A mos field effect transistor crystal pulling device

Abstract

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.

Description

technical field [0001] The invention relates to the technical field related to semiconductor production, in particular to a mos field effect transistor crystal pulling device. Background technique [0002] MOS scene effect transistor is a metal-oxide-semiconductor scene effect transistor. This device has two electrodes, one is metal, the other is external silicon (semiconductor material), and they are separated by a thin layer of silicon dioxide. Separation, among which semiconductor materials are indispensable, and crystal pulling refers to the process of arranging the molecules inside it when manufacturing crystal ingots. A balanced environment is conducive to the orderly arrangement of molecules in the ingot. [0003] When pulling the crystal, it mainly places the crystal pulling tube in the crystal pulling furnace, and provides a certain temperature through the crystal pulling furnace, so that a columnar crystal rod is formed in the crystal pulling tube, and is used for...
