 Czochralski growth using a floating shaper known as a "coracle" was done for some III-V semiconductors prior to the development of advanced control-systems for diameter control.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.
