しなければならず、薬液塗布装置が大型化し高価格化してしまう場合がある。
