For several years, the two cleanrooms in Grenoble and Lyon, united within the Alliance Carat, have been leading a proactive policy of openness to industrialists, which has led to a rapid increase in the number of industrial partners. The aim of the project is to strengthen the equipment and know-how of the Carat cleanroom for a range of technological sectors associated with the fields of digital excellence, health and energy. On its complementary position to that of the technology clean room Leti, Carat aims, through the project, to increase its industrial partnerships in the Auvergne Rhône Alpes Region and to maintain a strong dynamic at the service of upstream and technological research and training.
