发明名称 Semiconductor device having air gaps in multilayer wiring structure
摘要 A semiconductor device comprises a semiconductor substrate, and a multilayer wiring structure arranged on the semiconductor substrate, the multilayer wiring structure including a plurality of first electrically conductive lines, an insulating film covering the plurality of first electrically conductive lines, and a second electrically conductive line arranged on the insulating film so as to intersect the plurality of first electrically conductive lines, where the insulating film has gaps in at least some of a plurality of regions where the plurality of first electrically conductive lines and the second electrically conductive line intersect each other, and the width of the gap in a direction along the second electrically conductive line is not larger than the width of the first electrically conductive line.
