The Hummingbird Scientific SEM MEMS Heating + Biasing Sample Holder enables simultaneous high-temperature heating and electrical biasing during in-situ SEM experiments. Microfabricated MEMS chips deliver closed-loop heating up to above 1000 °C with on-chip temperature sensing, while nine direct-chip electrical contacts support electrical biasing and electrical measurements. Screw-free direct MEMS chip loading simplifies sample exchange and provides fast, repeatable electrical and thermal connections for high-temperature in-situ SEM workflows.
The system supports operando studies of semiconductor devices, solid-state battery materials, catalysts, phase-change materials, low-dimensional materials, nanoparticles, and thin films. Simultaneous heating and electrical biasing enable direct correlation of temperature-dependent surface morphology, chemical composition, and electrical response during phase transformations, electrical transport, degradation, diffusion, and failure analysis.
From routine characterization to application-specific experiments, the platform is engineered to expand experimental capability as research evolves. The holder is optimized for versatility in SEM environments with multiple unique detectors including scattered (BSE and SE) and transmission (STEM) oriented around the sample stage inside of an evacuated chamber. Standard MEMS Heating, Electrical Biasing, Heating + Biasing, and FIB lift-out MEMS chips support a broad range of experimental requirements, while cross-compatible MEMS chips enable seamless workflows across Hummingbird's SEM, TEM, and synchrotron X-ray platforms. Custom MEMS chip designs further extend the platform to support emerging materials, novel device architectures, and specialized in-situ microscopy applications.

The SEM MEMS Heating + Biasing Sample Holder combines Hummingbird Scientific's in-house microfabricated MEMS chips, direct electrical contacts, and closed-loop temperature control to perform simultaneous high-temperature heating and electrical biasing inside the SEM. Samples are mounted directly onto a MEMS chip and inserted into the holder using a screw-free loading mechanism, enabling fast, reproducible experiment setup.
During operation, the MEMS microheater delivers temperatures up to above 1000 °C, while on-chip 4-point resistance sensing enables closed-loop temperature control for stable real-time imaging and analysis. Heating + Biasing MEMS chips support simultaneous thermal and electrical stimulation, while biasing MEMS chips dedicate all nine contacts to electrical measurements when heating is not required.
EDS-compatible SEM analysis allows researchers to correlate morphology, elemental information, temperature, and electrical stimulus during the experiment.


Load MEMS chips quickly with reliable electrical contact and simplified experiment setup

Load MEMS chips directly into the holder using a screw-free insertion mechanism with spring-loaded electrical contacts. Eliminate delicate alignment, wire bonding, and complex mounting procedures while establishing consistent electrical contact. This simplified loading process reduces setup time, improves experiment reproducibility, and enables rapid sample exchange between experiments.

Perform low-noise in-situ electrical measurements with nine direct chip electrical contacts and individually shielded coaxial cables

Advanced electrical characterization requires stable, low-noise signal transmission throughout the experiment. Individually shielded coaxial cable inside and out of the holder and nine direct-chip electrical contacts minimize electrical interference while supporting simultaneous heating, electrical biasing, multi-terminal measurements, and independent sample grounding for greater experimental flexibility.

Achieve stable high-temperature experiments with rapid MEMS heating and precise temperature control alongside concurrent biasing
