METHODS FOR FORMING COBALT-COPPER SELECTIVE FILL FOR AN INTERCONNECT |
摘要 |
Methods for processing a substrate include: (a) depositing a cobalt layer to a first thickness within a first plurality of features and a second plurality of features formed in a substrate, wherein each of the first plurality of features and each of the second plurality of features comprises an opening, and wherein a width of the openings of the first plurality of features is less than a width of the openings of the second plurality of features; and (b) heating the substrate to a first temperature to fill the first plurality of features with cobalt material while simultaneously depositing a fill material on the substrate to fill the second plurality of features. |
