Systems and methods are described for environmental exchange control for a polymer on a wafer surface. An apparatus for controlling an exchange between an environment and a polymer on a surface of a wafer located in the environment includes: a chamber adapted to hold the wafer, define the environment, and maintain the polymer in an adjacent relationship with the environment; and a heater coupled to the chamber. A method for improving performance of a spin-on material includes: forming the spin-on material on a surface of a wafer; then locating the spin-on material in an environment so that said environment is adjacent said spin-on material; and then controlling an exchange between the spin-on material and said environment. The systems and methods provide advantages because inappropriate deprotection is mitigated by careful control of the environmental temperature and environmental species partial pressures (e.g. relative humidity).
