Use of non-lithographic shrink techniques for fabrication/making of imprints masks

摘要

The present invention relates generally to photolithographic systems and methods, and more particularly to systems and methodologies that facilitate improved critical dimension (CD) control and the reduction of line-edge roughness (LER) during pattern line formation in an imprint mask. One aspect of the invention provides for forming features having CDs that are larger than ultimately desired in a mask resist. Upon application of a non-lithographic shrink technique, LER is mitigated and CD is reduced to within a desired target tolerance.
