Abstract

Embodiments described herein provide interconnect barrier layers and methods for forming such barriers. A dielectric body having a trench formed in a surface thereof is provided. A first layer is formed above the dielectric body within the trench. The first layer includes amorphous carbon. A second layer is formed above the first layer. The second layer includes a metal. The dielectric body, the first layer, and the second layer are heated to convert at least some of the amorphous carbon to graphene.
