Embodiment Construction

[0041] In order to make the above objects, features and beneficial effects of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0042] figure 1 It is a structural schematic diagram of the exposure process of the exposure machine in an embodiment of the present invention; figure 2 yes figure 1 The top view of the mask plate and substrate in ; image 3 yes figure 2 An exposure result of the film layer to be exposed on the middle substrate.

[0043] First refer to figure 1 As shown, the exposure machine needs to use the baffle plate 1 to shield the areas on the substrate 2 that do not need to be exposed during the exposure process.

[0044] The method for determining the position of the baffle 1 includes the following steps, which will be introduced respectively below.

[0045] First, combine figure 1 and figure 2 As shown, the film layer 20 to be exp...

Abstract

A method for determining the baffle position of an exposure machine. In the present invention, by changing the position of the baffle position confirmation figure, it is set near the common boundary of two exposure sub-regions, so that in the process of checking the baffle position confirmation figure once, it can Simultaneously check the boundaries of the two sub-exposure areas. Compared with the method of checking the boundary of one sub-exposure area each time, the method can improve the inspection efficiency, reduce the browsing amount of confirmation graphics, shorten the inspection time, and increase the production capacity.

Description

technical field [0001] The present invention relates to the technical field of exposure equipment, in particular to a method for determining the position of a baffle of an exposure machine. Background technique [0002] In recent years, with the rapid development of the information and communication field, the requirements for various types of display devices are increasing. Among them, the liquid crystal display panel (LCD) has gradually developed into a mainstream display device due to its lightness, thinness, small size, low power consumption, and low radiation. Taking the liquid crystal driving mode as TN (Twisted Nematic) as an example, the liquid crystal display panel generally includes: a color filter substrate, a thin film transistor substrate and a liquid crystal between them. Wherein, the color filter substrate mainly includes: a glass substrate, a black matrix layer located on the glass substrate, a color filter layer located on the glass substrate not covered by...
