Welcome to the IMB-CNM


Welcome to the web page of the Barcelona Microelectronics Institute of the National Microelectronics Centre-CSIC.

Micro/Nano electronics, Photonics and Smart Systems have been identified by the European Commission as a fundamental part of the KETS-Key Enabling Technologies, which are the basis for the improvement of the innovation capability of the European industry. These technologies have a high economic potential and the capability to contribute to solve the current societal challenges.

Electronic systems are part of our lives for several decades now. The evolution of microelectronics has enabled its introduction as an essential part of multiple products that can benefit any sector of the economy, by including properties such as a higher product intelligence or more sustainability.

The IMB-CNM aims to contribute to these goals with a high level set of researchers and facilities, unique in the South of Europe. Not only we can offer our know-how to collaborate with you on designing and fabricating new micro and nanoelectronics components, circuits and systems, but also we can provide you education and training at the different stages of your scientific or engineering career. IMB-CNM is a research centre belonging to CSIC, placed in Barcelona and, more specifically being part of the Campus of Excellence of the Universitat Autònoma de Barcelona (UAB), that is a cluster of scientific activity that may perfectly fit with your needs.

We thank you for visiting the web site of our institute and we hope that the R&D activities that we are doing can be of your interest. Please feel free to contact us for any collaboration or visit in which you may be thinking of.

Recent publications

Impedimetric transducers based on interdigitated electrode arrays for bacterial detection
S.Brosel-Oliu et al.; A review, Anal.Chim.Acta, 2019, vol.1088, pp. 1-19. This review is focused on publications dealing with interdigitated electrodes as a transducer unit and different bacteria detection systems using these devices. The first part of the review deals with the impedance technique principles, paying special attention to the use of interdigitated electrodes, while the main part of this work is focused on applications ranging from bacterial growth monitoring to label-free specific bacteria detection.


Power module electronics in HEV/EV applications: New trends in wide ban-dgap semiconductor technologies and design aspects
A. Matallana et al.; Renewable and Sustainable Energy Reviews, vol. 113, October 2019. This paper presents an in-deep review of the state of the art concerning power modules, identifying the electrical requirements for the modules and the power conversion topologies that will best suit future HEV/EV drives. Current wide band-gap (WBG) technologies such as SiC and GaN, are reviewed and, after a market analysis, the most suitable power semiconductor devices are highlighted. Among them, it can be concluded that JBS diodes and MOSFETs are the most adequate for this application, because they can substitute traditional Si FRD diodes and Si IGBTs, providing lower power losses and higher operation temperatures. The migration from Si IGBTs to the aforementioned technologies would be simpler than expected, as the same firing circuitry (with minor modifications) can be reused. The paper, also focuses on practical design aspects of the module, such as optimum WBG die parallelization, placement and ceramic substrate routing. This work has been developed in a collaboration between the Teknologia Elektronikoa Saila - Bilboko Ingenieritza Goi Eskola Teknikoa - UPV/EHU and the Power Devices and Systems Group from IMB-CNM(CSIC).


Growth Monitoring With Submonolayer Sensitivity Via Real-Time Thermal-Conductance Measurements
P. Ferrando-Villalba et al.; Phys. Rev. Applied 12, 014007. Growth monitoring during the early stages of vapor deposition is of prime importance to understand the growth process, the microstructure, and thus the overall layer properties. We demonstrate that phonons can be used as an extremely sensitive probe to monitor the real-time evolution of film microstructure during growth. For that purpose, a silicon nitride membrane-based sensor is fabricated to measure the in-plane thermal conductivity of thin film samples. Operating with the 3ω-Völklein method at low frequencies, the sensor shows an exceptional resolution down to Δ(κ⋅t)=0.065W/mKnm, enabling accurate measurements even in poor conductive samples.


Electric Field Gradients and Bipolar Electrochemistry effects on Neural Growth: A finite element study on immersed electroactive conducting electrode materials
Ll. Abad et al.; Electrochimica Acta. Implantable electrodes act with direct electrical contact although recent work has shown that electrostimulation is also possible through non-contact wireless settings, through the generation of dipoles at the borders of the material by bipolar electrochemistry. Finite element studies shown here with the same configuration that the experimental processes described, evidence voltage profiles in qualitative agreement with known bipolar effects, although with a clear difference between intercalation materials and metals. These observations may explain the differences in neural cell growth observed for various substrate material.


Mimicking the Spike-Timing dependent plasticity in HfO2-based memristors at multiple times scales
M. Maestro-Izquierdo et al.; Microelectronic Engineering 215 (2019) 111014. TiN/Ti/HfO2/W memristors have been investigated to mimic the spike-time dependent plasticity (STDP) of biological synapses at multiple time scales. For this purpose, a smart software tool has been implemented to control the instrumentation and to perform a dedicated ultra-fast pulsed characterization. Different time scales, from tens of milliseconds to hundreds of nanoseconds, have been explored to emulate the STDP learning rule in electronic synapses. The impact of such times on the synaptic weight potentiation and depression characteristics has also been discussed.


Microfluidic Modules with Integrated Solid-State Sensors for Reconfigurable Miniaturized Analysis Systems
Pablo Giménez-Gómez et al.; ACS Omega, 2019, 4 (4), pp 6192–6198. Modular microfluidic systems based on a new magnetic clamping approach, which enables both interconnection of microfluidic modules and reversible integration of solid-state sensors, is presented in this work. The system layout allows the easy assessment of the system fluidic performance by using optically transparent and low cost polymeric materials.
