No other area shows such a potential for disruption as digital platforms. B2C platforms, like Amazon and Uber, have radically changed the market situations within their industry. Until today, this change has mainly taken place in the B2C sector. Still, first platforms are already established in the B2B sector. Examples are Adamos in manufacturing and 365FarmNet in agriculture. With the entrance into the platform economy, companies are confronted with huge challenges. One question is whether a platform can be established in a certain industry due to its specific characteristics. Further questions are how a promising overall platform concept looks like, what relevant platform services are and who the essential actors on the platform are. In literature, there are different approaches for describing the benefits of a platform and designing a basic platform setup. Examples are the Platform Design Toolkit and Platform Value Canvas, which can be used for describing a platforms value proposition. Another example is the Platform Shell Model to describe the stakeholders of a platform. Still, those methods do not help companies to create a basis for decision-making for a platform strategy. In this paper we present a method for developing and evaluating concepts of a digital platform. Based on our project experience, we derived a thorough procedure complemented with adequate methods to do so. The starting point is the question of how a company should act regarding platforms in a certain industry. The goal is to develop platform concepts and to provide an initial evaluation. All relevant actors of an industry and their pains and gains should be considered. The platform concepts are based on the assumption that a platform can be described by its services and actors. The services should also be bundled into clusters with regard to their synergies in order to obtain consistent concepts. The validation shows that different platform concepts are promising depending on the ecosystem.

Uncertainty in key parameters within a chip and between different chips in the deep sub micron area plays a more and more important role. As a result, manufacturing process spreads need to be considered during the design process. Quantitative methodology is needed to ensure faultless functionality, despite existing process variations within given bounds, during product development. This book presents the technological, physical, and mathematical fundamentals for a design paradigm shift, from a deterministic process to a probability-orientated design process for microelectronic circuits. Readers will learn to evaluate the different sources of variations in the design flow in order to establish different design variants, while applying appropriate methods and tools to evaluate and optimize their design.

Lab-on-a-chip systems are increasingly applied in cell-based assays for toxicology and drug testing. In this paper, an on-chip integrated lensless microscopy module using a direct projection method for optical monitoring of the shadow images of adherent growing mammalian cells is presented. The biological cells are conserved and interfaced by a microfabricated cavity chip with a 1 mu m thick silicon nitride (Si(3)N(4)) substrate onto the surface of a 5 megapixel CMOS image sensor with 2.2 mu m pixel size. The optical resolution of the assembly is estimated by the contact/proximate printing theory from optical lithography. Further characterization is made by imaging microbeads in chips with the Si(3)N(4)-membrane as well as in cavity chips with membranes made from dry film resist (DFR, thickness 20, 40 and 60 mu m). The module represents a 3 x optical microscope for cell morphology imaging. The function is demonstrated by the growth monitoring of L929 cells cultured in cavity chips with Si(3)N(4) substrate for 2 days and by checking the colorimetric staining of cells with a compromised membrane.

It has been shown previously that peripheral nerve axons regenerate through microvias in silicon devices, A major challenge in the design of a biocompatible interface is to establish a reliable electrical and mechanical interconnection to signal-processing and transmission electronics which allows simultaneous multichannel recordings or stimulation of nerves, This paper describes the on-going work of developing a new generation of flexible and extremely light-weight electrode arrays with integrated cables. A process technology has been established to fabricate a multilayer device with micromachining methods, which overcomes the 'classical' separation of substrate and insulation layers, The micromachined electrodes exhibit promising mechanical stability and high insulation resistance.

This book is dedicated to Prof. Dr. Heinz Gerhuser on the occasion of his retirement both from the position of Executive Director of the fraunhoferinstitute for Integrated Circuits IIS and from the Endowed Chair of Information Technologies with a Focus on Communication Electronics (LIKE) at the Friedrich-Alexander-Universitt Erlangen-Nrnberg. Heinz Gerhuser's vision and entrepreneurial spirit have made the fraunhofer IIS one of the most successful and renowned German research institutions. He has been Director of the fraunhofer IIS since 1993, and under his leadership it has grown to become the largest of Germany's 60 fraunhoferinstitutes, a position it retains to this day, currently employing over 730 staff. Likely his most important scientific as well as application-related contribution was his pivotal role in the development of the mp3 format, which would later become a worldwide success. The contributions to this Festschrift were written by both fraunhofer IIS staff and external project team members in appreciation of Prof. Dr. Gerhuser's lifetime academic achievements and his inspiring leadership at the fraunhofer IIS. The papers reflect the broad spectrum of the institute's research activities and are grouped into sections on circuits, information systems, visual computing, and audio and multimedia. They provide academic and industrial researchers in fields like signal processing, sensor networks, microelectronics, and integrated circuits with an up-to-date overview of research results that have a huge potential for cutting-edge industrial applications.
