20160035675 | LOW RESISTIVITY DAMASCENE INTERCONNECT - A damascene interconnect structure may be formed by forming a trench in an ILD. A diffusion barrier may be deposited on trench surfaces, followed by a first liner material. The first liner material may be removed from a bottom surface of the trench. A second liner material may be directionally deposited on the bottom. A conductive seed layer may be deposited on the first and second liner materials, and a conductive material may fill in the trench. A CMP process can remove excess material from the top of the structure. A damascene interconnect may include a dielectric having a trench, a first liner layer arranged on trench sidewalls, and a second liner layer arranged on a trench bottom. A conductive material may fill the trench. The first liner material may have low wettability and the second liner material may have high wettability with respect to the conductive material. | 02-04-2016 |
