A crystal pulling device for the preparation of heating electronic components

Abstract

The invention relates to the technical field of chip production, and discloses a crystal pulling device for preparing heating electronic components. In the compressed state, when the crystal nucleus is in contact with the molten silicon material in the molten state, if the temperature of the molten silicon material is too high at this time, the crystal nucleus in contact with the molten silicon material is subject to a higher temperature than its own. The melting point begins to melt, so that the total length of the crystal nucleus is reduced. At this time, the compression spring II is in a compressed state, and the crystal nucleus is pushed out from the inside of the fixed sleeve to ensure that the bottom of the crystal nucleus can always be kept in contact with the stroke rod. The bottom is in contact with each other, so that the extension length of the crystal nucleus from the inside of the fixed sleeve remains unchanged, which avoids the problem that the crystal nucleus is melted and the length is shortened due to the high temperature of the molten silicon material in the traditional crystal pulling equipment. The stability of the device when working.

Description

technical field [0001] The invention relates to the technical field of chip production, in particular to a crystal pulling device for preparing heating electronic components. Background technique [0002] Chip is currently the most difficult product to produce, and is known as the pearl of modern industry. An important step in the production of chips is the production of silicon ingots. The production quality of silicon ingots directly affects the final quality of chips. In the production of ingots, a crystal pulling device is required to extract high-purity silicon crystals from the molten silicon material by using the principle of crystallization. The traditional crystal pulling device consists of a furnace, a pulling device and a lifting device, and has a simple structure. It has the advantages of convenient use, low cost and the like, and is currently the most widely used crystal pulling device. [0003] Although the current crystal pulling device has many advantages, t...
