摘要

为了分析升华物组分对柱状隔垫物性能的影响机制

对目前量产通用的隔垫物材料A和含有升华物组分的隔垫物材料B进行了研究。通过FTIR

3D扫描显微镜

弹性测试和量产测试等方法对隔垫物材料的升华物成分、形貌、力学性能和量产稳定性进行了分析。实验结果表明

添加的升华物组分是一种熔沸点较低的丙烯酸酯单体

相同工艺条件下可以增大隔垫物的顶面面积约1.5m

同时减小其底面面积约1m。但是在大批量产的过程中

会在掩膜板上凝结升华物形成曲面薄膜

增加辅助隔垫物的尺寸和高度。添加的升华物组分可以提高隔垫物的抗压强度

同时可以对应高PPI TFT-LCD产品的开发需求

但是会使低温气泡等不良发生的概率变大。

Abstract

In order to analyze the influencing mechanism of sublimate components on performance of photo spacer

a comparative research between material A of mass production and material B contained sublimate components is studied. By method of FTIR

3D scanning microscope

elasticity test and mass production test

the sublimate components

profile

mechanical property and stability of mass production about photo spacer are analyzed. The experiment results show that the additive sublimate component is a kind of acrylate monomer which has lower melting and boiling point

it can increase about 1.5m of top CD at the same process condition. The acrylate monomer can also decrease about 1m of bottom CD

but it will form sublimate curved film on the mask during the process of mass production

and increase sub photo spacer size and height. The additive sublimate components can improve compressive strength of photo spacer and meet the requirement of high PPI TFT-LCD products

but it will increase the risk of cold bubble.
