Abstract:
1. A semiconductor device, comprising: a lower dielectric film; an upper dielectric film formed in contact with the lower dielectric film; a first interconnecting line having a first lower part formed in the lower dielectric film and a first upper part formed in the upper dielectric film, the first upper part making contact with the first lower part; a second interconnecting line having a second lower part formed in the lower dielectric film and a second upper part formed in the upper dielectric film, the second upper part making contact with the second lower part; wherein the first lower part and the second upper part have a first constant width; the second lower part and the first upper part have a second constant width greater than the first constant width; and the first interconnecting line and the second interconnecting line have a first height and the first upper part, the second upper part, the first lower part, and the second lower part have a second height equal to half the first height.
