Abstract:
1. A semiconductor device, comprising: a first insulator structure; a first conductive feature partially within the first insulator structure, the first conductive feature having a portion at least partially protruding beyond a surface of the first insulator structure; a second insulator structure having a second conductive feature therein; a conformal intervening layer between the first and second insulator structures, wherein the first insulator structure, intervening layer, and second insulator structure are arranged in a stack, and wherein the conformal intervening layer conforms to the protruding portion of the conductive feature of the first insulator structure; and a conductive interconnect feature connecting the first conductive feature with the second conductive feature, the conductive interconnect feature passing through the conformal intervening layer and partially landing on the first conductive feature, wherein the unlanded portion of the conductive interconnect does not penetrate the conformal intervening layer.
