Solutions & Support
In the rapidly evolving landscape of semiconductor engineering, the transition from "Post-Moore" scaling to "More-than-Moore" diversification has fundamentally altered the requirements for test and measurement. As device nodes shrink to the Angstrom scale and architectures shift toward 3D Heterogeneous Integration, the margin for error in characterization has effectively vanished. Today, a probe station is no longer just a mechanical positioning stage; it is the most critical Passive Component in your signal path.
Whether you are characterizing the sub-threshold leakage of a FinFET logic device, managing the thermal runaway risks of a SiC power module, or extracting S-parameters at 110 GHz for 6G applications, the physical interface between your instrument and your Device Under Test (DUT) dictates the validity of your data.
We provide more than just hardware. We act as your Technical Co-Pilot, delivering comprehensive engineering solutions that address the physics of the measurement environment. From vibration isolation and electromagnetic shielding to cryogenic thermal control and automated wafer handling, our mission is to ensure that the data you capture reflects the true performance of your device, uncorrupted by environmental noise.
The Anatomy of Precision: Engineering the Environment
The Physics of Measurement Error: Standard benchtop setups often fail because they ignore the environmental variables that dominate at the micro-scale. In a typical lab environment, ambient vibrations from HVAC systems, electromagnetic interference (EMI) from fluorescent lighting, and thermal fluctuations can introduce noise floors that mask the true behavior of sensitive devices.
Our Solution Architecture: We approach probe system design with a "Physics-First" methodology. We do not just assemble mechanical parts; we engineer an ecosystem of stability designed to eliminate the three primary sources of measurement uncertainty: Mechanical Instability, Electrical Noise, and Thermal Drift.
Fig 1: Our integrated systems combine high-mass granite bases for vibration damping with fully shielded enclosures to create a pristine measurement environment.
To measure currents in the femtoampere (10-15 A) range, simple coaxial cabling is insufficient due to dielectric relaxation and leakage. We implement full Triaxial Guarding from the SMU to the probe tip, ensuring the guard potential matches the signal, effectively eliminating cable leakage and enabling reliable low-level characterization.
Semiconductors must be tested at their operating extremes. Our thermal chucks utilize proprietary PID algorithms and specialized ceramic materials to manage the Coefficient of Thermal Expansion (CTE). This ensures that probes do not "skate" or lose contact during temperature ramps from -60°C to +300°C.
Sub-micron pads require sub-micron stability. Our micro-positioners feature backlash-free lead screws with resolution down to 0.7µm. Coupled with high-mass granite bases and active pneumatic vibration isolation tables, we guarantee stable contact for long-duration reliability testing (WLR).
Application-Specific Methodologies
The Reality of Diversification: There is no "universal" probe station. A setup optimized for the high-voltage requirements of Silicon Carbide (SiC) power devices is fundamentally different from a system designed for the sensitive coherence times of a Quantum Qubit. Attempting to use a generic configuration for specialized applications leads to compromised data fidelity and potential device damage.
We categorize our solutions by the Physics of the Application. We have pre-validated configurations that address the specific electrical, thermal, and mechanical hurdles of each domain.

Semiconductor Characterization
Optimized for Logic, Memory, and Analog devices. Focus is on IV/CV parameter extraction, 1/f flicker noise measurement, and Wafer-Level Reliability (WLR). Our "Dark Box" enclosures provide >100dB shielding to protect sensitive gate oxide measurements.
RF & mmWave Testing
Addressing the challenges of insertion loss and return loss at 5G/6G frequencies. We integrate frequency extenders directly onto the probe platen and utilize micrometric planarization to ensure both Ground and Signal tips contact simultaneously for accurate S-parameter extraction.
Power Electronics (SiC/GaN)
Mitigating the risk of high-voltage arcing (Paschen's Law breakdown). We utilize pressurized chambers and dielectric fluids (Fluorinert™) to allow safe wafer-level testing up to 10kV without flashover, alongside high-current probes for >100A pulses.
Quantum & Spintronics
Exploring the quantum realm requires environments near absolute zero. Our cryogenic systems utilize Liquid Helium (LHe) or Cryogen-free designs to reach 4K, integrated with variable magnetic fields for Hall Effect and spintronic research.
Engineering Services: Lifecycle Support
The Integration Gap: Purchasing capital equipment is only the first step. The complexity of modern testing means that "off-the-shelf" catalog products often cover only 90% of the specific research requirement. The remaining 10%—the custom sample fixture, the specific integration with a Vector Network Analyzer (VNA), or the unique environmental control—is where our Engineering Services team excels.
Custom Engineering (OEM/ODM) Capabilities
We operate an agile "Design-to-Spec" workflow. Unlike rigid catalog vendors, we view our standard platforms as a starting point. If your research involves non-standard substrates (e.g., curved flexible electronics), unique magnetic field orientations, or complex environmental integration (vacuum/gas mixing), our engineering team acts as an extension of your lab to design and manufacture the necessary fixtures.
| Service Aspect | Standard Vendor Approach | The Engineering Partner Approach |
|---|---|---|
| Customization | "Take it or leave it" catalog parts. | Full OEM/ODM support for chucks, holders, and chambers. |
| Integration | Hardware delivery only. | Turnkey Integration with Keysight/Keithley analyzers & drivers. |
| Maintenance | Reactive repairs after failure. | Proactive Annual Calibration & Preventative Maintenance plans. |
| Training | Basic manual handover. | In-depth Application Workshops (e.g., "Low-Noise Probing Techniques"). |
Solving Real-World Engineering Hurdles
Applied Physics Challenges
We don't just sell machines; we solve the physical problems that prevent you from getting accurate data. Here are common challenges we resolve:
The "Femtoampere" Barrier
Problem: Dielectric relaxation in cables and triboelectric noise (generated by cable movement) mask low-level signals.
Solution: We implement rigid triaxial guarding and low-noise chuck dielectrics to lower the system noise floor to < 20 fA.
Thermal Drift in Cryogenics
Problem: As temperature drops to 4K, materials contract, causing probe tips to lose contact with the pad or scratch the surface.
Solution: Our proprietary "Active Probe Compensation" mechanism maintains contact pressure and x-y-z position stability during thermal cycling.
RF Calibration Complexity
Problem: De-embedding cable loss and probe parasitics at 110 GHz is mathematically complex and error-prone.
Solution: We provide integrated ISS (Impedance Standard Substrate) calibration sites on the platen and support SOLT/TRL calibration algorithms directly.
High-Voltage Safety
Problem: Testing SiC at 3kV creates lethal risks for operators and equipment damage hazards.
Solution: Redundant hardware interlocks linked to the dark box door and SMU ensure voltage is cut instantly if the environment is breached.
