    • A method for forming contact plugs of a semiconductor device includes a step of forming a conductive layer on an insulating layer filling up a contact hole. The method further comprises a step of planarization-etching an upper surface of the insulating layer as well as the contact plugs, after formation of the contact plugs by etching the conductive layer using an etch-back or a CMP process until at least the upper surface of the insulating layer is exposed. Alternatively, the conductive and insulating layers are simultaneously planarization-etched using a CMP process once to form the contact plugs and planarize the upper surface of the insulating layer. With this method, a bridge between interconnections which can be generated due to a scratch of the upper surface of the insulating layer can be prevented by planarization-etching the conductive layer after filling up a contact hole with the conductive layer. Also, since the insulating layer includes a lower insulating layer and an upper insulating layer having a relatively high hardness to the lower insulating layer, high-step and low-step regions of the insulating layer formed along topology of a gate electrode or a metal interconnection are efficiently planarized. As a result, a thickness of the insulating layer can be considerably reduced.
    • 用于形成半导体器件的接触插塞的方法包括在填充接触孔的绝缘层上形成导电层的步骤。 该方法还包括在通过使用回蚀刻或CMP工艺蚀刻导电层形成接触插塞之后,平坦化 - 蚀刻绝缘层的上表面以及接触插塞的步骤,直到至少上表面 的绝缘层露出。 或者,使用CMP处理同时对导电绝缘层进行平面蚀刻,以形成接触插塞并平坦化绝缘层的上表面。 利用该方法,可以通过在与导电层填充接触孔之后对导电层进行平坦化蚀刻来防止由于绝缘层的上表面的划痕而产生的互连之间的桥。 此外,由于绝缘层包括下绝缘层和对下绝缘层具有相对较高硬度的上绝缘层,所以沿着栅电极或金属互连的拓扑形成绝缘层的高阶段和低阶区 有效地平坦化。 结果,绝缘层的厚度可以大大降低。
