A mixture injection port is capable of suppressing the continuous accumulation of medical fluid or blood therein and allowing efficient internal cleaning. A recirculation part is formed at a step between an inner cavity and a narrow tube part. Even if the fluid is accumulated in a clearance area produced in the inner cavity when a luer is inserted into a slit, the fluid can be securely replaced with the fluid newly flowing therein through a septum and the continuous accumulation of the fluid can be suppressed. A more efficient internal cleaning can be realized by installing a fluid accumulation prevention part such as an annular rib between the septum and the inside wall of the inner cavity and burying the clearance area.

After rinsing, while rotating a substrate, a front layer part of a rinsing liquid (DIW) adhering to a substrate surface is drained and removed from the substrate surface. This is followed by supply to the substrate surface of a liquid mixture which is obtained by mixing IPA and DIW together. Since a majority of the rinsing liquid on the substrate surface is removed off from the substrate surface, even when micro patterns are formed on the substrate surface, the liquid mixture replaces the liquid component adhering to the gaps between the patterns. Further, the IPA concentration in the liquid mixture supplied to the substrate surface is set to 50% or below. Hence, it is possible to effectively prevent destruction of the patterns while suppressing the consumption amount .
