Specification of a Common Framework for Characterizing Alignment

Abstract: Definition of a common framework for characterizing alignment of heterogeneous information. This report describes various approaches towards this goal and shows the relations between them. It also provides a description of the alignment sructure and process.

Effect of the tilt angle on antimony in silicon implanted wafers

Abstract: A dose of 5.0×1014 antimony (Sb+) ions cm−2 was implanted into silicon wafers at an energy of 70 keV, at different tilt angles (0°, 15°, 30°, 45°, and 60°). One set of samples was preamorphized with 160 keV germanium (Ge+) ions with a dose of 1×1015 cm−2. The second set consisted of implants into single crystal silicon. After implantation the samples were annealed at 700 °C for 30 s in a pure nitrogen ambient. Secondary ion mass spectroscopy was performed to evaluate the atomic profile and the retained dose as a function of the tilt angle before and after annealing. Rutherford backscattering spectroscopy and ion channeling measurements were performed to quantify the retained dose and the subtitutional fraction of antimony in the preamorphized and crystalline samples. Hall measurements were performed in order to calculate the proportion of the dopant which was electrically active. It was found that the substitutional fraction was a function of the tilt angle for all of the implanted samples. A correlation ...

Process and equipment for determining the alcoholic strength of a water/alcohol solution

Abstract: The process comprises the operations of: effecting heating of a predetermined quantity of water/alcohol solution until it partly or completely evaporates, detecting the change in its temperature over time during heating and evaporation of the said quantity of solution, and, determining the total energy necessary to bring about partial or complete evaporation of the said quantity of solution, or the time necessary for partial or complete evaporation, or the integral of that temperature over time during partial or complete evaporation, the value of each of these quantities being indicative of the alcohol concentration by volume in the water/alcohol solution.
