Abstract
The purpose of this article is to propose a residue-free process using ANR resists specifically designed for deep UV lithography. The influence of development steps, process conditions and resist formulation on residues were studied. An optimized process point with a new resist formulation is proposed. Using this residue-free process point, very high resolution was achieved for deep UV and e-beam lithography. Moreover, the temporal effects on the coated wafers were investigated.
