Patent ID: 7982312

Claim:
A multilevel dual damascene structure comprising: a substrate having an upper surface, a lower surface and side surfaces connecting said top surface to said bottom surface; at least one single layer of photocurable dielectric material having a an upper surface, a lower surface and side surfaces connecting said top surface to said bottom surface, said lower surface of said layer of photocurable dielectric material being in continuous contact with said upper surface of said substrate; at least one line element recess extending along a horizontal plane at said upper surface of said photocurable dielectric material, said line element recess being filled with a conductive metal and having a metallic liner interfaced between said conductive metal and said layer of photocurable dielectric material, said conductive metal and said metallic liner being in coplanar relationship with said layer of photocurable dielectric material; at least one via element recess extending along a vertical plane between said upper surface of said photocurable dielectric material and said bottom surface of said photocurable dielectric material, or between said bottom surface of said photocurable dielectric and in contact with said line element material, said via element recess being filled with a conductive metal and having a metallic liner interfaced between said conductive metal and said layer of photocurable dielectric material, and when said via element recess extends to said top surface of said photocurable dielectric material, said conductive metal and said metallic liner, said via element is in coplanar relationship with said top surface of said photocurable dielectric material; a cap layer in continuous contact with said upper surface of said photocurable dielectric material.
