Doing Research in Knowledge-based Societies
Franco Maloberti
University of Pavia – Italy

We live in knowledge societies, which are societies where the primary production resource is knowledge. The change of nature also involves changes in the institutions that create knowledge: Universities and Research centers. The increased relevance of knowledge values much more the institutions but, at the same time, creates new obligations and challenges. The relationship with advanced industries, especially those in the electronics area, becomes crucial, and the so-called R&D activity must be considered appropriately. The presentation discusses the above topics in a non-exhaustive manner just for providing elements of reflections to researchers and administrators.

CMOS-Compatible Piezoelectric MEMS for Fluidic and Acoustic Applications
Ulrich Schmid,1,* M. Schneider
Institute of Sensor and Actuator Systems, Austria

Electromechanical transducers based on the piezoelectric effect are continuously finding their way into micro-electromechanical systems (MEMS), typically in the form of thin films. Piezoelectric transducers feature a linear voltage response, no snap-in behaviour and can provide both attractive and repulsive forces. This removes inherent physical limitations present in the commonly used electrostatic transducer approach while maintaining beneficial properties such as low-power operation. Furthermore, piezoelectric materials can serve for both actuation and sensing purposes, thus enabling pure electrical excitation and read-out of the transducer element in combination with a compact design. Based on these outstanding features, piezoelectric transducers are operated most beneficially in a large variety of different application scenarios, ranging from resonators in liquid environment, advanced acoustic devices to sensors in harsh environments. In this talk, we will highlight latest results on the electrical, mechanical and piezoelectrical characterization of sputter-deposited aluminium nitride (AlN) including the impact of sputter parameters, film thickness and substrate preconditioning [1,2]. We will present the impact of doping of AlN with scandium, which leads to an increase of the moderate piezoelectric coefficient of AlN up to a factor of four. Finally, we will present some selected results of (Sc)AlN based acoustic devices ranging from droplet manipulation with a SAW structure to bistable PMUTs.

ImageProf. Ulrich Schmid started studies in physics and mathematics at the University of Kassel in 1992. In 1995, he spent 6 months at the Transport Group in the Physics Department, University of Nottingham, UK, to gain experience in wide band gap semiconductor device physics. He performed his diploma work at the research laboratories of the Daimler-Benz AG (now Daimler AG) on the electrical characterization of silicon carbide (6H-SiC) junction field effect transistors at high temperatures. During this time, he also investigated metal-oxide-semiconductor (MOSiC) based structures, such as gate controlled diodes, MOSFETs, and integrated circuits for harsh environment applications. He finished his studies in 1998 at the University of Frankfurt/Main, Germany. Prof. Schmid has authored or co-authored more than 400 peer-reviewed publications in journals and international conferences and holds more than 50 granted patent families. Furthermore, U. Schmid served twice as Chair for the SPIE Symposium “Microtechnologies” and as Programme Committee member for international conferences like IEEE Sensors, Eurosensors, Transducers, Micromechanics Workshop and the German Mikrosystemtechnik-Kongress

Cellular and Connectivity Circuits & Systems; the road ahead
Osama Shanaa
Associate Adjunct Professor, University of California, Berkeley
Sr. Director, RF design, MediaTek Inc.

Modern communication systems are rapidly increasing in complexity fueled by the high customer demand for data-rich media streaming over the airwaves. However, with limited and sometimes fragmented available spectrum for cellular communication, very complex modulation schemes with aggregated signal bandwidth are used to be able to “pack” such high data contents for wireless streaming. As a result, tremendous pressure is put on RFIC designers to deliver circuits that can handle such complex modulations and maintain the required high signal integrity while still be power efficient. Recently, the opening of new cellular spectrum in the mmWave bands offered a solution to the spectrum limitation but added an extra set of challenges to keep a reliable link while consuming a reasonable power that can fit in a slick phone design. On the connectivity side, we also see a similar trend in the newly launched WiFi7 802.11be, Extremely High Throughput (EHT), standard and the opening of the 6GHz band with 320MHz channel allocation. Similarly we have seen the rapid evolution of IoT and the likely transition from being the Internet-of-Things to becoming the Intelligence-of-Things. This talk walks the audience through the trends of where cellular and connectivity communication systems are heading and the impact this has on the circuit design and the corresponding implementation challenges. It also sheds some light on the considerations for high-efficiency and what areas of research are needed to enable and enhance such circuits moving forward.
