If the resist is still present without an image - my guess would be that
120C for 10 minutes is to long, exposure is to short or developer may be
bad....

 I spin S1813 at 4000rpm 45s.
Then hot bake 120Degree 10min
Exposure 10s, then develop 30s.After 30s, I can't see anything.
Why???
All paper recommend the develop time 30s.
