Patent ID: 10151045

Abstract:
A method for producing a crystal, according to the present invention, where the lower surface 4B of a seed crystal 4 which is rotatably arranged and made of silicon carbide is brought into contact with a solution 5 of silicon solvent containing carbon in a crucible 6 which is rotatably arranged and the seed crystal 4 is pulled up and a crystal of silicon carbide is grown from the solution 5 on the lower surface 4B of the seed crystal 4, comprising the steps of bringing the lower surface 4B of the seed crystal 4 into contact with the solution 5 in a contact step, rotating the seed crystal 4 in a seed crystal rotation step, rotating the crucible 6 in a crucible rotation step, and stopping rotation of the crucible 6, while the seed crystal 4 is rotated in the state in which the lower surface 4B of the seed crystal 4 is in contact with the solution 5, in a deceleration step.
