    Abstract: The present invention provides a multilayered power supply line suitable for use in a semiconductor integrated circuit and a layout method thereof. In the multilayered power supply line (10) for the semiconductor integrated circuit, a top metal (12) and a second metal (14) are electrically connected to each other by through holes (18). Further, a capacitor metal (16) is electrically connected to the top metal (12) by through holes (20) to thereby make the top metal (12), the second metal (14) and the capacitor metal (16) identical in potential to one another, whereby the multilayered power supply line functions as a power supply line based on normal wiring metals without functioning as a capacitor. It is thus possible to supply power with reduced impedance.

  • Patent number: 7286366
    Abstract: A multilayer substrate assembly (80) includes at least one embedded component (52) within a plurality of stacked pre-processed substrates. Each pre-processed substrate can have a core dielectric (14), patterned conductive surfaces (12 and 16) on opposing sides of the core dielectric, and at least one hole (18) in each of at least two adjacently stacked pre-processed substrates such that at least two holes are substantially aligned on top of each other forming a single hole (19). The assembly further includes a processed adhesive layer (48) between top and bottom surfaces of respective pre-processed substrates. The embedded component is placed in the single hole and forms a gap (67 & 66) between the embedded component and a peripheral wall of the single hole. When the assembly is biased, the processed adhesive layer fills the gap to form the assembly having the embedded component cross-secting the plurality of pre-processed substrates.
