Abstract
A method and a structure for reworking an antireflective coating (ARC) layer over a semiconductor substrate. The method includes providing a substrate having a material layer, forming a planarization layer on the material layer, forming an organic solvent soluble layer on the planarization layer, forming an ARC layer on the organic solvent soluble layer, forming a pattern in the ARC layer, and removing the organic solvent soluble layer and the ARC layer with an organic solvent while leaving the planarization layer unremoved. The structure includes a substrate having a material layer, a planarization layer on the material layer, an organic solvent soluble layer on the planarization layer, and an ARC layer on the organic solvent soluble layer.
