Cryogenic Probe System
Enabling scalable, flexible, and high-throughput testing of quantum devices at milikelvin temperatures.
Unlock scalable quantum device testing with our Cryogenic Probe System.
This system consists of four modules:
- CryoStage: Enables precise motion of a set of dies or wafer.
- CryoCamera: Provides alignment and visual feedback.
- CryoProbeCard: Contains the test probes and provides shielding for the quantum device.
- CryoInterface: Allows seamless integration of the camera module into a cryostat and facilitates easy loading.
By enabling motion of sets of dies or wafers at ultra-low temperatures down to millikelvin levels, multiple quantum devices can be tested during a single cryostat cooldown cycle. This significantly increases testing throughput in the most cost-efficient way.
The system offers high-precision X, Y, and Rz alignment, along with Z-axis motion to bring the die or wafer into contact with the test probes. Its modular design simplifies integration into dilution refrigerators.
For cutting-edge quantum chip probing at millikelvin temperatures, the Cryogenic Probe System sets a new standard for scalability, flexibility and cost efficiency.
Eliminate unnecessary die packaging
Testing quantum devices at the bare die or wafer level enables early-stage validation in the manufacturing process. This reduces downstream costs like packaging, while accelerating the development cycle.
10X higher throughput of your test setup
By adding a Cryogenic Probe System to your existing setup you can already achieve a throughput improvement of 7.4X. Throughput gains of up to 14X and potentially even more are expected as qubit measurement times decrease.
See our application note on throughput improvement for more information.
