Problems solved by technology

Trace contamination can also lead to device failure
The purpose of cleaning is to remove oily impurities on the surface, including organic and inorganic substances. Some of these impurities exist on the surface of the silicon wafer in the form of atoms or ions, and some exist in the form of thin films or particles. Due to the electrostatic effect, it is difficult to be cleaned by the cleaning machine, and the current cleaning machine is not highly automated, and it is necessary to manually place the basket and load the material

Abstract

The invention discloses a full-automatic silicon wafer cleaning device. The full-automatic silicon wafer cleaning device comprises a feeding mechanism, a conveying belt, an electrostatic removal channel, an auxiliary discharging mechanism, an ultrasonic cleaning mechanism and a drying channel. The full-automatic silicon wafer cleaning device is novel in structure, low in manufacturing cost and high in automation degree; and a silicon wafer sequentially passes through the feeding mechanism, the conveying belt, the electrostatic removal channel, the auxiliary discharging mechanism, the ultrasonic cleaning mechanism and the drying channel, and thus automatic feeding, automatic cleaning, automatic drying and discharging of silicon wafers are achieved, the operation is simple and convenient, the production time is greatly shortened, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of semiconductor silicon wafer processing, in particular to a fully automatic silicon wafer cleaning device. Background technique [0002] Silicon wafers must be strictly cleaned in the production of semiconductor devices. Trace contamination can also lead to device failure. The purpose of cleaning is to remove oily impurities on the surface, including organic and inorganic substances. Some of these impurities exist on the surface of the silicon wafer in the form of atoms or ions, and some exist in the form of thin films or particles. Due to the electrostatic effect, it is difficult to be cleaned by the washing machine, and the current washing machine is not highly automated, and it is necessary to manually place the basket and load the material. Contents of the invention [0003] The object of the present invention is to provide a fully automatic silicon wafer cleaning device to solve the problems raised in the a...
