Abstract

The invention relates to a seed crystal cleaning box, comprising a box body; the box body comprises two first side plates arranged opposite to each other and two second side plates arranged opposite to each other; the seed crystal cleaning box further comprises at least one spacer plate arranged in the box body; the two first side plates are respectively provided with spacer plate mounting holes, and the sizes of the spacer plate mounting holes are matched with the widths of the spacer plates; the spacer plate mounting holes are used for placing the spacer plates; the heights of the spacer plate mounting holes are greater than the thicknesses of the spacer plates; each spacer plate comprises a flat plate part and at least one bulge group arranged on the flat plate part, and each bulge group comprises a plurality of bulge parts. The seed crystal cleaning box is thorough in seed crystal cleaning, does not cause the phenomenon that the surface of the seed crystal is uneven, and increases the seed crystal cleaning effect.

Description

technical field [0001] The invention relates to the technical field of silicon single crystal equipment, in particular to a seed crystal cleaning box. Background technique [0002] Quasi-single crystal is a directional solidification technology that adopts single crystal seed crystal laying on the bottom. The preparation of the seed crystal is one of the key factors of the quasi-single crystal technology. When the seed crystal is laid in the crucible, the seed crystal is required to be pure and the side contact The surface is required to be flat, without obvious protrusions and pits, otherwise it is easy to cause defects in polycrystalline. The cleaning of the seed crystal is one of the key links in the preparation of the seed crystal, so the cleaning of the seed crystal has become the key content of the quasi-single crystal technology. [0003] After the seed crystal is cut and processed, there will be a large amount of impurity pollution on the surface, which needs to be ...
