Resistivity Measurement System (manual type) VR300DEC



VR300DEC is a manual type four-probe measurement System.
Thanks to our probe movement control systems, which is one of our core technologies, the System can measure a resistance and a sheet resistance of conductive samples such as silicon wafers, magnetic thin plates, etc. with a high degree of accuracy.


  • Wafer size: 75mm (three inches) ‐ 300mm
  • Probe movement control mechanisms measure very thin films and very shallow ion implantation layers keeping high accuracy.
  • Optimum prove movement can be set up with recipes.
  • It is possible to make images such as contour maps or 3D maps to show resistance distribution.
  • A function for host communication is available.


  • Materials such as silicon, polysilicon, etc.
  • Ion implantation, diffusion, metal films, etc.
