About PTA

The PTA (Upstream Technological Platform) is a state-of-the-art Class 1000 cleanroom facility, created through a strategic collaboration between IRIG (CEA’s Institute for Nanosciences and Cryogenics) and LTM (Laboratory for Microelectronics Technologies, a joint effort by CNRS, UJF, and INP). Covering a total of 700 m²—split evenly between the CEA site and the Grenoble INP location within the CIME (InterUniversity MicroElectronics and Nanotechnologies Centre)—the platform is engineered to support advanced projects in nanosciences and micro-nanotechnologies.

Our facility boasts a comprehensive array of tools, including advanced equipment for lithography, deposition, and etching. These capabilities enable the precise integration of nano-objects and nanomaterials, as well as the patterning of ultra-thin layers down to the nanometric scale. Designed with versatility in mind, the PTA accommodates substrates ranging from tiny 5 x 5 mm² samples to full 100 mm wafers - and upto  200 mm depending equipement process - while ensuring rigorous contamination control.

The PTA supports a broad spectrum of research areas—from nanoelectronics, MEMS & NEMS, magnetism, and spintronics to the integration of nanomaterials, nano-objects, and photonics. Our mission is twofold: to provide researchers with the cutting-edge tools and expertise needed to drive innovation, and to offer industrial partners a dynamic environment to develop their semiconductor projects.

Built on principles of flexibility, accessibility, and ease of use, the PTA is managed through a unique partnership that merges the complementary expertise of INAC and LTM. This collaborative approach guarantees that users benefit from a state-of-the-art facility combined with tailored support, fostering an optimal setting for both pioneering research and industrial development.

How to use Our Facilities

At PTA, our platform is designed to empower advanced micro- and nano-fabrication projects with flexible project management solutions.

Direct Access
Engineers, researchers, technicians, students, and industry professionals can independently operate our state‑of‑the‑art cleanroom tools and execute the essential process steps. This model provides full hands-on engagement with our cutting‑edge facilities, allowing you to control every phase of your project.

Subcontracted Service
Alternatively, you can leverage our PTA technical team to implement the defined technological steps in close coordination with your project manager. This approach enables you to capitalize on our specialized expertise while dedicating your focus to the strategic aspects of your research and development.
