Abstract
A semiconductor device includes a device layer with a semiconductor element, a first dielectric layer on the device layer, a first conductive line on the device layer and surrounded by the first dielectric layer, and a second dielectric layer on the first dielectric layer and around the first conductive line. The semiconductor includes a spacer disposed on the first conductive line and abutting a sidewall of the second dielectric layer, and a first conductive via disposed on the first conductive line and the spacer. The first conductive via includes a first segment positioned over the spacer and including a first width, and a second segment positioned between the first segment the first conductive line and including a second width. The first width is larger than the second width.
