Abstract:
An evaluating method of a hydrophobic process state of a hydrophobic process section in a resist pattern forming apparatus having said hydrophobic process section for supplying a hydrophobic process gas to a surface of a substrate to provide a hydrophobic process to the corresponding surface thereof, a coating process section for coating the surface of said substrate with a resist, and a developing process section for supplying a developing solution to the surface of the substrate subjected to exposure to light, said method comprising the steps of:analyzing a quantity of an ionic species in a sample hydrophobic process gas of a known concentration previously; transferring the substrate subjected to the hydrophobic process by said hydrophobic process section to an analyzing section; detecting quantity of the ionic species of the hydrophobic process gas on the surface of the substrate subjected to the hydrophobic process at said analyzing section; evaluating the hydrophobic process state by comparing the analyzed result with the detected result; and adjusting a process condition of the hydrophobic process based on the result of the evaluation.
