    摘要： The present invention relates to an apparatus and method of manufacturing silicon seed rod in which two silicon seeds are joined into one long silicon seed rod by mechanical coupling. A mechanical seed coupler is a body in having an outer wall, an upper surface with an upper aperture, a lower surface with a lower aperture, and an inner wall surrounding an inner space. The mechanical seed couple can be of a shape including a cylinder shape, an elliptical tube shape, a rectangular tube shape and a square tube shape. Furthermore the mechanical seed coupler can be of unitary construction, made from one solid piece of material, or it can be composed of subparts.
