UNISERS

High-Level Overview

UNISERS is a Zurich-based semiconductor metrology startup founded in 2019 that develops innovative wafer inspection tools using surface-enhanced Raman scattering (SERS) and vacuum-based plasma coating technology to detect and characterize nanoparticles down to 8nm on wafers.[1][2][3][6] The company serves semiconductor manufacturers by identifying contamination sources in process chemicals, high-purity components, and production tools, solving the critical problem of yield loss—billions in annual waste from ineffective contamination control—and enabling faster root-cause analysis for higher chip yields and reduced environmental impact like water and CO2 savings.[1][3][4][5] With $14M in Seed VC funding raised in February 2023 from Intel Capital, M Ventures, Swisscom Ventures, and RSBG Ventures, UNISERS has built prototypes for 300mm wafers, delivered demonstrators to chipmakers, and gained early traction through customer testing in its Zurich lab.[3][4][5][6]

Origin Story

UNISERS emerged from research at ETH Zurich, where Dr. Ali Altun, CEO and co-founder, discovered the core SERS enhancement principle during his work, drawing on his prior semiconductor industry experience in Korea to recognize its potential for contamination control.[3][6] In 2019, Altun partnered with mechanical engineer Timo Schneider, Chief Engineer and co-founder, to incorporate UNISERS AG in Zurich with minimal initial funding; they rapidly prototyped tools capable of processing 300mm wafers and demonstrated unique detection of invisible contaminants to industry customers.[1][6] A pivotal moment came in February 2023 with a $14M Seed round led by Intel Capital, enabling commercial product acceleration and highlighting the technology's shift from research-focused SERS (long limited by lack of universality) to practical, broad-spectrum application.[3][4][5][6]

Core Differentiators

• Nanoparticle Detection Sensitivity: Detects particles down to 8nm (sub-10nm via SERS) with molecular fingerprints for chemical identification (e.g., polymers), surpassing elemental-only analysis in competitors like Quantamap or Parsum.[1][2][3][4]
• Universal Applicability: Vacuum-based plasma coating makes SERS work on any wafer type or surface, enabling high-speed optical inspection of diverse contaminants invisible to state-of-the-art tools.[3][6]
• Root-Cause Speed and Yield Impact: Monitors defectivity in individual process chemicals/tools, slashing time to source identification vs. traditional methods, with even 1% yield gains saving billions in resources.[2][3][5]
• In-House IP and Prototyping: Fully owns IP, develops proprietary products (SEPS for size/type, SERS for molecular ID), and supports 300mm wafers via self-built prototypes in Zurich lab for customer testing.[3][4][6]
• Sustainability Edge: Reduces chip waste (>50% in processes), cutting CO2, water, and emissions, backed by industry investors like Intel Capital.[3][5]

Role in the Broader Tech Landscape

UNISERS rides the AI-driven semiconductor boom, where shrinking nodes (e.g., 2nm/1nm) amplify contamination sensitivity, causing massive yield excursions in advanced fabs amid chip shortages and geopolitical supply strains.[2][5] Timing is ideal post-2023 funding, as fabs prioritize yield optimization for high-NA EUV tools and ultrapure chemicals; UNISERS' molecular-specific monitoring fills gaps in IRDS yield studies and proactive particle control.[4][5] Market forces like exploding demand for chips in AI/data centers (e.g., Nvidia/TSMC ecosystems) and sustainability mandates favor it, influencing the ecosystem by enabling greener fabs and faster defect resolution across the value chain—from chemical suppliers to end-producers.[2][3][5]

Quick Take & Future Outlook

UNISERS is poised to become a must-have for contamination control, with 2023 funding fueling 2023-2024 commercial deliveries to leading fabs and expansion into more use cases like liquid chemical testing.[4][5] Trends like sub-2nm nodes, AI compute scaling, and net-zero mandates will amplify demand, potentially driving Series A and global adoption via investor networks (Intel, M Ventures).[2][3][5] Its influence may evolve from niche metrology to ecosystem standard, humanizing chip production by turning "invisible" defects into actionable insights—much like Altun's ETH breakthrough transformed research into yield-saving reality.[6]
