  • 在綠色產品意識抬頭下,TFT-LCD(Thin Film Transistor-Liquid Crystal Display)相關的零組件,也需要符合綠色產品要求。以本論文研究的彩色濾光片來說,其中BM(Black Matrix)製程上使用的材料重金屬鉻(Chromium,Cr)被替換後,使用的新材料黑色樹脂的光學密度表現就不如鉻金屬,且在加強光學密度改善時,卻發生液晶轉向不良,造成顯示畫面有殘影現象。
    本論文主要以改善黑色矩陣與彩色層重疊區域的斷差為重點,由研究黑色樹脂膜厚與光學密度的相對關係,然後探討黑色矩陣與彩色層重疊區域大小、研磨加工技術、高濃度黑色樹脂對斷差的影響。
    由實驗結果顯示,若BM要達到透光率小於萬分之一,則OD(Optical Density)值要大於4,在一般黑色樹脂矩陣膜厚約1.2μm下,彩色層與黑色矩陣重疊區控制在4μm內,可以得到斷差值小於0.5μm,同時彩色層中, Red光阻在彩色層與黑色矩陣重疊區4~6μm內,其斷差值皆能小於0.5μm。研磨加工對改善斷差約0.132μm,但當斷差較大時,研削量都集中在斷差的區域,而彩色層的研削量很小。
    高濃度樹脂膜厚只要約0.9μm就可達成光學密度(Optical Density)大於的要求,其膜厚比一般樹脂膜厚降低了約0.3μm,且彩色層與黑色矩陣重疊區控制在4μm內時,則可得到斷差值小於0.4μm。研磨對高濃度樹脂膜厚的研削量約0.091μm,但提高研磨力的條件下,卻無法有效增加研削量,並會造成過研磨的缺陷,且其面內的均一性有逐漸劣化的趨勢。

    The green product is remarkable in this century. Based on this reason, the related components of TFT-LCD (Thin Film Transistor- Liquid Crystal Display) need to achieve the requirement of the green product. About the Color filter in this study,
    Chromium is one of mental substance during Black Matrix producing. If Chromium is taken place by Black Resin under Optical Density (OD), the function of Black Resin could not work as well as Chromium. Even though increasing Optical Density, the Liquid Crystal could also be disoriented and the Monitor showed image residential.
    The aim of the study focused on the improvement Tuno-Dasan of Color Filter on Black Matrix (BM) of the Color Filter by studying the relationship between the thickness of resin Black Matrix and (OD), then, the effects on the difference between the overlap of color filter and BM, processing technology of polish, and Tuno-Dasan the thickness of higher OD BM resist were explored.
    The results of the experiment showed that if BM achieved less than 1/10000 transmittance and the value of OD was more than 4, the value of Tuno-Dasan would be 0.5μm by controlling the thickness of resin black matrix under1.2μ and color layer and the overlap of BM under 4μm, as well as Red photoresist under 4~6μm on the overlap of color layer and BM. Polish processing could improve Tuno-Dasan about 0.132μm. However, when Tuno-Dasan increased, polish volume all gathered on Tuno-Dasan area, but the polish volume on color layer was small.
    The thickness of higher OD BM resist which only needed 0.9μm would reach to requirement of OD (>4), and its thickness decreased 0.3μm which was less than general Resin’s; moreover, by controlling the overlap of color layer and BM under 4μm, the value of Tuno-Dasan would be less than 0.4μm. The polish volume of the thickness of higher OD BM resist was about 0.091μm, even though increasing polishing power; polish volume could not be effectively increased. Over polishing caused defect of pattern and homogeneity of the inside of pattern was getting worse in trend.
