摘要： The present disclosure provides a thermo-mechanically reliable copper TSV and a technique to form such TSV during BEOL processing. The TSV constitutes an annular trench which extends through the semiconductor substrate. The substrate defines the inner and outer sidewalls of the trench, which sidewalls are separated by a distance within the range of 5 to 10 microns. A conductive path comprising copper or a copper alloy extends within said trench from an upper surface of said first dielectric layer through said substrate. The substrate thickness can be 60 microns or less. A dielectric layer having interconnect metallization conductively connected to the conductive path is formed directly over said annular trench.

摘要： A first metallic diffusion barrier layer is formed on a last level metal plate exposed in an opening of a passivation layer. Optionally, a metallic adhesion promotion layer is formed on the first metallic diffusion barrier layer. An elemental metal conductive layer is formed on the metallic adhesion promotion layer, which provides a highly conductive structure that distributes current uniformly due to the higher electrical conductivity of the material than the layers above or below. A stack of the second metallic diffusion barrier layer and a wetting promotion layer is formed, on which a C4 ball is bonded. The elemental metal conductive layer distributes the current uniformly within the underbump metallurgy structure, which induces a more uniform current distribution in the C4 ball and enhanced electromigration resistance of the C4 ball.

摘要： A 3D integrated circuit structure is provided. The 3D integrated circuit structure includes an interface wafer including a first wiring layer, a first active circuitry layer including active circuitry, and a wafer including active circuitry. The first active circuitry layer is bonded face down to the interface wafer, and the wafer is bonded face down to the first active circuitry layer. The first active circuitry layer is lower-cost than the wafer.
