As RF and microwave devices move to higher frequencies, wider bandwidths, and more complex designs, wafer test is becoming essential to maintaining performance, yield, and time-to-market. From 5G frontends to emerging mmWave and sub-THz applications, engineers need precise, repeatable measurements early in development—without adding unnecessary complexity.

To meet these demands, FormFactor and Rohde & Schwarz are expanding their long-standing collaboration through FormFactor’s MeasureOne partner program. The result is a validated, turnkey on-wafer RF test solution that combines best-in-class wafer probing with industry-leading RF instrumentation, supporting everything from early design verification to high-volume production.

 

Why On-Wafer RF Characterization Matters More Than Ever

Modern RF devices are no longer simple, discrete components. They are highly integrated systems operating across wide frequency ranges, often with tight performance margins. That level of complexity makes on-wafer testing essential, not just for validation, but for keeping innovation moving.

By characterizing devices at the wafer level, engineers can:

  • Identify performance issues before costly packaging steps
  • Correlate design models with real-world measurements earlier
  • Improve yield through faster root-cause analysis
  • Shorten development cycles by enabling rapid iteration

In applications like 5G, automotive radar, and high-frequency communications, even small measurement errors can create big problems downstream. That’s why tightly integrated wafer-level RF test solutions aren’t optional anymore, they’re foundational.

 

A Fully Integrated RF Test Workflow—From Probe Tip to Instrument

FormFactor and Rohde & Schwarz have collaborated for years to simplify and strengthen on-wafer RF measurement. Through MeasureOne, that collaboration is now delivered as a validated solution ready for production environments.

Rohde & Schwarz contributes a comprehensive portfolio of RF and microwave instrumentation, including high-performance vector network analyzers such as the R&S ZNA, ZNB, ZNBT, ZVA, and ZNL families. These platforms deliver highly accurate S-parameter measurements and can extend into the THz range with frequency converters. Complementary tools, including signal and spectrum analyzers, signal generators, and calibration frontends, support complex RF characterization workflows.

FormFactor integrates these capabilities with advanced wafer probing technologies, including:

  • Manual, semi-automated, and fully automated probe stations
  • High-frequency RF and mmWave probes
  • Precision probe positioners for repeatable contact
  • Advanced thermal subsystems for temperature-controlled testing
  • Calibration and measurement optimization tools

The result is a seamless hardware and software environment designed to deliver fast, accurate, and repeatable RF measurements across the entire wafer test cycle.

 

Reducing Integration Risk in Advanced Wafer Test Environments

One of the biggest challenges in RF wafer testing isn’t the measurement itself, it’s getting all the pieces to work together. Engineers often spend valuable time aligning instruments, calibrating setups, and troubleshooting inconsistencies between components.

MeasureOne removes much of that burden by delivering a pre-validated solution where everything is designed and tested to work together from the start.

This approach helps teams:

  • Minimize setup time and integration effort
  • Reduce measurement variability across systems and sites
  • Lower overall cost of test through improved efficiency
  • Increase confidence in data used for design and qualification

Instead of building test systems from scratch, engineers can focus on what matters, understanding device performance and moving development forward faster.

 

Accelerating Time-to-Market for Next-Generation RF Devices

As semiconductor roadmaps push into mmWave and beyond, development timelines are tightening while technical requirements continue to increase. Test strategies have to keep up.

By combining FormFactor’s precision wafer probing with Rohde & Schwarz’s RF measurement expertise, this expanded partnership helps enable:

  • Faster design verification through highly repeatable measurements
  • Improved correlation between R&D and production test environments
  • Scalable test solutions that grow with device complexity
  • Greater throughput without compromising accuracy

As Jens Klattenhoff, SVP and GM of the Systems Business Unit at FormFactor states:

By expanding our collaboration with Rohde & Schwarz through the MeasureOne program, we are delivering integrated on-wafer RF test solutions designed to help customers reduce risk, improve efficiency, and accelerate development.

 

Enabling the Future of RF Innovation

As RF technologies continue to evolve, driven by 5G, AI infrastructure, automotive radar, and next-generation wireless standards, the demands on wafer testing will only increase.

Engineers need solutions that deliver:

  • Precision at high frequencies
  • Repeatability across environments
  • Scalability from R&D to production
  • Confidence in every measurement

Through MeasureOne, FormFactor and Rohde & Schwarz are delivering exactly that: a proven, integrated on-wafer RF test solution built for the next wave of semiconductor innovation.
