Abstract: An integrated circuit layout comprises a through silicon via (TSV) configured to couple positive operational voltage VDD (VDD TSV), a through silicon via (TSV) configured to couple operational signals (signal TSV), a plurality of through silicon vias (TSVs) configured to couple operational voltage VSS (VSS TSVs) around the VDD TSV and the signal TSV and one or more backside redistribution lines (RDLs) connecting the VSS TSVs together to form a web-like heat dissipating structure at least surrounding the VDD TSV and the signal TSV.

Abstract: A semiconductor device comprises a substrate, a through-silicon via (TSV) penetrating the substrate, a plurality of first interconnect structures, right above the TSV, configured for electrically coupling the TSV to a higher-level interconnect, a second interconnect structure traversing the TSV from the top and being configured for interconnect routing of an active device and a plurality of dummy metal patterns, right above the TSV, electrically isolated from the TSV, the first interconnect structures and the second interconnect structure.

Abstract: A stacked chip system is provided to comprise a first chip, a second chip, a first group of through silicon vias (TSVs) connecting the first chip and second chip and comprising at least one first VSS TSV, at least one first VDD TSV, a plurality of first signal TSVs and at least one first redundant TSV and a second group of through silicon vias (TSVs) connecting the first chip and second chip and comprising at least one second VSS TSV, at least one second VDD TSV, a plurality of second signal TSVs and at least one second redundant TSV, wherein all the first group of TSVs are coupled by a first selection circuitry configured to select the at least one first redundant TSV and bypass at least one of the rest of the first group of TSVs, and wherein the at least one first redundant TSV and the at least second redundant TSV are coupled by a second selection circuitry configured to allow one of them to replace the other.

Abstract: A method for fabricating a through-silicon via comprises the following steps. Provide a substrate. Form a through silicon hole in the substrate having a diameter of at least 1 ?m and a depth of at least 5 ?m. Perform a first chemical vapor deposition process with a first etching/deposition ratio to form a dielectric layer lining the bottom and sidewall of the through silicon hole and the top surface of the substrate. Perform a shape redressing treatment with a second etching/deposition ratio to change the profile of the dielectric layer. Repeat the first chemical vapor deposition process and the shape redressing treatment at least once until the thickness of the dielectric layer reaches to a predetermined value.
