Non-lithographic shrink techniques for improving line edge roughness and using imperfect (but simpler) BARCs

The present invention relates generally to photolithographic systems and methods, and more particularly to systems and methodologies that facilitate the reduction of line-edge roughness (LER) and/or standing wave expression during pattern line formation in an integrated circuit. Systems and methods are disclosed for retaining a target critical dimension (CD) of photoresist lines, comprising a non-lithographic shrink component that facilitates mitigating LER and/or standing wave expression, wherein the shrink component is employed to heat a particular resist to the glass transition temperature of the resist to effectuate mitigation of LER and/or standing wave expression. Additionally, by heating the resist to its glass transition temperature, the systems and methods of the present invention effectively impede deviation from a desired target critical dimension.
