Paper Abstract

UVLED array aligner for proximity and soft contact exposure has been designed and fabricated. The source is designed for a lithography aligner, each UVLED is arranged in a plate with equal space to form UVLED array source. With AAAAS illumination optics, the aligner is built and has provided the uniformly source. 12 inches wafer with 0.6 micron mask for TSV process has proved in soft contact and proximity exposure modes, with less 1 microns for soft contact. 20 microns for 100 microns proximity exposure, with deviation of 1 micron.
