Abstract
Description
前記洗浄対象物が置かれたプラズマ洗浄室内に酸素ガスと水素ガスとを導入し、
前記酸素ガスと水素ガスとから成る混合ガスをプラズマ化する
工程を含むことを特徴とする。
前記洗浄対象物が置かれたプラズマ洗浄室内に水蒸気を導入し、
前記水蒸気をプラズマ化する
工程を含むことを特徴とする。
酸化防止効果は、プラズマ処理後の銀表面の変色発生の有無を目視で確認する方法で調べた。その結果、図8に示すように、H2/O2ガスの場合は、銀表面の変色が発生しないのはO2の濃度(体積比)が60%までであった。水蒸気+酸素ガス(H2O/O2ガス)の場合は、O2濃度が80%まで変色が生じず、高い酸素濃度でも酸化を防止することができることが分かった。
