Supply of Maskless Lithography Machines
Maskless lithography machine Model: DS-2000/14
1. Technical features
Uses DMD as a digital mask with a pixel of 1024 × 768
Uses a 14x reduction projection lithography objective lens for imaging, and the single exposure area is about 1mm×0.75
Uses the patented technology - building block misaligned fly-eye lens to achieve uniform illumination.
Uses imported precision gratings, imported motors, imported guide rails, and imported lead screws to achieve precise workpiece positioning and exposure stitching, and can adapt to 100×100mm substrates.
Uses a CCD focus detection system to achieve full-field leveling, automatic field-by-field focusing or automatic field selection focusing exposure.
Has an alignment function
