The Nikon MF 501 is a digital length measuring system.[1]
What it is
The Nikon MF 501 is a digital length measuring system.[1]
How it works
General reference — not yet source-verifiedDigital length measuring systems typically combine a precision positioning stage with an optical microscope and a measurement scale or interferometer to determine distances between features on a substrate.
The system stages the sample under the microscope, and the measurement device records the position of the stage as the microscope is focused on alignment marks or edges.
Where it fits in the process flow
General reference — not yet source-verifiedDigital length measuring systems may also be used to qualify reticles and masks before they are used in the lithography process.
Applications
General reference — not yet source-verifiedApplications include overlay metrology, critical dimension measurement, and reticle qualification.
The systems are also used for coordinate measurement of features on photomasks and wafers in advanced process control loops.
