Abstract
The present invention prevents cross-linking between multiple resists that are used in the fabrication of a semiconductor device. In order to prevent resists in close proximity or contact with one another from cross-linking, a non-reactive separation layer is disposed between the resists. The separation layer prevents incompatible components of the resists from reacting with one another. Forming the separation layer between the resists allows a resist located above the separation layer to be polymerized and patterned as desired without patterning another resist located below the separation layer. Methods of patterning multiple resists are also disclosed.
