MPI Chuck Systems
For different requirements, MPI offers a variety of:
- Coaxial,
- Triaxial,
- RF,
- mmW and
- High-power Chucks
from ambient temperatures through -60°C up to 400°C.
Dedicated top surfaces with many vacuum holes, gold plating or a surface manufactured with pure isolation material are example of the available options.
Wafer probing at different temperatures continues to be a significant challenge. MPI is working closely together with ERS to provide unique software and hardware integration of thermal chucks in all MPI Engineering Probe Systems by offering easy field upgradability, the lowest, total CDA consumption and fastest transition time on the market.
Features & Benefits
AirCool® PRIME Technology
Together MPI Corporation and ERS electronic GmbH designed the New 300 mm Thermal Chuck AirCool
The systems can be configured with lower temperature starting points of -60°C, -40°C, -10°C, 20°C or 30°C and at the higher end points at 200°C or 300°C – all this to tailor the thermal capability to a different requirements and budgets. The filed upgradability path is available for all 200 and 300 mm PRIME chucks systems.
AirCool® Fusion Chiller Technology
The Fusion high-performance chillers offer three default on-site configurable modes, each optimized to meet specific test requirements, plus a Custom mode that allows the key parameters to be defined by the user. With these modes, the AC3 Fusion thermal system is a no-compromise solution for energy-efficient, and flexible wafer testing.
Additional CDA saving, faster transition time, or saving up to 65% energy – is easy and remotely configurable by SENTIO
For tests at -10°C in 200 and 300 mm probe stations, is using a very small chiller making the systems extremely cost-effective to reduce the overall cost of test.
Thermal Chuck Controller
The thermal controller touch screen panel is seamlessly integrated into all MPI’s probe systems and provides extremely convenient operation and also minimizes the test cell foot print.
ERS Patented AC3 Cooling Technology Incorporated
These chucks incorporate the patented AC3 cooling technology and self-management system to purge the MPI’s ShielDEnvironment™ and WaferWallet
Auxiliary Chucks
All MPI RF chucks include two auxiliary chucks built with thick ceramic material for accurate RF calibration and optional “two-in-one” manually controlled AUX for probe cleaning, and/or contact checks.
High Thermal Stability Probe Platen
MPI offers dedicated high thermal stability probe platens to achieve optimal contact quality regardless of temperature range, especially for long-term WLR measurements or for Automated Test over Multiple Temperatures, ATMT™.
Thermal Chuck Temperature Verification
MPI offers two chuck temperature calibration tools – Temperature Calibration Wafer and Temperature Calibration Single Sensor to determine the accuracy of the chuck temperature and calibrate the thermal chuck controller. This ensures the reliability of on-wafer measurement at temperature.
