Negative deep ultraviolet photoresist

   
   

The present invention relates to a novel negative working deep uv photoresist that is developable in an aqueous alkaline solution, and comprises a fluorinated polymer, photoactive compound and a crosslinking agent. The photoresist composition is particularly useful for patterning with exposure wavelengths of 193 nm and 157 nm.
