Methods of fabricating semiconductor devices having air gaps in dielectric layers
摘要：
Semiconductor devices, and methods of fabricating the same, include forming a trench between a plurality of patterns on a substrate to be adjacent to each other, forming a first sacrificial layer in the trench, forming a first porous insulation layer having a plurality of pores on the plurality of patterns and on the first sacrificial layer, and removing the first sacrificial layer through the plurality of pores of the first porous insulation layer to form a first air gap between the plurality of patterns and under the first porous insulation layer.
摘要（中）：

半导体器件及其制造方法包括在彼此相邻的衬底上的多个图案之间形成沟槽，在沟槽中形成第一牺牲层，形成具有多个孔的第一多孔绝缘层 所述多个图案和所述第一牺牲层上，并且通过所述第一多孔绝缘层的所述多个孔去除所述第一牺牲层，以在所述多个图案之间和所述第一多孔绝缘层下方形成第一气隙。
