    • The present invention fabricates a dual damascene structure. A passivation layer, a first dielectric layer, a second passivation layer, a second dielectric layer, a third passivation layer and a third dielectric layer are formed on the surface of the semiconductor wafer followed by etching the third dielectric layer to form a pattern of an upper trench of the dual damascene structure. Then the third passivation layer and the second dielectric layer are etched down to the surface of the second passivation layer so as to form a pattern of a via hole of the dual damascene structure. Thereafter, the third passivation layer and the second passivation layer not covered by the third dielectric layer and the second dielectric layer are removed. The third dielectric layer and the second passivation layer are used as hard masks to remove the second dielectric layer and the first dielectric layer until the surface of the first passivation layer. Finally, the second passivation layer and the first passivation layer not covered by the second dielectric layer and the first dielectric layer are removed to the surface of the conductive layer so completing the process of fabricating the dual damascene structure.
    • 本发明制造双镶嵌结构。 在半导体晶片的表面上形成钝化层,第一介电层,第二钝化层,第二介电层,第三钝化层和第三介电层,然后蚀刻第三介电层,形成图案 双层镶嵌结构的上沟槽。 然后,将第三钝化层和第二介电层向下蚀刻到第二钝化层的表面,以形成双镶嵌结构的通孔的图案。 此后,除去未被第三电介质层和第二电介质层覆盖的第三钝化层和第二钝化层。 第三介电层和第二钝化层用作硬掩模以去除第二介电层和第一介电层直到第一钝化层的表面。 最后,将第二钝化层和未被第二介电层和第一介电层覆盖的第一钝化层除去到导电层的表面,从而完成制造双镶嵌结构的工艺。

    • A method of forming a dual damascene structure. A substrate having a conductive layer thereon is provided. A passivation layer, a first dielectric layer, an etching stop layer, a second dielectric layer and cap layer serving as a base anti-reflection coating are sequentially formed over the substrate. The cap layer and the second dielectric layer are patterned to form a first opening that exposes a portion of the etching stop layer. A patterned negative photoresist layer having a second opening therein is formed above the cap layer. The cap layer exposed by the second opening and the second dielectric layer exposed by the first opening are removed. Thereafter, the second dielectric layer exposed by the second opening is removed to form a trench and the first dielectric layer exposed by the first opening is removed to form a via opening. The passivation layer exposed by via opening and then the negative photoresist layer is removed. A conformal barrier layer and a conductive layer are sequentially formed over the trench and the via opening with the conductive layer, completely filling the trench and the via opening.
    • 形成双镶嵌结构的方法。 提供其上具有导电层的基板。 在衬底上顺序形成钝化层,第一介电层,蚀刻停止层,第二电介质层和用作基底防反射涂层的覆盖层。 将盖层和第二介电层图案化以形成暴露蚀刻停止层的一部分的第一开口。 在其上方形成了具有第二开口的图案化的负性光致抗蚀剂层。 除去由第二开口暴露的盖层和由第一开口露出的第二介质层。 此后,除去由第二开口露出的第二电介质层以形成沟槽,并且去除由第一开口暴露的第一电介质层以形成通孔。 去除通过开口暴露的钝化层,然后去除负的光致抗蚀剂层。 在沟槽和通孔开口上依次形成保形阻挡层和导电层,导电层完全填充沟槽和通孔。
