Description
図1は、本実施形態の洗浄用水素水の製造装置1を概略的に示す図である。洗浄用水素水の製造装置1は、半導体デバイス、液晶デバイス等の電子工業製品の製造工程で半導体基板等の洗浄に使用される、水素水にアンモニア水の添加された洗浄用水素水を製造する装置である。洗浄用水素水の製造装置1は、水素水生成部100と、アンモニア水添加部200とを備えている。
(実施例1)
図1に示すのと同様の装置を用いて、洗浄用の水素水を製造した製造された洗浄用の水素水は、枚葉式の洗浄装置において、半導体ウエハの洗浄に用いた。
実施例で用いた装置において、超純水供給管25を、計量タンク12に代えて、希釈タンク13の下部に接続して、希釈用の超純水を希釈タンク13内に供給した。計量タンク12の洗浄を行わない以外は実施例と同様の操作を行い、洗浄後のウエハ表面の微粒子数の測定を行った。測定した微粒子数を、洗浄開始直後のウエハ表面の微粒子数を1とした相対値で表1に示す。
比較例において約4か月後に、実施例1と同様にして計量タンク12の洗浄を行ったところ、ウエハ表面上に発生した微粒子数は洗浄初期と同等の数まで減少した。このことから、ウエハ表面の微粒子が、計量タンク12内に残留するアンモニア由来のものであると考えられる。
