4-point-resistivity measurement system
including:
- State-of-the-art laptop equipped with state-of-the-art software for accurate 4-point-measuring control with licenses & updates for at least the next 5 years. The Laptop must be fully capable to run the control software using as operating system Windows 10 or higher. The specified system accuracy needs to be better than 99 %. The software has to manage tests automatically, displays results graphically (average, standard deviation) and enable export of the data (excl files).
- Probe stand including an ultem vacuum chuck for 200 mm wafer and a manual x-y motion control stage with digital positioning readout. The probe stand has to be pre-wired and ready to connect to the source meter.
- Probe head including 2 different four-point probes:
- tungsten carbide as probe tip material
- 85 g pressure on each tip
1) 0.0625 inch tip spacing with 0.005 inch tip radius
2) 0.040 inch tip spacing with 0.0016 inch tip radius
- Source meter
- resistivity range: 10 µ?/sq - 100 M?/sq
- voltage range: 20 mV - 200 V
- current range: 10 nA - 1 A
- 6½ digits
- graphical display
- Necessary state-of-the-art cable connections between all the system components to guarantee accurate operation with deviations of results less than 1 %.
Resistance calibration standard
- 200 mm bare silicon wafer (lapped, polished)
- p-type (Boron) doped
- 710 µm thickness
- 10 Ohm.cm, 141 Ohm/sq
- Certificates of calibration (resistivity, sheet resistance and thickness)
On-site installation and training
- The tool installation at IHP must include an one-day user training at IHP in-person.
- The technical & process acceptance test at IHP must contain measuring the resistivity and sheet resistance of the calibration wafer of position 2 and one IHP standard wafer having a resistivity of 8-12 Ohm.cm with a deviation of < 1 %.
