  • Publication number: 20240128216
    Abstract: A bonding structure that may be used to form 3D-IC devices is formed using first oblong bonding pads on a first substrate and second oblong bonding pads one a second substrate. The first and second oblong bonding pads are laid crosswise, and the bond is formed. Viewed in a first cross-section, the first bonding pad is wider than the second bonding pad. Viewed in a second cross-section at a right angle to the first, the second bonding pad is wider than the first bonding pad. Making the bonding pads oblong and angling them relative to one another reduces variations in bonding area due to shifts in alignment between the first substrate and the second substrate. The oblong shape in a suitable orientation may also be used to reduce capacitive coupling between one of the bonding pads and nearby wires.

    Abstract: An electric connection structure and a method for fabricating the same are provided. The present invention provides a fixing thread fixed to a substrate and disposed on an upper surface of the substrate. The fixing thread is fixed to the substrate by shuttling between, binding, or penetrating through the upper surface and the bottom surface of the substrate. And then, a bare end of a signal line is fixed to the upper surface of the substrate by welding a solder thereby. When the solder is cooled down to solidify, the fixing thread generates a pull force applied on the solder pulling the solder toward the upper surface of the substrate.
