摘要
Abstract
In 4-mask manufacturing process of the thin film transistor (TFT) liquid crystal display (LCD), multi-layer etch is a very critical process, because metal remain defect would happen after multi-layer etch, which will influence on the next insulator layer deposition, and induce layer broken.Conventional method for eliminating metal remain is to adjust multilayer etch process, but there is no fundamental improvement In this paper, the influence of data line etch time on metal remain after multi-layer etch has been researched, and it is found that metal remain could be fundamentally eliminated by adjusting data line etch time, and also could keep data line width in control.关键词
