Abstract
A method includes applying a first seed layer extending over a horizontal surface and via sidewalls of a dielectric material and exposed underlying contact metallization; removing at least some of the first seed layer from the contact metallization and the horizontal surface while leaving a sufficient amount of the first seed layer on the sidewalls as a catalyst for subsequent application of a third seed layer; sputtering a second seed layer over the contact metallization and the horizontal surface; using an electroless solution to react with the first seed layer and apply the third seed layer over the sidewalls; and electroplating an electroplated layer over the second and third seed layers.
