Jandel, FPP 5000

Equipment: Jandel, FPP 5000
Technique: Four-point-probe technique 
Responsible: Joana Pinto /

Description: A four-point-probe technique for measuring semiconductor resistivities, which is easy to implement, nondestructive, and especially convenient for probing the wafers used in device fabrication. Resistivity measurements are made on the flat ends of the crystal, were current (I) is passed through the outer probes and voltages (V) measured between the inner probes.

Specifications: 

  • Maximum substrate size: 6”
  • Current source: 10 nA to 10 mA
