A process for fabricating a semiconductor device, including applying an
immersion lithography medium to a surface of a semiconductor wafer;
exposing a material on the surface of the semiconductor wafer to
electromagnetic radiation having a selected wavelength; and applying
supercritical carbon dioxide to the semiconductor wafer to remove the
immersion lithography medium from the surface of the semiconductor wafer.
In one embodiment, the process includes recovery of the immersion
lithography medium.
