Abstract
A device for growing a flat single crystal from a seed in a crystallization solution. A support element has a support face; a blocking element comprising a blocking face, positioned at a predefined distance from the support face to block the growth of the single crystal in a direction perpendicular to the support face; a seed protection member, configured to protect the seed during a crystallization solution treatment phase and to free a growth zone positioned between the support face and the blocking face during a rotation of the support element; the blocking element comprises a holding member that cooperates with the protection member, the holding member being movable between a first position where it holds the protection member against the support face during the treatment phase and a second position where the holding member is separated from the protection member and participates in the formation of the blocking face.
