What Atomica Corp does

Atomica Corp, founded in 2000 (originally as Innovative Micro Technology) and rebranded in November 2022 under majority ownership of Cerium Technology Ventures, operates the largest pure-play MEMS foundry in the United States from a 30,000-square-foot Class 100 cleanroom on a 13-acre, 130,000-square-foot site in Goleta, California, near UC Santa Barbara. The company provides custom MEMS, photonics, sensor, and biochip wafer fabrication across 6 and 8 inch wafers, organized into 21 application platforms spanning photonics (interposer, microlens, micromirror, silicon optical bench, TGV, TSV, V-groove, waveguide, WLP), sensors (accelerometer, gyroscope, gas, magnetic, pressure, diaphragm, comb drive), biotechnology (microfluidic channels, pumps, valves, microneedles, microarrays), and general MEMS. Underpinning these platforms are 12 core manufacturing capabilities — design and modeling, photolithography (including 3D greyscale), deposition, plating, annealing/oxidation, dry and wet etching, wafer bonding (hermetic, vacuum, multi-wafer), wafer backend, metrology, and testing — with proprietary process technologies including DRIE Bosch silicon etch, hermetic wafer-level packaging achieving >99% hermeticity, and AI-enhanced metrology.

The company's go-to-market is direct enterprise sales targeting six verticals — telecommunications, automotive, healthcare/life sciences, aerospace and defense, industrial, and consumer — with named engagements such as the Miltenyi Biotec microfluidic cell-valve partnership. Pricing is quote-based, project-specific, and contracted on multi-year terms, leveraging engineering consultation as the primary demand-generation channel. Atomica holds ISO 9001 certification (since 2006) and ITAR registration, making it one of the few domestic foundries qualified for defense and aerospace MEMS work.

Atomica is privately held and controlled by Cerium Technology Ventures, which led a $30 million Series C in November 2022 alongside Novo Tellus Capital Partners and St. Cloud Capital; Eldon Klaassen serves as CEO and Chairman, with a management team recruited from Allegro Development, Knowles Precision Devices, SunEdison, Wolfspeed, Menlo Micro, and Analog Devices. The company has continued to expand its service surface, adding Simulation and Modeling in April 2025 and an AI Optical Connectivity Platform in June 2026 to position itself for the optical interconnect bottleneck in AI infrastructure.
