Abstract:
1. A wafer processor, comprising: a processing chamber; means for forming a layer of unexposed photoresist polymer on a surface of a wafer, the wafer being stationary relative to the processing chamber; means for measuring at least two independent thermodynamic variables of a first fluid, the first fluid being in contact with the unexposed photoresist polymer and defining a first fluid environment; means for introducing and extracting chemical species to the first fluid environment responsive to the measured at least two independent thermodynamic variables of the first fluid; means for measuring at least three independent thermodynamic variables of a second fluid, the second fluid being in contact with exposed photoresist polymer and defining a second fluid environment; means for introducing and extracting chemical species to the second fluid environment responsive to the measured at least three independent thermodynamic variables of the second fluid.
