Abstract: A single layer process is utilized to reduce swing effect interference and reflection during imaging of a photoresist. An anti-reflective additive is added to a photoresist, wherein the anti-reflective additive has a dye portion and a reactive portion. Upon dispensing the reactive portion will react with underlying structures to form an anti-reflective coating between the underlying structure and a remainder of the photoresist. During imaging, the anti-reflective coating will either absorb the energy, preventing it from being reflected, or else modify the optical path of reflection, thereby helping to reduce interference caused by the reflected energy.
