ABSTRACT:
A pattern forming system1includes a checking apparatus400and a control section500. The checking apparatus400is configured to measure and check a sidewall angle SWA of a resist pattern formed on a substrate W after a developing process. The control section500is configured to use a difference between a target value of the sidewall angle SWA of the resist pattern after the developing process and a check result of the sidewall angle SWA obtained by the checking apparatus400, to set a process condition for a first heat process71to74or a second heat process84to89so as to cause the sidewall angle SWA to approximate the target value thereof after the developing process.
