The invention relates to the related technical field of
semiconductor production, and discloses a
crystal pulling device for a mos scene effect tube, wherein the device comprises a support, a control device is fixedly mounted in the middle of one side of the support, an upper
heat pipe is fixedly mounted at the top of the support, a line
pipe is fixedly mounted on the side wall of the upper
heat pipe, and the top end of the line
pipe and the top of the support are fixedly mounted; and the bottom of the upper
heat pipe is in threaded connection with a lower heat
pipe. The line pipe is electrified with
alternating current, so that heat in an inner cavity of the upper heat pipe is increased through the line pipe, and necessary temperature is provided for the
crystal pulling pipe; and meanwhile, a magnetic block enables the
crystal pulling pipe to move up and down in the inner cavity of the upper heat pipe through repeated attraction and repulsion between an alternating
magnetic field generated by the line pipe and the magnetic block; the raw materials in the crystal pulling pipe are mixed through continuous oscillation, the surface of the crystal pulling pipe is in contact with heat in the upper heat pipe at the same time through up-down movement of the crystal pulling pipe, and finally the purposes of mixing the raw materials through up-down oscillation and uniform heating are achieved.
