Abstract
A semiconductor device is provided. The semiconductor device includes a semiconductor substrate and a first conductive feature over the semiconductor substrate. The semiconductor device also includes a first dielectric layer over the semiconductor substrate and surrounding the first conductive feature. The semiconductor device further includes a second conductive feature over the first conductive feature. A bottom surface of the second conductive feature is between a top surface of the first conductive feature and a bottom surface of the first conductive feature. In addition, the semiconductor device includes a second dielectric layer over the first dielectric layer and surrounding the second conductive feature. The semiconductor device also includes an etch stop layer between the first dielectric layer and the second dielectric layer. A top surface of the etch stop layer is between the top surface and the bottom surface of the first conductive feature.
