Abstract

The invention belongs to the technical field of semiconductors, and particularly relates to a polishing solution supply device for a quartz ring. An automatic polishing solution supply device for a quartz ring for a semiconductor comprises a polishing solution barrel, a polishing solution barrel cover, a stirring device, a polishing solution supply water pump, a pure water barrel and a stock solution barrel, the bottom of the pure water barrel is communicated with the polishing solution barrel through a pure water pump, and the bottom of the stock solution barrel is communicated with the polishing solution barrel through a polishing solution adjusting water pump. A polishing liquid return port is formed in the polishing liquid barrel cover and is connected with a polishing liquid outlet of the polishing machine through a pipeline; a tuning fork type densimeter and a temperature sensor are installed on the polishing solution barrel cover, a semiconductor refrigeration block is installed below the polishing solution barrel, the tuning fork type densimeter is connected with a pure water pump and a polishing solution adjusting water pump, and the temperature sensor is connected with the semiconductor refrigeration block. The polishing device can automatically adjust the concentration and temperature of the polishing solution, improves the polishing efficiency and precision, and is easy to operate and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of semiconductors, and in particular relates to a polishing liquid supply device for a quartz ring. Background technique [0002] With the prosperity of the semiconductor chip industry, the quartz ring for semiconductors is a key component in the entire process of semiconductor manufacturing. In particular, the technical parameters of the polished semiconductor quartz ring are extremely high. [0003] The polishing process of the quartz ring needs to place the quartz ring on the marble with polyurethane polishing skin, and the polishing liquid is transported to the polishing skin through the water pump for polishing. The traditional polishing liquid supply system is mainly a wave pump placed on the polishing surface. Stir in the liquid, and then the polishing liquid is transported through the water pump. In this method, due to the precipitation of the polishing liquid and the loss of the polishing liquid, t...
