Semiconductor Characterization
In advanced semiconductor R&D, accurate data is the currency of innovation. Standard test setups often struggle with noise floors, thermal instability, or parasitic effects when characterizing next-gen devices like SiC, GaN, or quantum materials. AIMRSE Semiconductor Characterization Solutions eliminate these variables. We provide modular, high-precision probe systems capable of extreme environments—from cryogenic temperatures to high-voltage power testing. We bridge the gap between raw device physics and reliable, publishable data, ensuring your research validates your design.
Critical Testing Challenges
Before selecting a solution, it is essential to understand the common pitfalls in semiconductor characterization that can compromise data integrity.
Signal Integrity & Noise
Measuring femto-ampere (fA) leakage currents requires more than just a sensitive meter. Environmental noise, cable leakage, and triboelectric effects can obscure real data. Our solutions integrate Triaxial Cabling and guarded fixtures to lower the noise floor, ensuring you capture the true IV/CV characteristics of your device without interference.
Extreme Environment Control
Device performance shifts dramatically under temperature stress or magnetic fields. Standard benches cannot simulate space, automotive, or quantum conditions. Our Cryogenic and Magnetic Field systems provide stable, vibration-isolated platforms that maintain precise thermal and magnetic conditions throughout long-duration tests.
High Power & Safety
Testing Wide Bandgap (SiC/GaN) devices involves high voltages that risk arcing and equipment damage. Conventional probers lack the insulation and safety interlocks needed for kV-range testing. Our High Power Systems feature specialized shielding and safe-contact architectures to protect both your expensive wafers and your operators.
Core Applications: Precision IV/CV & WLR
Our solutions are optimized for the most critical semiconductor characterization tasks, ensuring high fidelity from early device modeling to process qualification.
fA‑Level Leakage Measurement
Utilizing fully guarded thermal chucks, micro‑positioners, and triaxial interconnects to guarantee a noise floor in the femto‑ampere range. Essential for evaluating dark current and gate leakage in advanced logic and memory devices.
Low Parasitic Capacitance CV
Optimized signal paths eliminate parasitic effects, ensuring precise Capacitance‑Voltage (CV) measurements even at high frequencies. Ideal for characterizing advanced gate stacks and RF devices.
High Stress Endurance (HTRB/TDDB)
Engineered for High‑Temperature Reverse Bias, Time‑Dependent Dielectric Breakdown, and electromigration testing. Our thermal solutions maintain ±0.1°C stability over hundreds of hours without drift.
Safety & Automation for High Voltage
Integrated safety enclosures and anti‑arcing environments provide secure probing for kV‑level breakdown testing. Vital for SiC and GaN power device qualification in automotive and energy sectors.
System Architecture Highlights
AIMRSE platforms are engineered with four core pillars to ensure precision, stability, and safety in every measurement.
Why Precision Architecture Matters
Standard probe stations are cost-effective, but they often become the bottleneck in high-performance characterization. We solve these critical engineering limitations.
Sub-Micron Positioning
Modern wafers have shrinking pad sizes. Standard positioners often lack the repeatability needed. We utilize high-stability Micro-Positioners to ensure repeatable contact placement, critical for multi-site testing and avoiding pad damage on expensive wafers.
Thermal Stability
Temperature drift ruins IV/CV curves. Without expert thermal design, measurements fluctuate. Our Thermal Chucks maintain temperature uniformity within ±0.1°C across the entire wafer surface, from liquid nitrogen cooling to resistive heating.
EMI & Vibration Isolation
External noise corrupts fA-level signals. Standard benches transmit floor vibrations. We counteract this by integrating proprietary Anti-Vibration Platforms and Faraday cage compatibility to isolate your DUT from mechanical and electromagnetic interference.
Core Advantages
Ultra‑Low Noise & Femto‑ampere Sensitivity
Environmental noise and cable leakage often bury true device characteristics. Our Low‑Noise Configuration combines triaxial cabling, guarded thermal chucks, and full Faraday shielding to achieve a verified noise floor in the femto‑ampere (fA) range. Capture real leakage currents in advanced logic (2nm GAAFET) and high‑k gate stacks without parasitic artifacts.
±0.1°C Thermal Uniformity Across Full Wafer
Temperature drift distorts IV/CV curves and reliability lifetime extrapolations. Our thermal chucks deliver wafer‑level uniformity of ±0.1°C from cryogenic (4K) up to 400°C, with integrated guarding to eliminate leakage currents. Whether performing HTRB or TDDB, you get stable, drift‑free data over hundreds of hours.
High‑Voltage Arcing Prevention (Up to 10 kV)
Standard probers risk flashover and equipment damage when testing SiC/GaN devices. Our High Power Systems utilize pressurized chambers and dielectric fluid options to safely perform wafer‑level testing up to 10 kV without arcing. Integrated safety interlocks protect both your operators and your valuable wafers.
Modular Architecture – From Manual to Fully Automated
One platform adapts to your evolving needs. Start with a manual probe station for failure analysis, then upgrade to full automation with motorized platen, temperature control, and RF/microwave capabilities up to 110 GHz. Seamless integration with Keysight, Tektronix, and other analyzers ensures you never outgrow your system.
