    • In a method for forming a dual damascene wiring pattern, an etch stop film and an interlayer dielectric film comprising an SiOC:H group material are formed on a substrate having an electrical connection layer formed thereon. An anti-reflection layer is formed on the interlayer dielectric film. A primary opening is formed by etching the anti-reflection layer and the interlayer dielectric film to expose a surface of the etch stop film. A sacrificial film is formed comprising a low dielectric constant material in the primary opening and on the anti-reflection layer. A trench photoresist pattern having a width larger than that of the primary opening is formed on the sacrificial film after plasma-processing the sacrificial film. The sacrificial film, the anti-reflection layer and the interlayer dielectric film are sequentially etched using the trench photoresist pattern as an etch mask so as to form a secondary opening of a trench shape, and the trench photoresist pattern is removed, said secondary opening extending from an upper portion of the primary opening. The sacrificial film remaining is removed, the exposed etch stop film and anti-reflection layer are removed, the primary and secondary openings are filled with metal so as to be electrically coupled with the electrical connection layer. In this manner, damage to the etch stop layer is mitigated or eliminated during processing.
    • 在形成双镶嵌布线图案的方法中,在其上形成有电连接层的基板上形成蚀刻停止膜和包含SiOC:H基材料的层间电介质膜。 在层间电介质膜上形成防反射层。 通过蚀刻抗反射层和层间电介质膜形成初级开口以暴露蚀刻停止膜的表面。 在初级开口和抗反射层中形成包括低介电常数材料的牺牲膜。 在等离子体处理牺牲膜之后,在牺牲膜上形成具有大于初级开口的宽度的沟槽光致抗蚀剂图案。 使用沟槽光致抗蚀剂图案作为蚀刻掩模,依次蚀刻牺牲膜,抗反射层和层间电介质膜,以形成沟槽形状的次级开口,并移除沟槽光致抗蚀剂图案,所述次级开口延伸 从主开口的上部。 去除残留的牺牲膜,去除暴露的蚀刻停止膜和抗反射层,用金属填充初级和次级开口以与电连接层电耦合。 以这种方式,在处理期间减轻或消除对蚀刻停止层的损伤。

    • In order to avoid a faulty pattern resulting from a photoresist tail being formed due to a step difference of an upper hard mask layer when a dual hard mask layer is used, a planarization layer is formed following patterning of the upper hard mask layer. In this manner, a photoresist pattern is formed without the creation of a photoresist tail. Alternatively, a single hard mask layer and a planarization layer are substituted for the dual lower hard mask layer and an upper hard mask layer, respectively. In this manner, it is therefore possible to form a photoresist pattern without a photoresist tail being formed during photolithographic processes. In order to prevent formation of a facet, the planarization layer is thickly formed or, alternatively, the hard mask layer is etched using the photoresist pattern.
    • 为了避免当使用双硬掩模层时由于上部硬掩模层的阶差而形成的光致抗蚀剂尾部产生的故障图案,在上部硬掩模层的图案化之后形成平坦化层。 以这种方式,形成光致抗蚀剂图案而不产生光致抗蚀剂尾部。 或者,单个硬掩模层和平坦化层分别代替双下硬掩模层和上硬掩模层。 以这种方式,因此可以在光刻工艺期间形成光致抗蚀剂图案而不形成光致抗蚀剂尾部。 为了防止小面的形成,平坦化层被厚地形成,或者使用光致抗蚀剂图案蚀刻硬掩模层。
