Abstract

An integrated circuit device includes a first interconnect layer, and a second interconnect layer above the first interconnect layer. The first interconnect layer includes (i) a first dielectric material, (ii) a recess within the first dielectric material, and (iii) a first interconnect feature within the recess. In an example, a top surface of the first interconnect feature is at least 1 nanometer (nm), or at least 3 nm, or at least 5 nm below a top surface of the first dielectric material. The second interconnect layer includes (i) a second dielectric material, and (ii) a second interconnect feature within the second dielectric material. In an example, the second interconnect feature is at least in part above, and conductively coupled to, the first interconnect feature. In an example, a bottom section of the second interconnect feature is within a top section of the recess.
