RESEARCH FACILITIES

i3N integrates top facilities as required by high level research groups having as objective to be in forefront edge of research, technological development and innovation in the demanded areas of advanced micro/nano materials, nanotechnologies and nanosciences, and being responsible for boosting all known industry/applied research. This involves the use of high powerful computing tools; sophisticated labs for characterization and processing activities, such as clean rooms; use of  ophisticated equipment’s, in some cases highly expensive, such as SEM/FIB or ultra high vacuum units to process materials and devices; use of raw materials, special gases and components, among others. All this requires running funds, not only to maintain the existing facilities, but also to purchase the consumables and to pay the assistance to match existing tools for a specific process or characterization required along an experience or project. To this, we must add also some seed money for the development of novel ideas, as well as to participate on missions.

For the large infrastructures, the required running funds are substantially larger, such as the funds required to maintain the existing 400 m2 clean room facility, for the purpose of supporting research in the fields of microelectronics, electronic materials, nanotechnology, microfluidics, bioengineering, and devices and integrated circuits, requiring a low density particle environment.
