In the rapidly evolving semiconductor industry, testing precision, efficiency, and cost control have become crucial metrics for evaluating research and production capabilities. Standard testing equipment often falls short when facing complex application scenarios involving extreme temperatures, specialized optical requirements, or integrated spectral analysis. MicroXact addresses these challenges through its deep expertise in customized wafer probing solutions, delivering innovative technologies that significantly reduce testing costs and accelerate time-to-market.

The semiconductor industry is advancing at an unprecedented pace toward smaller, more efficient, and more powerful devices. This evolution presents significant challenges not only for chip design and manufacturing but also for testing processes, particularly in emerging or highly specialized applications:

• Specialized testing environments for optoelectronic devices: Performance evaluation of infrared sensors, focal plane arrays, and solar cell modules often requires specific external light source simulation conditions. These may include blackbody radiation, solar simulators, various frequency lasers (pulsed, modulated, or continuous wave), and even laser trimming or cutting applications. Standard probing stations struggle with precise optical alignment, stable light source coupling, and effective shielding from ambient light interference.
• Device performance analysis under extreme temperatures: As devices operate at higher frequencies (above 110GHz) and require testing in cryogenic (liquid helium range) or high-temperature environments, traditional temperature-controlled probing equipment faces challenges in heat dissipation, thermal stability, and material compatibility. This is particularly true for devices with high thermal loads or large test article thermal mass.
• Complex requirements for integrated spectral analysis: Advanced material research and device characterization often require high-precision spectral measurements (such as Raman spectroscopy or fluorescence spectroscopy) while applying electrical bias, current, or external magnetic fields. This demands probing stations that not only provide precise electrical stimulation but also seamlessly integrate with high-resolution spectrometers while maintaining optical path stability and signal purity.

MicroXact combines advanced engineering with deep application insight to deliver probing systems that meet or exceed expectations. Their customized solutions focus on several key areas:

For optoelectronic device testing requiring external light sources or specific environmental simulations, MicroXact offers highly flexible solutions including:

• Comprehensive light source coupling: Custom-designed coupling devices for blackbody radiation sources, solar simulators, or various laser sources, ensuring stable, precise, and efficient optical paths through customized fiber couplers, collimating lens assemblies, filter systems, and precise positioning mechanisms.
• Custom optical system integration: Integration of customer-specified microscope objectives, beam splitters, and detectors for applications requiring high-resolution imaging or specific spectral responses, enabling simultaneous electrical and optical characterization.
• Laser trimming and cutting application support: Precise control of laser energy, position, and duration for wafer-level device processing with real-time electrical parameter monitoring.

Extreme temperature testing is critical for semiconductor device validation, particularly for THz frequency devices and applications simulating harsh operating environments. MicroXact offers both standardized extended-temperature probing stations and highly customized solutions:

• Standard extended temperature range stations: Covering common low-temperature (4K to 300K) or high-temperature (300K to 600K) testing needs with stable performance and user-friendly operation, featuring optimized thermal conduction, radiation management, and material stability.
• Custom extreme temperature solutions: Addressing specialized requirements including high thermal load device testing, ultra-high frequency device characterization (110GHz+), and large thermal mass sample handling through advanced thermal design, PID control algorithms, and multi-point temperature monitoring.

For materials science and device physics research requiring combined electrical stimulation and spectroscopic measurements, MicroXact's probing stations demonstrate exceptional adaptability:

• Seamless spectrometer integration: Designed with interfaces and space for various spectrometers (Raman, fluorescence), ensuring optimal optical path alignment for efficient signal transmission and collection.
• Synchronous electrical and spectral measurements: Providing stable, adjustable electrical stimulation (DC bias, AC signals, high-current injection) while simultaneously acquiring spectral data under specific excitation wavelengths, crucial for studying field-induced phase transitions, carrier dynamics, and defect properties.
• External magnetic field environment support: Integration with electromagnetic or permanent magnet systems for studying magnetic field effects on material properties while maintaining electrical measurement integrity and optical signal quality.
