Infinity Probe
High-frequency performance with low, stable contact resistance on aluminum pads
Ideal for device characterization and modeling, Infinity probe combines extremely low contact resistance on aluminum pads with unsurpassed RF measurement accuracy for highly reliable, repeatable measurements. Proprietary thin-film and coaxial probe technology reduces unwanted couplings to nearby devices and transmission modes.
Features
- Lithographic thin-film construction
- Excellent crosstalk characteristics
- Non-oxidizing nickel alloy tips
- Innovative force delivery mechanism
- 40 to 220 GHz versions
- GSG, SG, GS, GSGSG, GSSG configurations
- 50 to 250 µ m pitches
- High current version (2 amp) available
Advantages
- Superior field confinement reduces unwanted couplings to nearby devices and transmission modes
- Superior measurement accuracy and repeatability
- Small scrub minimizes damage to aluminum pad
- Typical contact resistance < 0. 05 Ohm
- Save valuable wafer space and reduce pad parasitics by being able to shrink pad geometries to 50 x 50 µ m
