Abstract

The invention discloses a device for recovering photoresist in a coating machine pipeline. The device comprises a photoresist container, a photoresist pipeline, a photoresist extraction apparatus, a coating blade, and the coating machine pipeline, and also includes a photoresist recovery container. The photoresist recovery container is in connection with the photoresist extraction apparatus through a photoresist recovery pipeline, the photoresist recovery pipeline is provided with a filter and a flowmeter, the photoresist extraction apparatus is equipped with three ports, a first port is connected to the photoresist pipeline, a second port is connected to the coating machine pipeline, and a third port is connected to the photoresist recovery pipeline. According to the invention, the photoresist in the coating blade and the coating machine pipeline is fully and reasonably utilized in the regular maintenance phase of the coating machine.

Description

technical field [0001] The invention relates to the field of semiconductor manufacturing, in particular to a photoresist coating and recycling device in the semiconductor manufacturing process. Background technique [0002] In the panel manufacturing process, photoresist coating is a key process technology. The main equipment for this process is a coating machine. The photoresist extraction device is an auxiliary equipment of the coating machine. The photoresist in the container is extracted to the photoresist pipeline and then transferred to the coating machine pipeline, and finally a layer of photoresist is evenly coated on the glass substrate through the movement of the coating blade. Since the width of the coating blade is the same as that of the glass substrate, in order to ensure uniform coating, many coating machine pipes are arranged on the coating blade, and under normal circumstances, each pipe needs to be filled with photoresist. [0003] In order to improve the ...
