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.

Comienzan los trabajos para incrementar la luminosidad del LHC

Comienzan los trabajos para incrementar la luminosidad del LHC El Gran Colisionador de Hadrones (LHC) entra oficialmente en una nueva fase. Hoy se ha celebrado una ceremonia en el laboratorio europeo de física de partículas (CERN) que marca el inicio del trabajo de ingeniería civil para el LHC de Alta Luminosidad (HL-LHC, por sus siglas en inglés): un nuevo hito en la historia del CERN. Al incrementar el número de colisiones en los grandes experimentos, esta gran actualización mejorará el rendimiento del LHC a partir de 2026, aumentando la probabilidad de descubrir nuevos fenómenos de la Física.

Recent publications

Novel impedimetric aptasensor for label-free detection of Escherichia coli O157:H7
Sergi Brosel-Oliu et al.; Sensors & Actuators: B. Chemical V. 255 P3 (2018) pp. 2988-2995. A novel impedance-based aptasensor for detection of E. coli O157:H7 is proposed. The limit of detection of the biosensor is around 102 cfu·mL-1 with a detection time of 30 minutes. The selectivity of the developed aptasensor is demonstrated in regard to other bacterial strains. Regeneration protocol for the aptasensor, to be employed more than once, has been developed


Resistive Switching with Self-Rectifying Tunability and Influence of the Oxide Layer Thickness in Ni/HfO2/n+-Si RRAM Devices
Alberto Rodríguez-Fernández et al.; IEEE Trans. Electron Dev. 64 (8) pp 3159-3166 (2017). The impact of the dielectric thickness, forming polarity, and current compliance on the self-rectifying current–voltage characteristics of Ni/HfO2/n+-Si RRAM devices has been investigated. In the case of 5-nm-thick oxide devices, a self-rectifying ratio of three orders of magnitude is observed after substrate injection forming (SIF) with current compliance below 500 μA. However, devices subjected to gate injection forming (GIF) do not exhibit such rectifying feature. This distinctive behavior for SIF is ascribed to the formation of a Schottky-like contact in between the Ni-based conducting filament and the semiconductor electrode.


Impedimetric label-free sensor for specific bacteria endotoxin detection by surface charge registration
Sergi Brosel-Oliu et al.; Electroquimica Acta, 2017, vol.243, pp.142-151 An impedimetric sensor based on a three dimensional electrode array modified with consecutive deposition of Con A-glycogen-Con A layers was used for label-free detection of bacterial endotoxin: lipopolysaccharide (LPS) from Escherichia coli. Presented biosensor is able to detect bacterial LPS in a very short detection time (20 min) with 2 μg mL−1 limit of detection, which is much lower than reported for other biosensors with Con A.


Compact Sampling Device Based on Wax Microfluidics
María Díaz-González et al.; Sensors and Actuators B 251 (2017) 93–98 This work reports on the design, fabrication and performance of a low-cost, self-contained sampling device based on a wax microfluidics technology. This sampler delivers leak- and contamination-free performance that ensures the integrity of the collected samples. Thanks to its small dimensions and low power requirements, this device is well suited for collecting samples on-board of small aerial or aquatic drones.


Thermal Phase Lag Heterodyne Infrared Imaging for Radio Frequency Integrated Circuits Performance Degradation Analysis
X. Perpiñà et al.; Appl. Phys. Lett., 101 (2) 094101 (2017). With thermal phase lag measurements, current paths are tracked in a Class A Radio Frequency (RF) power amplifier at 2 GHz. The phase lag maps evidence with a higher sensitivity than thermal amplitude measurements, an input-output loop due to a substrate capacitive coupling. This limits the amplifier’s performance, raising the power consumption in certain components. Other information relative to local power consumption and amplifier operation is also inferred. This approach allows the local non-invasive testing of integrated systems regardless of their operating frequency.


Highly Anisotropic Suspended Planar-Array Chips with Multidimensional Sub-Micrometric Biomolecular Patterns
J.P. Agusil et al.; Adv. Funct. Mater. 2017. The physical and chemical properties of silicon chips can be tuned to address the requirements of the research. The control of the physical anisotropy from fabrication allows obtaining chips with the desired aspect ratio, branching, faceting and size. Subsequent surface modification via wet chemistry or contact printing added two- and 3-dimensional chemical features on each microparticle. The combination of physical and chemical anisotropies provides the mean to create a myriad of customized microparticles.
