 The string ribbon method, also known as dendritic web or edge-supported pulling, has been used to grow semiconductor sheets including indium antimonide, gallium arsenide, germanium, and silicon.A seed crystal with the width and thickness matching the sheet to be grown is dipped into the top surface of the melt.Strings of a suitable material are fixed to the vertical edges of the seed and extend down through holes in the bottom of the crucible to a spool.
