Abstract
The present invention discloses a positive and negative dual function magnetic resist lithography method. At first, a substrate coated with a positive and negative dual function magnetic resist layer is provided. The positive and negative dual function magnetic resist layer comprises a manganese(Mn)-containing precursor and at least one hydrophilic polymer. Next, at least one exposure procedure for the positive and negative dual function magnetic resist layer is performed to form either a positive resist or a negative resist. In addition, after the at least one exposure procedure, a developing procedure using water-soluble developer is performed.
