Abstract

The invention provides a reaction tank and wet process equipment. The reaction tank comprises a tank body, a cover plate and an air supply device, wherein the cover plate is arranged at a tank opening of the tank body; the cover plate is of a hollow structure, and an air cavity is formed in the cover plate; a plurality of air outlet holes are formed in the surface, facing the tank body, of the cover plate, and the air outlet holes communicate with the air cavity; and the air supply device communicates with the air cavity and used for conveying air into the air cavity.

Description

technical field [0001] The invention relates to the field of panel manufacturing, in particular to a reaction tank and wet process equipment. Background technique [0002] In the manufacturing process of the display screen, the specific film layer on the substrate is usually developed and etched in different reaction tanks with different functional chemicals such as developer solution and etching solution. During the wet etching process, the vapor formed with the volatilization of the chemical solution gradually adheres to the cover plate of the reaction tank to form water droplets. The water droplets continue to gather and drop to the substrate in the tank, resulting in the development or engraving of the film layer. Erosion is uneven. In addition, as the working hours prolong, a large amount of particle dirt will accumulate on the surface of the slot cover, and it will also fall onto the panel with water droplets, affecting the product yield. Contents of the invention ...
