280I 8" semi-automatic 4 point probe measurement system

Part Number

280I

Designation

8" semi-automatic 4 point probe measurement system

APPLICATIONS

Automatic with Mapping

Description

Semi-automatic 4-point in-line measurement systems on samples ranging from 10mm to 200mm in diameter. Thanks to their motorized chucks, the 280I can map up to 6000 measurement points on surface resistance ranges from 1 mohm/sq to 8E5 Ohm/sq.

Specification:

• Extended range down to 8E11 Ohm/sq.
• Different versions adapted to the different resistance ranges tested
• Several types of mapping: 1pts, 5pts, 9pts, diagonal, Cartesian, custom etc..
• Powerful calculation algorithm
• Edge effect compensation, geometric factor
• SEC II Communication

Application:

- Si, Ge, SiGe, SiC, GaAs, InGaAs, InP, GaN, ZnO, TCOs
- Optoelectronic component
- Nanomaterials
- Sensors, MEMS
- Conductive polymer
- Oxide deposit
- Ceramic & Glass
