  • Patent number: 12255126
    Abstract: There are provided a semiconductor and a method of fabricating the same. The semiconductor device may include a second semiconductor substrate directly bonded to a first semiconductor substrate. The first semiconductor substrate may include a first through via with an end portion protruding through a first top surface, the first top surface being a top surface of a first semiconductor substrate body, a liner extending to partially expose a side surface of the end portion of the first through via, and a first diffusion barrier layer. The liner may include a third top surface that is positioned at a lower height than a second top surface, the second top surface being a top surface of the end portion of the first through via and substantially equal to the first top surface. Alternatively, the liner may include a third surface positioned at a height that is lower than the second top surface and higher than the first top surface.

  • Publication number: 20240105656
    Abstract: A packaging device including bumps and a method of manufacturing the packaging device are presented. In the method of manufacturing a packaging device, a dielectric layer that covers a packaging base is formed and a lower layer is formed over a packaging base including first and second connecting pads. A plurality of dummy bumps that overlaps with the dielectric layer is formed. A sealing pattern that covers the dummy bumps, filling areas between the dummy bumps, is formed. A lower layer pattern in which the plurality of dummy bumps have been disposed is formed by removing portions of the lower layer that are exposed and do not overlap with the sealing pattern.
