Description
Technical field
The present invention relates to a kind of intermediate tone mask plate, belong to display panel preparing technical field.
Background technology
In TFT-LCD (Thin Film Transistor-LCD) processing procedure, PS (Post Spacer;Cylindrical spacer) be
One critical process of color filter (colored filter) layer.Exposure is the critical processes of PS processes, mask plate (Mask)
It is a basic tool of exposure.There are Main PS (main PS) and Sub simultaneously due to general on small size Panel (glass substrate)
Two kinds of highly different PS of PS (auxiliary PS), if making Main PS and Sub PS respectively using twice Mask exposures, can cause
The production capacities of PS processes reduces half, while will also result in the materials such as photoresist and developer solution doubles loss.Therefore, using together
Mask exposures make Main PS and Sub PS and are very important, and this Mask is commonly referred to as Halftone Mask (halftonings
Mask plate).
Halftone Mask technologies are, by reducing Sub PS aperture portion light transmittance, to be received with to reduce Sub PS
Light exposure so that the height of Sub PS after development is less than Main PS.For example in the thin gold of Sub PS aperture portion plating last layer
Belong to Cr(chromium), can so reduce the light transmittance of Sub PS opening portions, and cause the low regional exposure development of Sub PS light transmittances
Dimension of picture CD values afterwards reduce.As shown in figure 1, but be due to that existing Partial exposure machine is designed using special microscope group splicing,
Therefore, the splicing position 11 between adjacent two microscope group 1 can produce Mura (brightness irregularities), and commonly referred to as Lens Mura are (thoroughly
Mirror brightness irregularities).So, during exposure (as shown in Figure 1) using intermediate tone mask plate 2, the Sub in corresponding Lens Mura areas
PS height can be significantly lower than the Sub PS height in normal area, when being further combined into screen, cause Lens Mura areas brightness occur
It is different with other regions, so that producing Mura on TFT-LCD.
