Dynamics of Semiconductor ``Web'' Growth

Abstract

The dynamics of ``web'' growth have been investigated, with particular emphasis on the meniscus. The meniscus deflections have been expressed as a function of surface tension, and pulling force. An effort is being made to describe the parameters which influence surface tension, and its reflection on the process of web growth, and the properties of the material. The degree of supercooling, crucible design, and the control of thermal gradients have profound effects on the quality of the crystal and its physical dimensions.
