Large Ultra Low Vibration Chip-scale Probe Station for Conducting High-Accuracy Measurements at True 4K Cryogenic Temperatures

The HPD IQ2000 is a superior 4 K solution to meet all your probing needs in an ergonomic, low vibration system. This chip-scale prober addresses problems such as long turnaround times, high noise, and low signal capabilities. FormFactor’s extensive knowledge of probing solutions and cryogenic systems puts us in the best position to help you meet your goals. 

The IQ2000 incorporates a variety of thermal isolation techniques to fully harness the available cooling power to achieve a genuine 4 K system with temperature stability down to 5 mK. 

Mechanical vibration poses a significant challenge in probing applications, potentially leading to sample damage and introducing noise into measurements. Triboelectric noise can further contaminate signals when mechanical vibrations propagate through cables. This system ensures a probe-to-DUT displacement of less than 50 nm RMS. 

Designed with customization in mind, the IQ2000 offers a multitude of configurable ports to facilitate signal transmission to your sample. Each stage plate boasts multiple easily accessible vacuum feedthroughs and numerous light-blocking ports, simplifying the integration of various signal capabilities (DC, RF, FO) as per your requirements. 

The HPD IQ2000 delivers genuine 4 K measurement capabilities across all probing operations within an ultra-low vibration environment. Its robust and dependable nature, coupled with an extensive range of optional features and multiple upgrade paths, ensures its suitability for diverse future needs. 

Applications: Photonic QC, Spin QC, Cryo-CMOS, Scanning Microscopy 

Cryogenic Temperatures

  • Fully isolated experiment space for true 4K temperatures during probing
  • Cryogenic positioners to provide large travel ranges without warming up the device
