MEMS Sensors and Actuators

Prof. Gabor Harsanyi
Budapest University of Technology and Economics, Department of Electronics Technology, Budapest, Hungary

This course will outline the basic technologies, structures and operation principles of various sensor and actuator (optoelectronic and passive) components applying MEMS (micro-electro-mechanical system) approaches. The device technologies gradually shifted from the hybrid integration applying beside semiconductors also ceramics, polymers, thick and thin films to single chip or stacked multichip MEMS structures that have small sizes, smaller consumption and can be integrated with smart functions. The large production scale and low cost of semiconductor based MEMS devices resulted in their widespread application not only in special fields like automotive and aerospace, but also in biomedical and consumer areas. The course will highlight the basic technology approaches, the possible mechanical elements that can be integrated with electrical circuit functions, gives a survey of examples from the practically realized structures, and their application possibilities are also discussed.


  1. Basic MEMS Technology Approaches: bulk micromachining and surface micromachining
  2. 3D MEMS Structures: trenches, membranes, bridges, cantilevers
  3. MEMS Sensor Examples: mechanical sensors, thermal sensors, chemical sensors, bosensors
  4. MEMS Actuator Examples: electrostatically land piezoelectrically driven types
  5. Application Examples: biomedical, automotive, consumer

Target audience

The course is designed for application designers and developers, MEMS developers as well as system development and manufacturing engineers to understand the operation principles and development trends of MEMS devices and to understand the direction for future requirements. Also newcomers are welcome since the course uses a description that can be understood easily.

Implications of New Semiconductor-Trends for IC-Packages

by Tanja Braun and Michael Töpper

Future electronic systems like autonomous systems using high-performance computing (HPC) and edge computing systems, sensor-integrated systems and bio-integrated devices will require more and more functions that cannot be managed by a single chip, even if advanced system on chip (SoC) concepts are used. In addition, a paradigm shift is taking place in many applications, in that data is progressively processed at a more localized level – from the cloud to the edge and down to the sensor node, thereby enabling meaningful information to be extracted, transmitted, stored or acted upon faster. 3D-stacking is also needed to realize smart sensor systems that aggregate a large amount of data and therefore have to be placed in close vicinity to the data processing, the data storage components and the transmission elements. Also, the increasingly higher costs for further node miniaturization in the IC manufacturing process will also promote the interconnection of chiplets. This means that intellectual property (IP) blocks made in different technology nodes will be combined on an interposer to reduce cost by increasing the production yield (smaller chips) and reuse across applications. In addition to the aforementioned approaches, optical intra-chip and intra-board communication need to be created in order to dramatically speed up communication and to significantly lower energy consumption

Therefore heterogeneous integration will appear at the chip package and organic substrate or panel level which will be discussed in this PDC.

Achieving High Reliability of Lead-Free Solder Joints – Materials Considerations

Ning-Cheng Lee
Vice President of Technology of Indium Corporation, USA

This course covers the detailed material considerations required for achieving high reliability for lead-free solder joints. The reliability discussed includes joint mechanical properties, development of type and extent of intermetallic compounds (IMC) under a variety of material combinations and aging conditions, and how those IMCs affect the reliability. The failure modes, thermal cycling reliability, and fragility of solder joints as a function of material combination, thermal history, and stress history will be addressed in details. The selection of novel alloys with reduced fragility will be presented. Crucial parameters for high reliability solder alloy for automotive industry will be presented. Electromigration, and tin whisker growth will also be discussed. The emphasis of this course is placed on the understanding of how the various factors contribute to the failure modes, and how the selection of proper solder alloys and surface finishes for achieving high reliability are key.
