    Abstract: An integrated circuit structure includes a plurality of insulator layers (connected to each other) that form a laminated structure. Further included are via openings within each of the insulator layers, and conductive via material within the via openings. The conductive via material within corresponding via openings of adjacent insulator layers are electrically connected to form continuous electrical via paths through the insulator layers between the top surface and the bottom surface of the laminated structure. Within each of the continuous electrical via paths, the via openings are positioned relative to each other to form a diagonal structural path of the conductive via material through the laminated structure. The corresponding via openings of the adjacent insulator layers partially overlap each other. The diagonal structural paths are non-perpendicular to the top surface and the bottom surface.

  • Patent number: 8444043
    Abstract: An array of solder balls is attached to solder pads of one of a first substrate and a second substrate. After aligning the array of solder balls relative to solder pads of the other of the first substrate and the second substrate, a thermal-mass-increasing fixture is placed on a surface of the second substrate to form an assembly of the first substrate, the second substrate, and the array of the solder balls therebetween, and the thermal-mass-increasing fixture. The thermal-mass-increasing fixture is in physical contact with at least a surface of a periphery of the second substrate. The thermal-mass-increasing fixture reduces the cool-down rate of peripheral solder balls after a reflow step, thereby increasing time for deformation of peripheral solder balls during the cool-down and reducing the mechanical stress on the solder balls after the cool-down.
