Abstract:
1. A method comprising: providing a first substrate having a metal-dielectric pattern on a surface thereof, wherein the metal on the first substrate includes a concave upper surface, and wherein the dielectric on the first substrate includes a substantially uniform upper surface; providing a second substrate having a metal-dielectric pattern on a surface thereof; performing a process resulting in the metal being raised above the dielectric on the first substrate, wherein the performing of the process resulting in the metal being raised above the dielectric on the first substrate further causes the concave upper surface of the metal of the first substrate to have a substantially convex-dome shape; performing a process resulting in the metal being positioned substantially below the dielectric on the second substrate; bonding the metal raised above the dielectric on the first substrate to the metal positioned substantially below the dielectric on the second substrate at a temperature less than approximately 400 degrees Celsius, wherein the bonding forms a seam between the metal on the first substrate and the metal on the second substrate; and annealing after the bonding to substantially remove the seam.
