This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work a technologically state-of-the-art growth furnace -- the FMF-module (Floating Zone Furnace with Rotating Magnetic Field) -- is under development for crystal growth experiments on the International Space Station. By using global simulations and the inverse modeling method, its optimal design and its performance could be obtained. By means of direct numerical simulations, the influence of solutal Marangoni convection on species transfer in a floating zone could be qualitatively explained. The instability mechanism of thermocapillary convection in a low Pr floating zone could be attributed to the interaction of buoyancy convection and surface flows. The direct numerical simulations were based on a full zone model.

Download or read book Adaptive Control of Interface by Temperature and Interface Profile Feedback in Transparent Multi-Zone Crystal Growth Furnace written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-06-30 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research is to control the dynamics of multizone programmable crystal growth furnaces. Due to the inevitable heat exchange among different heating zones and the transient nature of the process, the dynamics of multizone furnaces is time varying, distributed, and therefore complex in nature. Electrical power to heating zones and the translational speed of the ampoule are employed as inputs to control the dynamics. Structural properties of the crystal is the ultimate aim of this adaptive control system. These properties can be monitored in different ways. Following an order of complexity, these may include: (1) on line measurement of the material optical properties such as the refractive index of crystal; (2) on line x-ray imaging of the interface topology; (3) on line optical quantification of the interface profile such as the determination of concavity or convexity of the interface shape; and (4) on line temperature measurement at points closest to the material such as measurements of the ampoule's outside and inside surface temperatures. The research performed makes use of the temperature and optical measurements, specified in (3) and (4) as the outputs of furnace dynamics. However, if the instrumentation is available, the proposed control methodology can be extended to the measurements listed in (1) and (2). Batur, Celal Unspecified Center NCC3-150...
Book Synopsis Crystal Growth and Evaluation of Silicon for VLSI and ULSI by : Golla Eranna
Download or read book Crystal Growth and Evaluation of Silicon for VLSI and ULSI written by Golla Eranna and published by CRC Press. This book was released on 2014-12-08 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon, as a single-crystal semiconductor, has sparked a revolution in the field of electronics and touched nearly every field of science and technology. Though available abundantly as silica and in various other forms in nature, silicon is difficult to separate from its chemical compounds because of its reactivity. As a solid, silicon is chemically inert and stable, but growing it as a single crystal creates many technological challenges. Crystal Growth and Evaluation of Silicon for VLSI and ULSI is one of the first books to cover the systematic growth of silicon single crystals and the complete evaluation of silicon, from sand to useful wafers for device fabrication. Written for engineers and researchers working in semiconductor fabrication industries, this practical text: Describes different techniques used to grow silicon single crystals Explains how grown single-crystal ingots become a complete silicon wafer for integrated-circuit fabrication Reviews different methods to evaluate silicon wafers to determine suitability for device applications Analyzes silicon wafers in terms of resistivity and impurity concentration mapping Examines the effect of intentional and unintentional impurities Explores the defects found in regular silicon-crystal lattice Discusses silicon wafer preparation for VLSI and ULSI processing Crystal Growth and Evaluation of Silicon for VLSI and ULSI is an essential reference for different approaches to the selection of the basic silicon-containing compound, separation of silicon as metallurgical-grade pure silicon, subsequent purification, single-crystal growth, and defects and evaluation of the deviations within the grown crystals.
