Abstract:
1. A structure, comprising: a multi-layer substrate comprising: a trench in said substrate passing through said metal layer and at least partially into said at least one other layer; a metal material partially lining said trench, said metal material being in contact with said metal layer; a dielectric material lining said metal material; a conductor filling said trench, said dielectric material separating said conductor from said metal layer, and said dielectric material additionally separating said conductor from said metal material lining said trench; a dielectric layer deposited on said metal layer; and a silicon-on-insulator (SOI) layer bonded on said dielectric layer, said trench passing through said dielectric layer and said SOI layer, and said metal material lining said trench being insulated from said SOI layer.
