Thin film measurement equipment from Signatone

Signatone manufactures analytical probing equipment, thermal chucks and resistivity film measurement systems.  Since 1968, Signatone’s 4-point probing solutions are used throughout the world for characterizing materials and thin films.

Measuring films using the 4-point probe method determines sheet resistance and thickness or resistivity of the film.  The range of measurement is determined by the current and voltmeter used.  The standard range is 1µΩ to 100MΩ but other ranges are available.

Signatone offers 2 product families for film measurements-

Pro4 manual bench top system

  • Automated calculating V/I, sheet resistance, resistivity or thickness
  • samples from 10mm to 150mm

QuadProII standalone automated system

  • Automated calculating V/I, sheet resistance, resistivity or thickness
  • samples from 10mm to 300mm
  • automated mapping of sample with up to 14,000 measured points
  • 3d, 2d, and dissected 3d colored mapping
  • Comparative mapping of samples to help dial in PVD/CVD systems
  • Temperature coefficient of resistance measurements (optional)
