A single-crystal silicon vertical single-rod square machine

Abstract

The invention discloses a single-crystal silicon vertical single-rod square cutting machine, which comprises a cutting chamber, a wiring chamber, a loading and unloading device, and an electrical chamber. The cutting chamber includes a cutting head for cutting a single silicon rod. The cutting chamber also includes a The silicon rod supporting seat supporting the lower end of the silicon rod and the silicon rod pressing mechanism for pressing and fixing the upper end of the silicon rod, the silicon rod pressing mechanism includes a pressing bracket, an extension rod fixed on the pressing bracket, and a The pressing seat on the extension rod is used for connecting with the silicon rod, and the extension rod is provided with a slot for the wire mesh of the cutting head to pass through. The invention achieves the high-efficiency processing effect of vertical cutting, no glue, no wire cutting, automatic alignment of crystal wires, automatic loading and unloading, simultaneous cutting on four sides, simple process, convenient operation, low processing cost, easy to realize automation, and conforms to User requirements for equipment.

Description

technical field [0001] The invention relates to the technical field of crystalline silicon cutting, in particular to a vertical single-rod squarer for monocrystalline silicon. Background technique [0002] The method of making single crystal silicon is usually to make polycrystalline silicon or amorphous silicon first, and then use Czochralski method or suspension zone melting method to grow rod-shaped single crystal silicon from the melt. When the molten elemental silicon is solidified, the silicon atoms are arranged in the diamond lattice to form many crystal nuclei. If these crystal nuclei grow into grains with the same crystal plane orientation, these grains combine in parallel to crystallize into single crystal silicon. Monocrystalline silicon, also known as silicon single crystal, is the most basic material in electronic information materials and photovoltaic industries, and belongs to the category of semiconductor materials. Monocrystalline silicon has penetrated int...
