Published on 11 December 2023


Manufacturing innovative devices for the industry

With a world class microelectronic equipment pool, CEA-Leti’s cleanrooms help develop procedures involved in manufacturing innovative components and electronic circuits compatible with the industry’s high-volume requirements. CEA-Leti's cleanrooms are ISO 9001 certified and are in operation 24h/7.

More than 600 CEA-Leti experts in microelectronic processes (deposition, photolithography, etching, planarization, bonding, etc.), equipment, and materials are developing technologies and components for future products in collaboration with many industrial partners (lab-to-fab model).

  • resilient, competitive manufacturing processes with an optimized number of stages and environmental impact;
  • customized, ready-to-use multistage modules for smooth transfers to our industrial partners’ production machines;
  • state-of-the-art prototypes in terms of miniaturization, energy efficiency, speed, frequency, and performance.

The platform relies on a pool of nano-characterization equipment that is unique in Europe, including electron microscopy, X-ray diffraction, magnetic resonance, ion beam processes.

​What expertise is provided to industrial stakeholders?

• Design and simulation of innovative circuits and components
• Development and validation of processes and process engineering
• Early-stage lifecycle analyses in R&D cycles
• Prototyping, controls, tests, and advanced characterization of substrates, components, and circuits
• Assessments and improvements to microelectronics equipment in conjunction with their suppliers
• Continuous transfers with our partners via the lab-to-fab model

How to work with the cleanroom platform

CEA-Leti’s teams support the needs of its industrial partners across all or some stages of development, using bilateral contracts. Each collaboration is subject to an intellectual property agreement establishing the confidentiality of all work.

The platform works with more than fifty industrial partners:

• Microelectronics stakeholders: STMicroelectronics, Soitec, Infineon, Intel, etc.

• Fabless companies and equipment manufacturers: ASML, Applied Materials, Lam Research, Screen, KLA, EVG, ASM, etc.

• Industrial users: telecoms, photonics, automobile equipment manufacturers, etc.
