Book excerpt: The Czochralski (CZ) process for silicon crystal growth is a potential means for producing large power semiconductor and photovoltaic devices, but its development requires an improved understanding of the CZ process. This report presents models that describe heat transport and oxygen incorporation during CZ growth and that quantify the effects of operating parameters on crystal quality. It also describes a software package for calculating the axial profile of oxygen in the grown crystal.

Available in PDF, EPUB and Kindle. Book excerpt: 1 The content ofthis article is based on a German book version ) which appeared at the end of the year 1986. The author tried to incorporate - as far as possible - new important results published in the last year. But the literature in the field of "convection and inhomogeneities in crystal growth from the melt" has increased so much in the meantime that the reader and the collegues should make allowance for any incompleteness, also in the case that their important contributions have not been cited. This could for example hold for problems related to the Czochralski growth. But especially for this topic the reader may be refered to the forthcoming volume of this series, which contains special contributions on "Surface Tension Driven Flow in Crystal Growth Melts" by D. Schwabe and on "Convection in Czochralski Melts" by M. Mihelcic, W. Uelhoff, H. Wenzl and K. Wingerath. The preparation of this manuscript has been supported by several women whose help is gratefully acknowledged by the autor: Mrs. Gisela Neuner for the type writing, Mrs. Abigail Sanders, Mrs. Fiona Eels and especially Prof. Nancy Haegel for their help in questions of the English language and Mrs. Christa Weber for reading corrections. Also the good cooperation with the Springer Verlag, especially Mrs. Bohlen and with the managing editor of Crystals, Prof. H. C. Freyhardt, who critically read the manuscript, is acknowledged.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Czochralski crystal growth is a widely used technology for manufacturing semiconductor crystals. Currently, semiconductor manufacturers desire to increase the crystal diameter in order to minimize the unit cost per chip during wafer processing while also reducing dislocation density and micro defect level in order to fabricate circuits with decreasing line widths. However, the ability to meet these advanced manufacturing objectives is limited by the current process control architecture since it has not been explicitly designed to deal with important process complexities including the nonlinear and time varying dynamics and cross coupled physics. In order to design a better control system, a process model is developed to reflect the real equipment features of commercial scale Czochralski crystal growth furnaces and capture the fundamental process physics governed by heat and mass transport processes. The model is used to study the system dynamic characteristics and input-output relations in order to develop an improved control structure and control algorithm.

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.
