Methods for producing rectangular seeds for ingot growth

摘要

A method of producing rectangular seeds for use in semiconductor or solar material manufacturing includes connecting an adhesive layer to a top surface of a template, the template including a plurality of parallel slots, and drawing alignment lines on the adhesive layer, the alignment lines aligned with at least some of the parallel slots. The method also includes connecting quarter sections to the alignment layer such that an interface between a rectangular seed portion and a curved wing portion of each quarter section is aligned with at least one of the alignment lines drawn on the adhesive layer, and slicing each of the quarter sections to separate the rectangular seed portions from the curved wing portions.

1. A method of producing rectangular seeds for use in semiconductor or solar material manufacturing, the method comprising:
connecting an alignment layer to a top surface of a template, the template including a grid of horizontal and vertical slots; drawing alignment lines on the alignment layer to demarcate a plurality of nodes; connecting cylindrical rods to the alignment layer such that a center of each rod is aligned with a corresponding node; slicing through the rods and the alignment layer with a wire web to produce quarter sections each including a rectangular seed portion and a curved wing portion; and slicing each of the quarter sections with the wire web to separate the rectangular seed portions from the curved wing portions, wherein the sliced rectangular seed portions are rectangular seeds.
