The laser-based mask defect repair systems are intended to repair photomasks with transparent and opaque defects.
A contour-projection method is used to form an optical image for the repair of opaque defects. Transparent defects are repaired through the laser-stimulated vapor deposition of metal-organic compounds.
Defects are detected automatically on the bases of the defect file formed at the inspection stage.
The model line of the laser-based mask defect repair systems, developed and manufactured by the company, is presented in the table as follows:
