2 TALK #1 LIST OF CONTRIBUTED TALKS Title: Interfacing Brain and Machines: Challenges and Perspectives Speaker: Ángel Rodríguez-Vázquez Affiliation: Instituto de Microelectrónica de Sevilla, IMSE-CNM (CSIC/University of Seville), Abstract Interfacing brain and machines involve recording neural signals, extracting information from them and applying stimulations in closed loop. Applications are huge: from therapies for epilepsy and other kind of brain seizures to the control of prosthesis. Challenges are enormeous and truly multi-disciplinary: including, design of ultra low-noise microelectronic circuits with minimum power budget, energy scavenging, bio-compatibility, compressive sensing, etc. This talk identifies critical challenges and overviews proposed solutions. Discussions are illustrated with actual circuits tested in animals in collaboration between the Institute of Microelectronics of Seville, the University of Seville and the Institute of Bioengineering of the School of Medicine of the Universidad Miguel Hernandez.

4 TALK #2 Title: Industrial Integrated Circuit Design Techniques Speaker: Antonio J. Lopez-Martin Affiliation: Public University of NavarraCampus Arrosadia E Pamplona, Spain Abstract The design of industrial integrated circuits (IC) in today s advanced technologies is a challenging task that involves several relevant aspects often not considered by academic IC designers. Issues such as time-to-market, design reuse, design for test (DFT), design for manufacturing (DFM), yield, project negotiation and intellectual property management, are highly relevant and often not considered in academic projects. This talk will provide an introduction to the area of industrial integrated circuit (IC) design. It is mainly aimed academic researchers with little or no experience on industrial IC design that want to get involved eventually in the development of commercial IC design projects. Focus will be on practical aspects of industrial IC development, based on the experience of the author in research and development projects with various companies. A detailed case study of an ASIC developed by the author for contactless angular detection in automotive applications will serve to illustrate the different concepts treated in the talk.

6 TALK #3 Title: How to Make Your Integrated Sensor Smarter Speaker: Francisco Serra-Graells Affiliation: Integrated Circuits and Systems group, IMB-CNM(CSIC); Dept. Microelectronics and Electronic Systems, UAB Abstract More than Moore roadmaps predict a semiconductor market evolution towards new heterogeneous integrated systemon-chip products with built-in input and output transconductors. Unfortunately, it is not uncommon to find several examples of very promising sensors that could not fill the gap between sensor prototypes (devices) and final products (systems) due to the lack of suitable custom CMOS interfaces (circuits). This tutorial will introduce the design challenges associated with these read-out circuits, such as massive multi-channel A/D conversion, sensor biasing control loops, tuning capabilities against technology deviations, and calibration strategies, as well as some other practical aspects related with the powering and packaging of full smart sensors. The low-power and compact area CMOS read-out integrated circuit (ROIC) proposals presented in this tutorial are taken from real smart sensors examples developed at IMB-CNM(CSIC) for applications such as fast clinical analysis, toxic gas classification, portable chemical sensing, infrared and X-ray imaging and remote powered sensing nodes. Biography Francisco Serra-Graells (S'91-M'94) received the Enginyer de Telecomunicació degree and the Doctor Enginyer de Telecomunicació degree in 1993 and 2001, respectively, both from the Universitat Politècnica de Catalunya (UPC), Spain.

8 TALK #4 Title: Printed MicroElectronics: From Technology to Design, Rebuilding the Path Speakers: Eloi Ramon, Jordi Carrabina, Lluís Terés Affiliation: Universitat Autònoma de Barcelona, IMB-CNM, (CSIC) Abstract While silicon based technologies are evolving towards very advanced nanometric nodes ( 20ηm.), the emerging thinflexible-organic-large-area electronics (a.k.a. printed electronics, PE) based on flexible substrates and functional inks are starting again the history of microelectronics at technology and device levels trying to grow up to applications looking at the silicon path but far away from its costs and performances. Performance and size of PE devices are far away from Si devices; nevertheless there are a lot of new applications which have been enabled by those new technologies where the rigid silicon/pcb electronics doesn t have sense according to large area requirements (i.e. large area sensors), low cost (i.e. RFID tags or biosensors) or flexibility (i.e. wearables). In case that high performance is required the proposed solution is hybridization by using low temperature silicon-to-foil assembly processes while keeping the overall system flexibility. A successful and reliable process for printed devices is a key challenge for the concept of Printed Electronics. After reviewing the main printed-electronics technologies we will summarize the key characteristics, performances, cost factors and application domains for each one in order to keep clear these basic concepts around them. This presentation will also report the manufacturing and electrical characteristics of devices and circuits using printing deposition techniques and taking into account the yield, the usage of industrial relevant technologies and reporting about the manufacturing of electronic components such as resistors, conductive tracks, capacitors, inductors and transistors. Following the Si microelectronics experience we have proposed a methodology to go from early technology development stages up to physical design kit (PDK) and reusability-based design flows by means of PCells-based developments for basic technology structures, devices and std.-cells or even gate-array strategies. Such a methodology has been applied to three different technologies (ink-jet, gravure and evaporation based processes). 8
