    • A method for forming a multilayer includes a process for forming a first conductive layer on a substrate; a process for forming a first insulating layer on the first conductive layer; a process for forming a second conductive layer on the first insulating layer and patterning the deposited second conductive layer; a process for forming a second insulating layer over the substrate so as to cover the patterned the second conductive layer; a process for forming a third insulating layer on the second insulating layer, wherein an etching speed of the third insulating layer is faster than that of the second insulating layer; and a process for forming contact holes at once that expose at least a part of the first conductive layer to the first insulating layer, the second insulating layer and the third insulating layer.
    • 形成多层的方法包括在基板上形成第一导电层的工艺; 在第一导电层上形成第一绝缘层的工艺; 在第一绝缘层上形成第二导电层并图案化沉积的第二导电层的工艺; 在衬底上形成第二绝缘层以覆盖图案化的第二导电层的工艺; 用于在所述第二绝缘层上形成第三绝缘层的工艺,其中所述第三绝缘层的蚀刻速度比所述第二绝缘层的蚀刻速度快; 以及将第一导电层的至少一部分暴露于第一绝缘层,第二绝缘层和第三绝缘层的同时形成接触孔的工序。
