ABM 3000HR Mask Aligner


The 3000HR series Mask Aligner is high resolution, Contact/Proximity Aligner. The system offers precise and repeatable sub-micron alignment and exposure for many wafer and substrate sizes. This includes sensitive, brittle and odd shaped materials. The precision wedge-error compensation vacuum chucks offer consistent mask to substrate planarization for accurate separation adjustment and ease of alignment.
