Abstract:
A method for improving photosensitivity of a material, comprising:forming a layer of photosensitive material on a surface; locating the surface in a first fluid environment within a processing chamber, wherein a first fluid is in contact with the photosensitive material; controlling an exchange of mass between the photosensitive material and the first fluid environment, wherein the exchange of mass is controlled by: measuring at least two independent thermodynamic variables of the first fluid; and introducing and extracting chemical species to the first fluid environment responsive to the measurements; exposing the photosensitive material; establishing a second fluid environment, wherein a second fluid is in contact with the photosensitive material; and controlling an exchange of mass between the photosensitive material and the second fluid environment, wherein the exchange of mass is controlled by: measuring at least three independent thermodynamic variables of the second fluid; and introducing and extracting chemical species to the second fluid environment responsive to the measurements.
