    Abstract: A three dimensional integrated circuit (3D-IC) structure, method of manufacturing the same and design structure thereof are provided. The 3D-IC structure includes two chips having a dielectric layer, through substrate vias (TSVs) and pads formed on the dielectric layer. The dielectric layer is formed on a bottom surface of each chip. Pads are electrically connected to the corresponding TSVs. The chips are disposed vertically adjacent to each other. The bottom surface of a second chip faces the bottom surface of a first chip. The pads of the first chip are electrically connected to the pads of the second chip through a plurality of conductive bumps. The 3D-IC structure further includes a thermal via structure vertically disposed between the first chip and the second chip and laterally disposed between the corresponding conductive bumps. The thermal via structure has an upper portion and a lower portion.

    Abstract: A method including forming a plurality of dicing channels in a front side of a wafer; the plurality of dicing channels including a depth at least greater than a desired final thickness of the wafer, filling the plurality of dicing channels with a fill material and removing a portion of the wafer from a back side of the wafer until the desired final thickness is achieved, where a portion of the fill material within the plurality of dicing channel is exposed. The method further including depositing a metal layer on the back side of the wafer; removing the fill material from within the plurality of dicing channels to expose the metal layer at a bottom of the plurality of dicing channels, and removing a portion of the metal layer located at the bottom of the plurality of dicing channels.
