Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] Such as Figure 1-8 As shown, a pull transistor with metal wires includes a pull transistor body 1 , the pull transistor body has a side wall, and the feature is: the metal wire 2 is inside the side wall.

[0030] When the crystal pulling tube is used, as in the prior art, the raw material powder is placed in the crystal pulling tube and placed in the furnace chamber of the crystal pulling furnace for crystal pulling, and the furnace chamber is in an environment with a magnetic field and an electric field , the raw material is melted, because the metal wire is arranged in the middle of the raw material, it can promote the arrangement of the crystal grain molecules, and achieve the effect of fast crystal pulling speed. The metal wire is also beneficial to wake up more raw material molecules to rearrange, so as to achieve The purpose of better effect can achieve ...

Abstract

The invention relates to the technical field of crystal grain production consumables, in particular to a crystal pulling tube with metal wires and a crystal pulling furnace. The crystal pulling tube with the metal wire comprises a crystal pulling tube body, the crystal pulling tube body is provided with a side wall, and the metal wire is arranged in the side wall; the number of the metal wires is multiple, and the multiple metal wires are arranged in parallel. The length direction of the metal wires is parallel to or perpendicular to the length direction of the crystal pulling tube. The crystal pulling furnace comprises a crystal pulling furnace body, the crystal pulling furnace body is provided with a furnace chamber and a crystal pulling tube placed in the furnace chamber, the crystal pulling furnace is provided with a magnetic pole or an electric field, the furnace chamber is located in the magnetic field or the electric field, and the crystal pulling tube is the crystal pulling tube with the technical characteristics. The crystal pulling tube and the crystal pulling furnace have the advantages that the produced crystal bars are more uniform in texture, the crystal pulling effect is better, and the quality is more excellent.

Description

technical field [0001] The invention relates to the technical field of grain production consumables, in particular to a crystal pulling tube and a crystal pulling furnace. Background technique [0002] Grain is an important material that needs to be used in the production process of semiconductor refrigeration parts. It is cut from crystal rods. The crystal grains (crystal rods) are composed of neatly arranged molecules. The crystal rods are In the crystal pulling device, the crystal pulling device includes a crystal pulling furnace, the crystal pulling furnace has a furnace cavity, and a crystal pulling tube placed in the furnace cavity, and the crystal pulling furnace has a magnetic pole or electric field, the furnace cavity is in the magnetic field or electric field, when pulling the crystal, first place the powdery raw material (semiconductor raw material) in the crystal pulling tube, the pulling crystal tube is placed in the crystal pulling furnace, and the raw material...
