Methods for producing rectangular seeds for ingot growth

A method of producing rectangular seeds for use in semiconductor or solar material manufacturing, the method comprising:

• connecting an adhesive layer to a top surface of a template, the template including a plurality of parallel slots;
• drawing alignment lines on the adhesive layer, the alignment lines aligned with at least some of the parallel slots;
• connecting quarter sections to the adhesive 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 with a wire web to separate the rectangular seed portions from the curved wing portions, wherein the sliced rectangular seed portions are rectangular seeds.
