Abstract

Arbitrary and reconfiguration pattern transfer photolithographic process using deep blue light source (405 nm) with off-axis phase-only beam shaping system is reported in this study. The LCoS panel uniformity error is below 1.41 % with 8 ms response time. Reconstructed diffraction images from CGH patterns were displayed on 8° off-axis screen/target plate. The linearly calibrated look-up table (LUT) showed better performance in suppressing the zero-order intensity. The ghost image was solved as well. The diffractive images generated from linear LUT can be applied in the maskless lithographic pattern. The periodic stripe pattern at 35 pm width with 2 pm thickness photoresistant film was demonstrated using the reported optical system.
