目前LCD 製程主要是以狹縫式塗佈方式將感光染料塗佈於基板上再經由多重曝光、顯影、蝕刻的半導體技術進行彩色濾光片的製作；但是由於曝光、顯影、蝕刻的製程步驟所需的製程時間相當長，且在有限時間內增加產品製作數目必須縮短單一彩色濾光片的製程時間，因此，提出新式的彩色濾光片條紋式塗佈法。本計畫提出並使用的條紋式塗佈模式與以往使用的塗佈模式大不相同，主要是將彩色濾光片染料利用條紋式塗佈將其彩色顏料附著於黑色矩陣微小格子中(此一新穎的條紋式塗佈法正在申請專利中)，其中的條紋塗佈流體會藉由表面張力的拘束而不會溢流到不同色區的黑色矩陣中，而局限在同一色系的黑色矩陣方塊內，此一流體被拘束行為與流動不穩定之機制是非常有趣並值得探討的。此外，在條紋式塗佈實驗中，我們得到多孔式條紋塗佈的可塗佈的視窗是狹小的，同時會有許多的缺陷，如空氣滲入、塗佈條紋不連續、塗佈條紋粗細不一致。因此，針對多種造成塗佈不完全的流體現象進行不穩定的理論分析是必須且迫切的。本研究嘗試利用不同黑色矩陣的圖案設計與塗佈頭設計，進行新型的塗佈方法，研究塗佈液珠的成型與塗佈過程中液珠會隨著黑色矩陣寬度變化而調整的特性對彩色濾光片塗佈結果的影響程度，企圖找出塗佈液珠寬度變化對塗膜製程的影響因子，提升製程可靠度。 ; Nowadays the primary method of colorant photo-resist coating on color filter is a pigment dispersion method. It needs to repeat three times of slot coating, exposure, lithography, and etch. To reduce the colorant photo-resist usage and to shorten the stage of coating, a new method of color filter coating is addressed in this project: stripe coating. Stripe coating costs less colorant photoresist than pigment dispersion method, and it does not need three times of exposure, lithography, and etch. In our past study of stripe coating, the multi-aperture coating window was narrower than single one. And we had observed several defects like air containment and stripe breach. These phenomena let us be interested in the fluid instability of stripe coating. So this project will study the influences of flow rate, coating gap, slot gap and the manifold by using new stripe coating equipment. After this project, we hope we can optimize every operation factor to reduce the cost and raise the quality of color filter manufacturing. ; 研究期間 9708 ~ 9807
