Abstract

The invention discloses a semiconductor material cleaning device, which comprises: a cleaning box capable of hierarchically cleaning a semiconductor material in the height direction, a vibrating plateis arranged at the bottom of the cleaning box, and the vibrating plate is elastically arranged at the bottom of the cleaning box; a liquid storage tank which is used for storing cleaning liquid, wherein the cleaning liquid is pumped into the cleaning tank through a pump body, so that the semiconductor material is flushed by layers in a circumferential array manner; a circulating material stirringbarrel which is in a thin-plate cylindrical shape, the top and the bottom of the circulating material stirring barrel are open, wherein a plurality of material stirring rods are arranged on the circumferential inner side wall of the circulating material stirring barrel; cleaning pipeline assemblies which are distributed on the inner side wall of the cleaning box in an annular array mode; a cleaning roller assembly which is located at the bottom of the cleaning box and conducts rolling cleaning on the semiconductor material; a driving part which can simultaneously control the circulating material stirring barrel body and the cleaning roller assembly to synchronously rotate; and a vibration assembly which generates periodic vibration on the vibration plate, wherein overturning and positionreplacement of the semiconductor material are realized by matching with a material stirring rod, and therefore, the semiconductor material can be flushed more cleanly and cleaned more thoroughly, andthe cleaning efficiency and effect are improved.

Description

technical field [0001] The invention relates to the field of cleaning devices, in particular to a cleaning device for semiconductor materials. Background technique [0002] In the current manufacturing process of semiconductor materials, various organic compounds, metal impurities and particles will adhere to the surface of semiconductor materials, and the cleanliness of the surface of semiconductor materials is one of the important factors affecting the reliability of semiconductor devices. If it is not cleaned, it will be greatly reduced. The performance and pass rate of semiconductor devices, so in the manufacturing process of semiconductor devices, 20% of the steps are cleaning of semiconductor materials, removing organic compounds, metal impurities and particles attached to the surface of semiconductor materials, and improving the quality of semiconductor devices. performance and pass rate. [0003] However, in the process of realizing the technical solution of the inv...
