    摘要: Microelectronic systems having embedded heat dissipation structures are disclosed, as are methods for fabricating such microelectronic systems. In various embodiments, the method includes the steps or processes of obtaining a substrate having a tunnel formed therethrough, attaching a microelectronic component to a frontside of the substrate at a location covering the tunnel, and producing an embedded heat dissipation structure at least partially within the tunnel after attaching the microelectronic component to the substrate. The step of producing may include application of a bond layer precursor material into the tunnel and onto the microelectronic component from a backside of the substrate. The bond layer precursor material may then be subjected to sintering process or otherwise cured to form a thermally-conductive component bond layer in contact with the microelectronic component.

    摘要: During the manufacture of a semiconductor package, a semiconductor wafer including a plurality of bond pads on a surface of the wafer is provided and the surface of the wafer is covered with a dielectric material to form a dielectric layer over the bond pads. Portions of the dielectric layer corresponding to positions of the bond pads are removed to form a plurality of wells, wherein each well is configured to form a through-hole between top and bottom surfaces of the dielectric layer for exposing each bond pad. A conductive material is then deposited into the wells to form a conductive layer between the bond pads and a top surface of the dielectric layer. Thereafter, the semiconductor wafer is singulated to form a plurality of semiconductor packages.

    摘要: A display device can include a substrate including a display area, on which an input image is displayed, and a pad part including a convex portion and a concave portion that are alternately positioned outside the display area and have a height difference between them, and a circuit element attached to the pad part and including a bump inserted into the concave portion of the pad part. The pad part can further include a lower pad electrode electrically connected to a signal line extended from the display area, a first insulating layer disposed on the lower pad electrode in the convex portion, and an upper pad electrode disposed on the first insulating layer, connected to the lower pad electrode through a first contact hole penetrating the first insulating layer and extending into at least a portion of the concave portion.
