Abstract The feasibility of low-ohmic FIB contacts to silicon with a localized silicidation was presented at ISTFA 2004 [1]. We have systematically explored options in contacting diffusions with FIB metal depositions directly. A demonstration of a 200nm x 200nm contact on source/drain diffusion level is given. The remaining article focuses on the properties of FIB deposited contacts on differently doped n-type Silicon. After the ion beam assisted platinum deposition a silicide was formed using a forming current in two configurations. The electrical properties of the contacts are compared to furnace anneal standards. Parameters of Schottky-barriers and thermal effects of the formation current are studied with numerical simulation. TEM images and material analysis of the low ohmic contacts show a Pt-silicide formed on a silicon surface with no visible defects. The findings indicate which process parameters need a more detailed investigation in order to establish values for a practical process.

Film Collapse

In order to clarify the dominant driving force of complex vapor film collapse behavior, numerical simulation is performed with three-dimensional fifteen-velocity lattice gas automata method. As the result, numerical result is qualitatively different from the experimental result. On the other hand, numerical simulation of vapor film collapse behavior is performed with three-dimensional fifteen-velocity lattice gas automata method including phase-change effect. As the result, numerical result is qualitatively similar to the experimental results. Comparison between the experimental result and the numerical result confirms that experimentally observed vapor film collapse behavior is dominated not by fluid motion but by phase change.

Abstract: The moisture flow and drying of porous media, such as concrete, is tackled through the Navier-Stokes equation, where the Navier-Stokes equation is considered as the link between the theory of fluid flow, Acoustic Emission (AE) experiments on cracking (sound propagation based on the wave equation) and Lattice Gas Automata, (LGA) being a numerical simulation of the Navier-Stokes equation. Early age cracking in the ITZ is induced by using the moisture flow as the only “load” that causes cracking due to drying shrinkage volume changes in Environmental Scanning Electron Microscopy (ESEM) tests. An attempt is made to link and compare experimental results conducted by means of AE and ESEM to the results of 2-D LGA numerical simulation. Lattice Gas Automata (FHP model) is used as a basis to generate a new model for drying of porous medium. Special emphasis in a model creation is given to the Interface Transition Zone (ITZ), between aggregate and cement paste, because of the early crack initiation in this highly porous and strength-weak zone.
