MPI TS150-THZ Probe System
With significant expansion of emerging THz applications, such as high-speed 5G communication, satellites, non-invasive spectroscopy, security and surveillance, medical and health care equipment, and short range automotive radar, the need for accurate, reliable and repeatable measurement data has become more crucial than ever. This is especially true for the research and technology development of the devices, integrated circuits and new product building blocks serving the need of these THz applications.
The MPI TS150-THZ is the first, worldwide 150 mm dedicated probe station designed explicitly for mmW and THz on-wafer measurements up to 1.5 THz and beyond. It provides unsurpassed features:
- Seamless integration of any banded, differential or broadband frequency extenders up to 1.5 THz
- Maximum on mechanical stability and repeatability combined with convenient and safety operation
- Minimizing the measurement path for best possible measurement directivity,
The MPI unique air-bearing stage design, with simple single-handed puck control, provides unsurpassed convenience of operation for fast XY navigation and quick wafer loading without compromising accurate and fine positioning capability with the additional fine and accurate 25×25 mm XY-Theta micrometer movement.
Unique Platen Lift with Probe Hover Control™
Measurement accuracy depends on the contact quality first! The highly repeatable (1µm) platen lift design with three discrete positions for contact, separation (300µm), and loading (3mm) with a safety lock utility are all examples of unparalleled functionality incorporated into MPI manual probe systems. These features prevent unexpected probe or wafer damage while providing intuitive control and accurate contact positioning. This capability is especially critical in both high frequency and high power applications in order to achieve the most accurate measurement results.
For TS200 and TS300, additional Probe Hover Control™ comes with hover heights (50, 100 or 150 µm) for easy and convenient probe to pad alignment.
Chuck Z Adjustment
TS150-THZ has 10mm fine chuck Z adjustment, designed to be flexible in the integration of different frequency extenders, like from Rohde & Schwarz, VDI or OML. Extremely beneficial for set-ups using several bended solutions on the same probe system – for easy and fast reset-up.
Multiple Configurations of MicroPositioners
The dedicated and extremely rigid probe platen design accommodates two bolt-down MP80 large area MicroPositioners in east-west configuration. Four port RF measurements or DC biasing is easy possible by having two North and South “bridges” as a standard configuration.
Another MPI pioneering solution on the market – the unique MP80-DX with easy and precise definition down to 1µm of Δl – is the ideal choice for accurate and cost-effective multiline TRL – the only RF calibration method in the mmW and sub-THz range. For more details, visit MPI QAlibria® software.
Various Chuck Options
The TS150-THZ is available with various chuck options to meet different budgets and application requirements such as MPI’s:
- Standard RF Chuck with BNC connector,
- Dedicated mmW Chuck, completely build in special ceramic with high thermal conductivity (>180W/Km), or even
- ERS AirCool RF Chuck (from 20°C to 200°C, or higher) with integrated Gold plated top surface with small vacuum holes
All chucks having two auxiliary chucks built in ceramic material for accurate RF calibration, especially in the range above 40GHz.
Various Optic Options
A dedicated MPI Optics are available with a choice between a single tube MPI SuperZoom SZ10 or the MegaZoom MZ12 with up to 12x optical zoom and more than 45 mm working distance. The small factor of such microscopes is ideal for RF and mmW applications due to space restrictions inherent with the integration of frequency extenders requiring shortest distance to DUT.
