Title (EN) STRUCTURE AND MANUFACTURING METHOD FOR IGZO-TFT-BASED BOA LIQUID CRYSTAL PANEL
(FR) STRUCTURE ET PROCÉDÉ DE FABRICATION POUR UN PANNEAU À CRISTAUX LIQUIDES BOA À BASE DE TFT IGZO

Abstract:
(EN) A structure and manufacturing method for an IGZO-TFT-based BOA liquid crystal panel. The method comprises the following steps: 1) manufacturing a black matrix (2); 2) manufacturing a gate (4); 3) manufacturing a GI (5); 4) manufacturing source and drain electrodes (6); 5) manufacturing an IGZO (7); 6) manufacturing a PV (8); 7) manufacturing R/G/B (10); and 8) manufacturing an ITO (11). The manufacturing method proposes an IGZO-TFT BOA device using copper oxide as a black matrix (2) and having a co-plane structure, and effectively avoids the risk of an IGZO (7) being etched.
(FR) L'invention concerne une structure et un procédé de fabrication pour un panneau à cristaux liquides BOA à base de TFT IGZO. Le procédé comprend les étapes suivantes : 1) fabriquer une matrice noire (2) ; 2) fabriquer une grille (4) ; 3) fabriquer un GI (5) ; 4) fabriquer des électrodes de source et de drain (6) ; 5) fabriquer un IGZO (7) ; 6) fabriquer un PV (8) ; 7) fabriquer des R/V/B (10); et 8) fabriquer un ITO (11). Le procédé de fabrication propose un dispositif BOA TFT IGZO utilisant de l'oxyde de cuivre comme matrice noire (2) et ayant une structure coplanaire, et évite efficacement le risque de gravure d'un IGZO (7).
(ZH) 一种基于IGZO-TFT的BOA液晶面板的结构及制作方法,其中方法具有如下步骤:(1)制作黑色矩阵(2);(2)制作栅(4);(3)制作GI(5);(4)制作源漏极(6);(5)制作IGZO(7);(6)制作PV(8);(7)制作R/G/B(10);(8)制作ITO(11)。该制作方法提出了用氧化铜做黑色矩阵(2)的共平面结构的IGZO-TFT的BOA器件,有效地避免IGZO(7)被刻蚀的风险。
