  • Patent number: 8759213
    Abstract: A method for forming a metal-semiconductor alloy layer uses particular thermal annealing conditions to provide a stress free metal-semiconductor alloy layer through interdiffusion of a buried semiconductor material layer and a metal-semiconductor alloy forming metal layer that contacts the buried semiconductor material layer within an aperture through a capping layer beneath which is buried the semiconductor material layer. A resulting semiconductor structure includes the metal-semiconductor alloy layer that further includes an interconnect portion beneath the capping layer and a contiguous via portion that penetrates at least partially through the capping layer. Such a metal-semiconductor alloy layer may be located interposed between a substrate and a semiconductor device having an active doped region.

  • Patent number: 8754534
    Abstract: A memory card has a wiring board, four memory chips stacked on a main surface of the wiring board, and a controller chip and an interposer mounted on a surface of the memory chip of the uppermost layer. The memory chips are stacked on the surface of the wiring board so that their long sides are directed in the same direction as that of the long side of the wiring board. The memory chip of the lowermost layer is mounted on the wiring board in a dislocated manner by a predetermined distance in a direction toward a front end of the memory card so as not to overlap the pads of the wiring board. The three memory chips stacked on the memory chip of the lowermost layer are disposed so that their short sides on which pads are formed are located at the front end of the memory card.

  • Patent number: 8742603
    Abstract: A backside mold configuration (BSMC) process for manufacturing packaged integrated circuits includes applying a mold compound to a side of a packaging substrate opposite an attached die. The mold compound is deposited on a dielectric (such as photo resist). The mold compound and dielectric are patterned after coupling a die to the packaging substrate to expose a contact pad of the packaging substrate. After patterning the mold compound and dielectric, a packaging connection is coupled to contact pads through the mold compound and dielectric. The mold compound surrounding the packaging connection reduces warpage of the packaging substrate during processing. Additionally, patterning the dielectric after attaching the die improves reliability of the packaging connection.

  • Patent number: 8735282
    Abstract: The present invention discloses a semiconductor device and a manufacturing method therefor. Conventionally, platinum is deposited in a device substrate to suppress diffusion of nickel in nickel silicide. However, introducing platinum by means of deposition makes the platinum only stay on the surface but fails to effectively suppress the diffusion of nickel over a desirable depth. According to the present invention, a semiconductor device is formed by implanting platinum into a substrate and forming NiSi in a region of the substrate where platinum is implanted. With the present invention, platinum can be distributed over a desirable depth range so as to more effectively suppress nickel diffusion.
