MPI Corporation Unveils Advanced 250 GHz Testing Solution

MPI Corporation, a prominent global leader in semiconductor testing solutions, has made a significant leap in high-frequency testing by introducing its new 250 GHz wideband probe solution. This latest offering integrates advanced technologies for precise measurements in next-generation semiconductors and sub-THz applications. The innovative system enhances performance in characterizing S-parameters at wide bandwidths, effectively supporting the growing demands of the semiconductor industry from AI to 5G/6G technologies.

A Milestone in High-Frequency Measurement

Launched on September 11, 2025, the new 250 GHz probe solution combines MPI’s extensive expertise in sub-terahertz probing with the new frequency extenders from Keysight Technologies—specifically the Keysight NA5305A/7A PNA-X. MPI's TITAN™ probes are central to this solution, enabling accurate and high-performance testing critical for the advancement of semiconductor technologies. The inclusion of state-of-the-art four-terminal measurements allows for unmatched precision and reliability, ensuring that developers can push the envelope of existing semiconductor capabilities.

Stojan Kanev, General Manager of MPI's Advanced Semiconductor Test division, emphasized that “MPI has been at the forefront of demonstrating live single-sweep calibration and on-wafer measurements up to 250 GHz in both single-ended and differential modes.” He highlighted that this achievement builds on previous solutions that extended wideband probing capabilities beyond 200 GHz.

Features of the 250 GHz Solution

The new solution is engineered to maximize test accuracy. It includes several key features:

• - Ultra-Low Insertion Loss: Ensures high-quality signal integrity across the entire frequency range.
• - Unique Tip Visibility: Offers mechanical stability for easy alignment, resulting in consistent data capture.
• - Retractable Tip Protector: Enhances safety during handling of the probes.
• - Available Configurations: The probes come in single (GSG) and dual (GSGSG) configurations, optimized for various device types.

These TITAN™ probes are fully integrated into MPI's probe station platforms, allowing for controlled temperature measurements with minimal user intervention, thus maximizing system repeatability.

Integration with Keysight

Keysight Technologies’ David Tanaka remarked on the mutual benefits of this collaboration, stating, “Continuous innovation from MPI in high-frequency wafer probing plays a vital role in extending the measurement capabilities of our broadband vector network analyzer platform.” The synergy between MPI's advanced probing technology and Keysight’s leading instrumentation ensures that customers receive the precise and repeatable measurements required for cutting-edge applications.

Meeting Evolving Needs in Semiconductor Testing

With innovations like artificial intelligence and high-speed optical communications leading the charge, the demand for highly responsive testing and measurement tools is paramount. MPI’s 250 GHz wideband probe system meets this demand by allowing:

• - Fully calibrated single-sweep wideband S-parameter measurements up to 250 GHz.
• - Support for both wideband and nonlinear modulated measurement techniques.
• - Seamless integration with leading test instruments for a complete measurement chain.

The newly developed systems are already operational in evaluation environments at key client locations. Demonstration systems can be experienced at MPI’s locations in Taiwan and the United States. Moreover, the solution will be showcased during the European Microwave Week (EuMW) 2025, in Utrecht, Netherlands, where a live installation will be presented.
