Claim 12:
13. The substrate processing method according to claim 8, wherein
said substrate processing apparatus further comprises:
a third supply liquid line in which a third supply liquid continuously flows; and
a third concentration measurement part provided in said third supply liquid line,
said first processing liquid adjustment part further comprises:
a third branch line in which said third supply liquid flows, wherein the third branch line comprises a first end that is directly connected to a third connection position on said third supply liquid line, wherein a second end of the third branch line is connected to the mixing part; and
a second flow rate adjustment part provided in one of said first to third branch lines, wherein the one of said first to third branch lines is different from the branch line comprising the first flow rate adjustment part,
and wherein said first supply liquid and said second supply liquid are pure water and said third supply liquid is a liquid other than pure water,
said substrate processing method further comprising:
measuring a dissolved concentration of said gas in said third supply liquid by said third concentration measurement part,
wherein said first to third supply liquid are mixed by said mixing part, to thereby generate said first processing liquid in said operation c), and
said first flow rate adjustment part and said second flow rate adjustment part are controlled on a basis of respective measured values of said first to third concentration measurement parts so that a dissolved concentration of said gas in said first processing liquid becomes a set value in said operation d).
