ABSTRACT:
A system for and method of growing a crystalline body of a selected material is described, whereby the body grown is of a selected cross-sectional shape. The system and method are used in accordance with known capillary die techniques and further includes observing opposite edge portions of the growing body, preferably just above the meniscus (of melt material from which the body is being pulled). The cross-sectional size of the growing crystalline body can be controlled by determining when horizontal shifts occur in the edge portions relative to each other as well as the same predetermined reference position.
