  • Abstract
    Photolithography on the sample surface with vertical side walls is studied. In the angled exposure for patterning side walls or bottoms, the reflection of the exposing light is necessary to be minimized for obtaining the defect-free pattern. The liquid immersion method is applied. With the polarization control, the optimum pattern is obtained using the single shot exposure.
