FormFactor - Cascade Infinity Waveguide Probe - Repeatable measurements up to 500 GHz with improved crosstalk performance
-
Probe loss is 3 dB typical between 140 and 200 GHz, S11/S22 15 dB typical
-
Reduced unwanted couplings and transmission modes
-
Able to shrink pad geometries to 25 x 35 µm (best case)
-
Typical contact resistance < 0.05 Ω on Al, < 0.02 Ω on Au
-
WR15, WR12, WR10, WR8, WR6, WR4, WR3, and WR2 bands available.
With the advent of Silicon CMOS and SiGe technologies, devices are getting smaller and faster. Test engineers need to validate the performance of their devices up to 500 GHz and beyond in some cases. This component/on-wafer probing solution is designed to meet the challenges of high-frequency probing for advanced on-wafer modeling and characterization while providing low, stable contact resistance on 50 micron pads. At 500 GHz the toughest problem is electrical fields around the probe. The Waveguide Infinity Probe’s new membrane GSG contact tip design reduces stray EM fields near probe tip. Control of EM fields near the tip allows repeatable measurements up to 500 GHz and improved crosstalk performance between the tips.

More Product Information
-
Long holding time: 80 hours with 10 STP liter He-3 gas
-
Stable He-3 pot temperature: Separate sippers for 1K pot and the charcoal sorb cooling line
-
Sample can be loaded or removed when the cryostat is cold

-
Multiple operation modes: He-3 cryostat can be operated without pumping the 1K pot (referred to as 4K operation mode)
-
Ease of use – Less experienced operators can perform an RF calibration up to 500 GHz by simply pushing a button. This reduces the need of experienced users full time on each system.
-
Reduced Soak Time – The system will automatically re-align the probes to the pads if they drift from alignment. This reduces test time and increases throughput.
-
Unattended Use – Measurements can be left running over night or the weekend, testing all devices on the wafer, and at different temperatures without the need of an operator.
-
Calibration Monitor and Re-calibration – System will
continuously monitor calibration drift, and automatically re-calibrate the system should the drift exceed a predefined limit.
-
Customizable configuration up to 25 contacts: RF, Eye-Pass power, ground, logic
