CryoLab

Cryogenic Electronics & Spintronics

CryoLab is a specialised research laboratory within the Institute of Mechanical and Electrical Engineering dedicated to the development, characterization, and validation of cryogenic integrated circuits (CryoCMOS) and spintronic devices. The laboratory supports research on next-generation computing and sensing technologies operating at cryogenic temperatures, enabling the investigation of device behaviour, circuit performance, and system reliability under extreme operating conditions.

Temperature range: 3.5–4 K base temperature, below 4.5 K while probing, 300 K room temperature, 800 K upper limit

Facilities

CryoLab is equipped with advanced cryogenic measurement infrastructure that enables comprehensive electrical and RF characterization of semiconductor devices and integrated circuits over a temperature range extending from below 4 K to 800 K.

Core Instrument – ARS PS-CC Closed-Cycle Cryogenic Probe Station

ARS PS-CC closed-cycle cryogenic probe station in CryoLab

The laboratory features an Advanced Research Systems (ARS) PS-CC Closed-Cycle Cryogenic Probe Station, providing a high-vacuum environment for reliable low-temperature measurements.

Key features

  • Cryogenic temperature range – Stable operation from below 4 K up to 800 K.
  • High-vacuum environment – Minimizes contamination and ensures repeatable measurements.
  • Down-facing cold-tip configuration – Optimized cryocooler orientation achieves base temperatures of 3.5–4 K with excellent thermal stability.
  • Advanced probe thermalization – Multi-stage probe cooling minimizes thermal loading, allowing sample temperatures below 4.5 K even while probing.

Measurement Platform – Spintronics Measurement Setup

Spintronics measurement setup in CryoLab

The CryoLab measurement platform is optimized for precision characterization of spintronic devices and cryogenic integrated circuits. Four elements work together to keep the signal clean at 4 K.

Key features

  • 01 Anti-vibration platform – A precision anti-vibration table suppresses mechanical disturbances and thermal drift, ensuring stable probing with 7 µm DC probe tips and 150 µm-pitch RF probes.
  • 02 Shielded environment – The electromagnetically shielded enclosure minimizes interference, improving signal integrity for sensitive low-noise electrical and RF measurements.
  • 03 High-precision probe station – Accommodates wafers up to 200 mm (8 inches) with precision positioning through a rigid mechanical platform and high-resolution micrometer stages.
  • 04 Measurement instrumentation – Keithley 2450 SourceMeter units for automated current–voltage measurements, a spectrum analyzer for high-frequency characterization of STNOs, MRAM arrays and AMR sensors, and a Python-based automation framework for repeatable workflows.
