Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] like figure 1 , 2 , 3, 4, and 5, a crystal pulling device includes a crystal pulling furnace 1, the crystal pulling furnace has a furnace chamber 11, and a crystal pulling tube 2 placed in the furnace chamber, the crystal pulling furnace There is a magnetic pole or an electric field on the furnace, and the furnace cavity is in the magnetic field or the electric field. It is characterized in that: it also includes an introduction, and the introduction includes a metal wire 3 arranged in the pulling transistor.

[0027] When this crystal pulling device is used, as in the prior art, the raw material powder is placed in the crystal pulling tube for crystal pulling, and the raw material is melted. Since a metal wire is arranged in the middle of the raw material, the arrangement of the crystal grain molecules can be promoted, and the crystal pulling speed can be achi...

Abstract

The invention relates to the technical field of crystal grain production equipment, in particular to a crystal pulling device which comprises a crystal pulling furnace, the crystal pulling furnace 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 device further comprises a primer. The primer comprises metal wires arranged in the crystal pulling tube; there are multiple metal wires, and the multiple metal wires are arranged in parallel; the length direction of the metal wires is parallel or perpendicular to the length direction of the crystal pulling tube; and the end part of the metal wires is arranged on the crystal pulling tube. The crystal pulling device can produce crystal bars which are more uniform in texture, better in crystal pulling effect and more excellent in quality.

Description

technical field [0001] The invention relates to the technical field of grain production equipment, in particular to crystal pulling equipment. 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 is placed in the crystal pul...
