    • A method for forming a contact hole in a semiconductor device includes forming gate lines on a substrate, forming a bit line pattern by forming a bit line and a bit line hard mask in sequential order over the substrate, forming an inter-layer insulation layer having a multiple-layer structure including an etch stop layer over the substrate, forming a contact mask over the inter-layer insulation layer, performing a first etching process to etch a first portion of the inter-layer insulation layer above the etch stop layer, using the contact mask as an etch mask, and performing a second etching process to etch the etch stop layer, a second portion of the inter-layer insulation layer below the etch stop layer, and the bit line hard mask to form a contact hole exposing a portion of the bit line.
    • 一种用于在半导体器件中形成接触孔的方法包括在衬底上形成栅极线,通过在衬底上依次形成位线和位线硬掩模形成位线图案,形成层间绝缘层,该层间绝缘层具有 包括在衬底上的蚀刻停止层的多层结构,在层间绝缘层上形成接触掩模,执行第一蚀刻工艺以蚀刻蚀刻停止层上方的层间绝缘层的第一部分,使用 所述接触掩模作为蚀刻掩模,以及执行蚀刻所述蚀刻停止层的第二蚀刻工艺,所述蚀刻停止层下面的所述层间绝缘层的第二部分和所述位线硬掩模以形成暴露于 位线的一部分。
