Optimised Piezoelectric PZT Thin Film Production on 8” Silicon Wafers for Micromechanical Applications

Kaden D., Gu-Stoppel S., Quenzer H.-J., Kaltenbacher D., Wagner B., Dudde R., Fraunhofer Inst. Silicon Technology, DE

Piezoelectric materials are of great interest for powerful actuation in MEMS devices. Due to its large electromechanical coupling coefficient Lead Zirconate Titanate (PZT) is one of the most favourable materials for realisation of fast and [...]

Combining Additive and Substractive techniques in the design and fabrication of Microfluidic devices

Levine L., ALine, Inc., US

Laminate construction of microfluidic devices offers a means to adopt both additive and subtractive manufacturing techniques for the development and manufacture of multiplexed fluidic devices that have porous membranes formed in-situ for applications in sample [...]

Angular Orientation-Specific Directed Self-assembly Enabling the Integration of Small Dies

Knuesel R.J., Bose S., Zheng W., Jacobs H.O., University of Minnesota, US

We report on recent progress in the directed self-assembly of discrete high performance semiconductor device components. Different from prior research, the goal is to enable the integration of ultra small dies (10-100 micrometer in size) [...]

Direct Patterning of Functional Materials via Atmospheric-Pressure Ion Deposition

Hamedinger T.E., Steindl T., Albering J., Rentenberger S., Saf R., Graz University of Technology, AU

Interest in thin films of functional organic materials has increased enormously in the past years because of various possible applications. Here we report an experimental setup for the processing of various organic materials into thin [...]

Defects and Fault Characterization in Quantum Cellular Automata

Baradaran Tahoori M., Momenzadeh M., Huang J., Lombardi F., Northeastern University, US

In this paper, a detailed simulation-based characterization of QCA defects and study of their effects at logic-level are presented. Different defect mechanisms for QCA active devices and interconnects are considered and the appropriate fault models [...]

A New Analytical Energy Relaxation Time Model for Device Simulation

Palankovski V., Kosina H., Hernandez A., Selberherr S., TU Vienna, AT

We present an empirical model for the electron energy relaxation time. It is based on Monte-Carlo simulation results and is applicable to all relevant diamond and zinc-blende structure semiconductors. The energy relaxation times are expressed [...]
