Zusammenfassung:	A method for patterning a photo-resist in an immersion lithography process is described. The method includes forming a photo-resist layer above a substrate. A hydrophobic and contrast-enhancing barrier layer is formed above the photo-resist layer. The photo-resist layer is exposed, through the hydrophobic and contrast-enhancing barrier layer, to a light source. The photo-resist layer is developed to provide a patterned photo-resist layer.
