The invention relates to the technical field related to
semiconductor production, and discloses a mos
field effect transistor crystal pulling device, which includes a support, a control device is fixedly installed in the middle of one side of the support, and an upper
heat pipe is fixedly installed on the top of the support , the side wall of the upper
heat pipe is fixedly installed with a wire
pipe, and the top of the wire
pipe is fixedly installed with the top of the support, and the bottom of the upper
heat pipe is threadedly connected with a lower heat
pipe. The wire tube of the present invention passes an
alternating current, so that the heat in the inner cavity of the heat pipe is increased through the wire tube, and the necessary temperature is provided for pulling the
crystal tube. At the same time, the alternating
magnetic field generated by the wire tube and the magnetic block repeatedly The magnetic block makes the pull
transistor move up and down in the inner cavity of the upper heat pipe, not only realizes the mixing of raw materials in the pull
transistor through continuous oscillation, but also causes the surface of the pull transistor to be in contact with the upper heat pipe at the same time through the up and down movement of the pull transistor. Contact with medium heat, and finally achieve the purpose of shaking the raw materials up and down and mixing them evenly.
