Abstract
Description
図2では図示が省略されているが、めっき処理部5は、不活性ガスを噴出する1又は複数のガス供給口を有するガス供給部を更に備える(後述の図3〜図6の符号「11」参照)。ガス供給部は、基板保持部52により保持されている基板Wと蓋体6との間のスペースに不活性ガスを供給し、基板Wの周囲を低酸素雰囲気にする。
図3は、第1典型例に係るガス供給部11の概略構成を示す断面図である。図3において、上述の図1及び図2に示す要素と同一又は類似の要素は、同一の符号が付され、その詳細な説明を省略する。なお理解を容易にするため、図3に示す要素の形状や寸法比は、必ずしも図1及び図2に示す要素の形状や寸法比には対応していない。また図3では一部要素(例えば蓋体カバー64等)の図示が省略されている。
図4は、第2典型例に係るガス供給部11の概略構成を示す断面図である。図4において、図1〜図3に示す要素と同一又は類似の要素は、同一の符号が付され、その詳細な説明を省略する。図4に示す要素の形状や寸法比は、必ずしも図1及び図2に示す要素の形状や寸法比には対応しておらず、また図4では一部要素の図示が省略されている。
図5は、第3典型例に係るガス供給部11の概略構成を示す断面図である。図5において、上述の図1〜図4に示す要素と同一又は類似の要素は、同一の符号が付され、その詳細な説明を省略する。図5に示す要素の形状や寸法比は、必ずしも図1及び図2に示す要素の形状や寸法比には対応しておらず、また図5では一部要素の図示が省略されている。
図6は、第4典型例に係るガス供給部11の概略構成を示す平面図である。図6において、上述の図1〜図5に示す要素と同一又は類似の要素は、同一の符号が付され、その詳細な説明を省略する。図6に示す要素の形状や寸法比は、必ずしも図1及び図2に示す要素の形状や寸法比には対応しておらず、また図6では一部要素の図示が省略されている。
図7は、めっき処理方法の一例を示すフローチャートである。本典型例はめっき処理方法(すなわち基板液処理方法)に関連しており、特にガス供給口13からの不活性ガスの噴出タイミングに関する。そのため本典型例に係るめっき処理方法は、例えば上述の第1典型例〜第4典型例に係る装置によって実施されてもよいし、他の構成を有する装置によって実施されてもよい。
