Who we are

As a leader in advanced process control, UnitySC delivers semiconductor metrology and inspection solutions that support the advancement of the semiconductor industry’s heterogeneous integration roadmap. Specifically, our integrated systems target the semiconductor advanced packaging, power semiconductor and MEMS markets, focusing on applications such as through silicon via (TSV) fabrication, fan-out wafer-level packaging, substrate control, hybrid bonding and chemical mechanical planarization (CMP) processes.

We work in collaboration with our customers to develop and implement disruptive semiconductor metrology and inspection systems that provide industrialized solutions to process control problems, enabling them to better understand their processes, manage and improve their yields, and grow their businesses. Our customers include the largest foundries, integrated device manufacturers, outsourced semiconductor assembly and test service providers, and R&D centers.

UnitySC’s integrated process control systems leverage multiple optical techniques for semiconductor metrology and inspection, including:

  • Time-domain infrared optical coherence tomography (OCT)
  • Full field interferometry (VSI and PSI)
  • Phase-shifting deflectometry
  • Chromatic confocal microscopy
  • Laser Doppler velocimetry
  • Reflectometry
  • Infrared microscopy

Our full product portfolio includes:

  • The TMAP Series, for accurate and repeatable wafer geometry measurements such as thickness, total thickness variation (TTV), and the shape and flatness of mono- and multilayer substrates for all kinds of materials.
  • The NST Series, a noncontact full-field metrology solution based on optical microscopy, enabling surface topography measurements at the nanoscale.
  • The 4SEE Series, a modular platform for all-surface inspection that ensures wafer frontside, backside and edge quality by detecting, counting, and binning particles and defects during the wafer manufacturing process.

UnitySC’s visionary approach fosters progress for people. We are differentiated by our IP-protected semiconductor metrology and inspection solutions, along with our reputation as a company with which people like to work. We strive to deliver added value to our customers by implementing our technology expertise in a manner that solves their semiconductor manufacturing problems.
