    • The present invention is related to a method for forming a storage node of a semiconductor device. The method includes the steps of: (a) forming a plurality of bit line patterns, each including a wire and a hard mask sequentially stacked on a surface of a substrate structure; (b) sequentially forming a first barrier layer and a first inter-layer insulation layer along a profile containing bit line patterns until filling spaces between the bit line patterns; (c) etching the first inter-layer insulation layer until a partial portion of the first inter-layer insulation layer remains on each space between the bit line patterns; (d) forming a second barrier layer on the first inter-layer insulation layer and the first barrier layer; and (e) etching the first and the second barrier layers and the remaining first inter-layer insulation layer to expose a surface of the substrate structure disposed between the bit line patterns.
    • 本发明涉及一种用于形成半导体器件的存储节点的方法。 该方法包括以下步骤:(a)形成多个位线图案,每个位线图案包括依次层叠在基板结构的表面上的导线和硬掩模; (b)沿着包含位线图形的轮廓依次形成第一阻挡层和第一层间绝缘层,直到填充位线图形之间的空间; (c)蚀刻第一层间绝缘层,直到第一层间绝缘层的部分部分保留在位线图案之间的每个空间上; (d)在第一层间绝缘层和第一阻挡层上形成第二阻挡层; 和(e)蚀刻第一和第二阻挡层和剩余的第一层间绝缘层以暴露位于位线图案之间的衬底结构的表面。
