Product Description
MDXN-25D4 High precision mask aligner
Purpose and characteristics:
This equipment is mainly used for the development and production of small and medium-sized integrated circuits, semiconductor components, and surface acoustic wave devices. Due to the advanced leveling mechanism and low leveling force, this machine is not only suitable for the exposure of various types of substrates, but also for the exposure of easily fragmented substrates such as potassium arsenide and phosphate steel, as well as the exposure of non circular and small substrates.
