Description

Portable silicon core sampling box Technical Field The utility model belongs to the technical field of silicon core transportation, and particularly relates to a portable silicon core sampling box. Background The silicon core is a component which plays an important role in the fields of polysilicon production, semiconductor manufacturing and the like, and is usually made of a silicon material, and the precision requirement is extremely high. The silicon core generally has specific size, shape and surface quality requirements to provide a uniform surface for crystalline silicon deposition or to be a critical component to the precise electrode and circuit structures, etc. of a semiconductor device. However, factors such as oxidation and bacteria have a significant impact on the accuracy of the silicon core. The oxidation can lead the size of the silicon core to be increased, the shape to be distorted, the surface roughness and the flatness to be poor, the electrical and mechanical properties to be changed, the precision to be destroyed, and the metabolic products generated by bacterial growth to corrode the silicon core to cause surface pollution and block the microstructure, thereby affecting the size, the shape and the surface precision of the silicon core and interfering the normal functions of the silicon core. Under the prior art conditions, a plurality of silicon core pieces are usually pumped down together and then stored in a warehouse. When the silicon core pieces are required to be taken in a workshop due to production or detection requirements, in order to maintain the low-oxygen sterile transfer environment required by the silicon core, the whole bag of silicon core pieces in a vacuum state has to be transferred all the time even if only one silicon core piece is required for single material taking. This way of transferring presents a series of significant problems. On one hand, the difficulty of material use management and storage management is greatly increased due to whole bag transfer, the use quantity and the residual inventory of the silicon controlled core pieces are difficult to accurately realize, and the situation of material waste or inventory shortage is easy to cause, and on the other hand, the risk of damage caused by unexpected factors such as collision, extrusion and the like exists in the whole bag silicon core pieces in the transferring process, so that the normal development of subsequent detection work and the accuracy of detection results are further affected. Therefore, the portable device capable of realizing convenient, safe and sterile sampling transfer of the silicon core is developed, and has important significance for solving the problems in the prior art and improving the use and management efficiency of the silicon core.
