Original Specification

‡@Granite stage is adopted in this machine; as a result, measuring precision is enhanced dramatically because of improvement of anti-versatility property.
‡AAlso, cross-roller bearing is adopted for the first time in ST series.
‡BResolution capability of motion-controller is 10 nm, and that of mechanical machine is 50 nm (ST-3020F).
‡CAOI function and etching simulator function can be built in by image treatment and data-matching with GPU technology (optional).
‡DThis machine is best suited for high precision photo-mask.


Speedy and Automatic Measuring Function by CAD data comparison
Shortening of Process Step by Automatic Preparation of Measuring Data and Measuring

Measuring treatment in screen can be done speedily. Therefore, enormous measuring points same as a few thousands and over can be measured mere a few minutes.

Convenient functionFFormat of CSV output can be customized.
CSV format is output by information for table of passing status management.


Automatic Preparation of Inspection Data
Automatic Preparation of Measuring Point from the Data
Automatic Conversion of Measuring Point by Dimension Information of DXF and DWG


In the past, a measuring program is prepared by the teaching method or manual work based on the CAD data at spend time in general. By contrast, it's possible to prepare a measuring program automatically by use of ST-F series.

Convenient FunctionFNumbering and Drawing Function of Measuring Point




Built-in Filtering Function
Subject of measuring is classified adequately by filtering function.
