Claim 10:
11. The plasma processing method according to claim 9, comprising:
(i) detecting a shape of the recess before (c);
(n) detecting a shape of a pattern formed by the etching and/or the state of the film on the recess after (g);
(o) obtaining correlation between the state of the film before and after (g), the state of the plasma, and the shape of the pattern after (g) based on the state of the film detected in (f), the state of the plasma monitored in (d), and the shape of the pattern and/or the state of the film on the recess detected in (n);
(p) correcting the processing condition in (g) based on the correlation; and
(q) etching a substrate different from the substrate under the processing condition corrected in (p).
