Programmable Self-assembly for Heterogeneous Integration of Microsystems

Abstract
Self-assembly is the spontaneous and reversible organization of components into ordered structures, representing an alternative to the conventional manufacture of systems made of components from milli to nano scales. First commercial applications of self-assembly have appeared in recent years, for example in the fabrication of radio frequency identification tags. However, the full impact of this new approach towards hetero system integration will only be realized once self-assembly can be programmed on demand. This presentation gives an overview of several projects that aim at programmable self-assembly. A key concept is the “programmable surface” – an interface whose properties can be controlled with high spatial and temporal resolution. Several crucial topics are discussed: real time control of interfacial properties; optimization of binding site designs; and algorithms for the modeling and control of self-assembly. Promising novel manufacturing methods are emerging that combine the precision and reproducibility of semiconductor fabrication with the scalability and parallelism of stochastic self-assembly and with the specificity and programmability of biochemical processes.

Biography

Speaker: Jessica Meloy

Introduction: The time-resolved characterization of complex wall-bounded flow fields is difficult and unachievable with the current set of research tools. At the University of Florida the Interdisciplinary Microsystems Group (IMG) has teamed with FCAAP to develop the next generation of instrumentation grade sensors for aerospace applications. Specifically, microelectromechanical systems (MEMS) technology is being used to develop sensor systems for reliable direct time-resolved shear stress measurement and fill this instrumentation void. IMG has developed a robust miniaturized package for integration into flow control studies currently being conducted at both the Advanced Aero-Propulsion Laboratory at Florida State University and at IMG wind tunnel facilities at the University of Florida. The specific sensor system being utilized in these studies is capable of measuring shear stress values as low as 1mPa with a sensitivity of 1.7mV/V/Pa and at least 80dB rejection to cross sensitivities. In this seminar the sensor system’s circuitry and package development will be discussed.
