Abstract:
A low aspect ratio interconnect is provided and includes a metallization layer, a liner and a metallic interconnect. The metallization layer includes bottommost and uppermost surfaces. The uppermost surface has a maximum post-deposition height from the bottommost surface at first metallization layer portions. The metallization layer defines a trench at second metallization layer portions. The liner includes is disposed to line the trench and includes liner sidewalls that have terminal edges that extend to the maximum post-deposition height and lie coplanar with the uppermost surface at the first metallization layer portions. The metallic interconnect is disposed on the liner to fill a trench remainder and has an uppermost interconnect surface that extends to the maximum post-deposition height and lies coplanar with the uppermost surface at the first metallization layer portions.

Claim (Index 19):
A method of forming a device with multiple low aspect ratio interconnects, the method comprising:\n forming multiple lower interconnect layers with lower trenches, lower trench liners and lower metallic interconnects; depositing a cap on each of the multiple lower interconnect layers; disposing a metallization layer on an uppermost cap, the metallization layer comprising metallic interconnect material disposed over a liner deposited on metallization layer material defining a trench; polishing the metallic interconnect material to an upper portion of the liner and an uppermost surface of a metallic interconnect; and etching liner material at the upper portion of the liner and the metallic interconnect material at the uppermost surface of the metallic interconnect to an uppermost surface of the metallization layer.
