IMT Bucharest is a non-budgetary public research unit supervised by the Romanian Ministry of Education, Research and Innovation. The field of activity of IMT-Bucharest covers: micro and nano-fabrication technologies, microsystems including MOEMS and RF-MEMS. IMT coordinated or participated in 16 FP6 projects (IPs, STREPs, NoEs, RTNs) in the fiels of RF-MEMS, photonics, micro-nanotechnologies, microfluidics and is involved in 5 new FP7projects.

IMT will be involved in the design and characterization of optical system and RF antenna.

The laboratory of Micromachined microwave and millimeter wave circuits: has unique expertise in the field of Membrane supported millimeter wave circuits This topics started at IMT in 1996.The lab has coordinated one of the first European projects in the MEMS/Microwave topics, “Micromachined circuits for microwave and millimeter wave applications”- “MEMSWAVE” (FP4, 1998-2001) nominated for the Descartes Prize 2002. The team was involved in the FP6 European NoE in RF MEMS AMICOM, -“Advanced MEMS for RF and Millimeter Wave Communications”(2004-2007) developing Yagi-Uga and folded slot membrane supported antennas for mm wave circuits, millimetre wave receivers, components for millimetre wave identification systems and acoustic devices for GHz applications based on micromachining and nano-processing of GaN/Si. The lab is now coordinating the FP7 project MIMOMEMS “European Centre of Excellence in Microwave, Millimetre Wave and Optical Devices, based on Micro-Electro-Mechanical Systems for Advanced Communication Systems and Sensors” (project started in May 2008) and is participating at the FP7 STREP “MEMS 4 MMIC (coordinator IMST, Camp Linfort, Germany). The scientists from this group have published an important number of high quality papers in the topics of membrane supported millimeter wave circuits.


The laboratory has strong competence and expertise in the development of a new generation of circuits for millimetre wave communications based on the semiconductor micromachining and nanoprocessing materials. IMT will play a key role in the design, simulation and optimisation antennas, antennas array, and RF-switches for the millimeter wave range.

Commercial simulation tools (IE3D, Fidelity, Coventor), measurements facilities up to 110 GHz (VNA with wafer probe station, frequency synthesizer and spectrum analyzer), nanolithography equipments, AFM, mask manufacturing facilities are available and, consequently, IMT will contribute to mask manufacturing, measurement and characterization of developped circuits.


Resources: Commercial simulation tools (IE3D, Fidelity, Coventor), DC characterization Karl Suss EP4, Anritsu VNA and on wafer probe station (Karl Suss) up to 65 GHz (extension to 110 GHz in 2008 is financed from an EU project), VEGA 5136 LM SEM from TESCAN and ELPHY Plus  Nanolithography equipment from RAITH GmbH, access to AFM, mask manufacturing.
