  • Publication number: 20240170475
    Abstract: A method for manufacturing a semiconductor device includes providing a first integrated circuit element including a first semiconductor substrate and a first wiring layer, providing a second integrated circuit element including a second semiconductor substrate and a second wiring layer, bonding the first insulating layer and the second insulating layer to each other, and bonding the first electrode and the second electrode to each other. The first insulating layer contains an inorganic insulating material. A plurality of first openings recessed toward the first semiconductor substrate from a bonding surface bonded to the second insulating layer are provided at positions in the first insulating layer in the first wiring layer different from an arrangement position of the first electrode, and the plurality of first openings discontinuously surround the first electrode.

  • Publication number: 20240170447
    Abstract: A method for manufacturing a semiconductor device includes providing a first integrated circuit element including a first semiconductor substrate, a first insulating film, and a first electrode, providing a second integrated circuit element including a second semiconductor substrate, a second insulating film, and a second electrode, bonding the first insulating film and the second insulating film to each other, and bonding the first electrode and the second electrode to each other. The first insulating film includes a first inorganic insulating layer and a first organic insulating layer. The second insulating film includes a second inorganic insulating layer and a second organic insulating layer. The thickness of the first organic insulating layer is smaller than the thickness of the first inorganic insulating layer, and the thickness of the second organic insulating layer is smaller than the thickness of the second inorganic insulating layer.
