The integration of multifunctional microsystems is a leading trend in current micro- and nanoelectronics. Particularly, in the perspective of efficiently assembling huge amounts of very-small devices onto standalone structures, robotic pick-and-place in spite of its dexterity is not optimal due to seriality and handling issues. On the contrary, self-assembly methods are massively parallel and nonprehensile but needs to be directed. The convergence of the both approaches, as embodied by capillary flip-chip assembly, can therefore ideally address most of near-term electronic packaging needs. Capillary self-assembly will be the subject of my seminar. After a brief prelude on general
principles of self-assembly [1], I will define the capillary part-on-drop system that I studied in my PhD activity. I will then expose several related issues – e.g. experimental measurement of lateral capillary forces, finite-element and agent-based modeling of capillary self-assembly, selective dip-coating of patterned substrates, establishment of solder interconnects - that I addressed both theoretically and experimentally in my work, with the aim of bridging the gap between proof-of-concepts and industrial application of this promising packaging technique.

MM (’81) is PhD candidate at Katholieke Universiteit Leuven and IMEC (Leuven, BE), working on capillary self-assembly for microelectronic packaging. He got his B. S. and M. S. degrees in Electronic Engineering at the University of Pisa (Pisa, IT) in 2003 and 2005, respectively, specializing in the design and characterization of microelectromechanical resonators. During his current appointment, he was Visiting Scholar at the Electrical Engineering Dept. of the University of Washington (Seattle, USA), the Santa Fe Institute (Santa Fe, USA) and BEAMS Dept. of the Universite’ Libre de Bruxelles (Bruxelles, BE). His main interests span from complexity and music to sport and satire.
