Abstract:
Embodiments described herein generally relate to methods for mitigating patterning defects. More specifically, embodiments described herein relate to utilizing field guided post exposure bake processes to mitigate microbridge photoresist defects. An electric field may be applied to a substrate being processed during a post exposure bake process. Photoacid generated as a result of the exposure may be moved along a direction defined by the electric field. The movement of the photoacid may contact microbridge defects and facilitate the removal of the microbridge defects from the surface of a substrate.
