The present disclosure is directed to an apparatus and method for growing a sapphire sheet via edge-defined film-fed growth (EFG) including an angled heat shield with respect to the a side surface of a die tip. The present disclosure is further directed to an sapphire sheets and batches of such sheets having features such as a particular maximum low spot thickness.

Sapphire sheets and apparatus and method for producing sapphire sheets with angled heat shields

Apparatus and method for growing a crystal from a melt of a growth material, wherein crystal growth occurs at a solid-liquid interface between the melt and the crystal, and a characteristic of the solid-liquid interface is determined by using a float atop the melt and a detector for detecting displacement of the float. The characteristic of the solid-liquid interface can be at least one of the following: position, velocity or acceleration of the solid-liquid interface.
