The Zygo Verifire Mask Metrology is a metrology and inspection system.[2]
A mask metrology system measures mask features and checks pattern fidelity rather than processing wafers.
A metrology and inspection tool in this class supports dimensional verification, defect review, and process control for photomask workflows.
A mask metrology tool supports inspection after mask fabrication steps and before downstream lithography use.
A system in this class is used for quality control of reticles and other mask-based lithography assets.
