  • Patent number: 10109586
    Abstract: Methods are devices are provided in which interconnection structures are formed using metal reflow techniques. For example, a method to fabricate a semiconductor device includes forming an opening in an ILD (inter-level dielectric) layer. The opening includes a via hole and a trench. A layer of diffusion barrier material is deposited to cover the ILD layer and to line the opening with the diffusion barrier material. A layer of first metallic material is deposited on the layer of diffusion barrier material to cover the ILD layer and to line the opening with the first metallic material. A reflow process is performed to allow the layer of first metallic material to reflow into the opening and at least partially fill the via hole with the first metallic material. A layer of second metallic material is deposited to at least partially fill a remaining portion of the opening in the ILD layer.
