Abstract
A method of process chemical temperature control for resist stripping of a substrate in a resist stripping system includes selecting at least two temperature control objectives and selecting at least two temperature control operating variables for optimization to achieve the at least two temperature control objectives. The method further includes injecting and mixing a first process chemical and a second process chemical into a treatment liquid delivery system of the resist stripping system, which forms a treatment liquid including an active species. The method further includes injecting vapor into the treatment liquid delivery system. The vapor is injected into the treatment liquid or the treatment liquid is injected into the vapor. Treatment liquid is dispensed from the dispensing device onto the substrate. At least two of the temperature control operating variables are adjusted in response to at least two metrology data values.
