National Institute for Research and Development in Microtechnologies

The National Institute for Research and Development in Microtechnologies (IMT) is a non-budgetary public research unit supervised by the Romanian Ministry of Research and Innovation. The field of activity of IMT covers micro and nanofabrication technologies, microsystems including MOEMS, and RF MEMS. IMT has coordinated or participated in 3 H2020 (out of which a recent FETOPEN 2018-2021 in spin wave computing), 16 FP6 projects (IPs, STREPs, NoEs, RTNs) in the field of RFMEMS, photonics, micro-nanotechnologies, micro-fluidics, and was involved in 12 FP7 projects (IPs, STREPs, CSA) and 11 FP7- related projects (ENIAC JU, Cost, ERA-NET).

The Laboratory of Micromachined Microwave and Millimeter Wave Circuits has coordinated one of the first European projects on MEMS/Millimetre wave topics, MEMSWAVE (FP4, 1998-2001), nominated between the 10 finalists for the Descartes Prize in 2002. The laboratory is an EU centre of excellence for Advanced Communication Systems and Sensors based on MEMS technologies developed in multiple FP7 projects. The main topics of the Laboratory are focused on microwave millimeter wave circuits based on micromachining technologies of Si and GaAs and acoustic devices based on wide bandgap semiconductors.

In the last years, novel GHz operating SAW resonators based on micromachining and nanoprocessing of GaN/Si have been developed with broad applications in sensors and communication systems. Also graphene technologies have been developed in the lab. The laboratory currently is partner in one H2020-FET OPEN project and has finalized the coordination of a H2020 Marie Curie project. A high-performance nanolithography equipment and team are driving the novel work and state-of-the-art results of the laboratory. The scientists from this group have published an important number of high-quality papers in highly ranked journals.

The research topics include the development of a new generation of circuits devoted to mm-wave communication based on semiconductor (Si, GaAs, GaN) micromachining and nanoprocessing; acoustic devices (FBARs and SAWs) for applications in the GHz frequency range, based on micromachining and nanoprocessing of wide band gap semiconductors (GaN and AlN); sensors based on GaN/Si and AlN/Si acoustic devices, operating in the GHz frequency range; design and manufacturing of membrane-supported passive circuits elements; monolithic and hybrid integrated receiver front-ends based on Si and GaAs micromachining; RF MEMS and NEMS including microwave devices based on carbon nanotubes and graphene.
