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.

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.


The3D impedimetric sensors as a tool for monitoring bacterial response to antibiotics
S. Brosel-Oliu et al.; Lab.Chip, 2019, vol.19. pp. 1436 – 1447. The developed microbial sensor based on interdigitated electrode array (3D-IDEA) impedimetric transducer was employed in a biosensing platform especially designed to monitor the bacterial response to the antibiotic ampicillin. To facilitate immobilization of bacteria within the trenches and prevent their deposition on top of the barriers an important novelty is the use of polyIJN-isopropylmethacrylamide) p(NIPMAM) microgels working as antifouling agents, deposited on top of the barriers by microcontact printing.


High-resolution mapping of infraslow cortical brain activity enabled by graphene microtransistors
Eduard Masvidal-Codina et al.; Nature Materials volume 18, pages 280–288 (2019). The paper shows that arrays of graphene microtransistors are used to record infraslow cortical brain activity. The devices may be useful for monitoring of brain physiology.
