  • Patent number: 7986037
    Abstract: As a power feed route in a semiconductor chip, a power feed route which reduces antiresonance impedance in the frequency range of tens of MHz is to be realized thereby to suppress power noise in a semiconductor device. By inserting structures which raise the resistance in the medium frequency band into parts where the resistance is intrinsically high, such as power wiring in a semiconductor package and capacitor interconnecting electrode parts, the antiresonance impedance in the medium frequency band can be effectively reduced while keeping the impedance low at the low frequency.

  • Patent number: 7911063
    Abstract: In a semiconductor device according to an aspect of the invention, a direction in which a fourth metal interconnection layer located on a semiconductor layer is extended is orthogonal to a direction in which third interconnection layers ML30 and ML37 located on the fourth interconnection layer are extended. Thus, even in a case where a stress is applied from outside to bonding pads BP1 and BP2 located above, the stress is wholly dispersed by the third interconnection layers and the fourth interconnection layer which are laminated to intersect with each other, and stress concentration on a particular point can be relieved to restrain deterioration in semiconductor device strength to a minimum. Accordingly, it is possible to provide the semiconductor device having a structure in which productivity of the semiconductor device can be improved while the stress concentration applied from outside on the particular point of the bonding pad is relieved.

    Abstract: A memory cell for reducing the cost and complexity of modifying a revision identifier (ID) or default register values associated with an integrated circuit (IC) chip, and a method for manufacturing the same. The cell, which may be termed a “Meta-Memory Cell” (MMCEL), is implemented on metal layers only and utilizes a dual parallel metal ladder structure that traverses and covers each metal and via layer from the bottom to the top of the metal layer structure of the chip. One of the metal ladders is connected to a power supply at the bottom metal layer, corresponding to a logic 1, and another metal ladder is connected to ground at the bottom metal layer, corresponding to a logic 0. The output of the MMCEL can thus be inverted at any metal or via layer and can be inverted as often as required. Significant cost savings are achieved because a revision ID or default register bits may be modified by altering only those metal layers where design changes are necessary.

    Abstract: A main wall part is provided so as to surround an integrated circuit part. A sub-wall part which is in “L” shape is provided between each corner of the main wall part and the integrated circuit part. Therefore, even if the stress is concentrated due to heat treatment or the like, the stress is dispersed to the main wall part and the sub-wall part, and hence peeling between layers and a crack are unlikely to occur, as compared with the conventional art. Further, even if the crack and the like occur at the corner, moisture from the outside hardly reaches the integrated circuit part when the main wall part and the sub-wall part are coupled to each other. For this reason, it is possible to ensure an extremely high moisture resistance.

    Abstract: A rectangular-shaped interlevel connection structure is defined to electrically connect a first structure in a first chip level with a second structure in a second chip level. The rectangular-shaped interlevel connection structure is defined by an as-drawn cross-section having at least one dimension larger than a corresponding dimension of either the first structure, the second structure, or both the first and second structures. A dimension of the rectangular-shaped interlevel connection structure can exceed a normal maximum size in one direction in exchange for a reduced size in another direction. The rectangular-shaped interlevel connection structure can be placed in accordance with a gridpoint of a virtual grid defined by two perpendicular sets of virtual lines. Also, the first and/or second structures can be spatially oriented and/or placed in accordance with one or both of the two perpendicular sets of virtual lines.

  • Patent number: 7557436
    Abstract: Wiring lines for the supply of a voltage to feed a drive voltage to an integrated circuit formed in a semiconductor chip are disposed so as to cover a main surface of the semiconductor chip, so that, if the wiring lines are removed for the purpose of analyzing information stored in the semiconductor chip, the integrated circuit does not operates and it is impossible to analyze the information. Further, there is provided a processing detector circuit for detecting that the wiring lines have been tampered with. When the processing detector circuit detects a change in the sate of the wiring lines, the integrated circuit is reset. Thus, it is possible to improve the security of information stored on the card.

  • Patent number: 7511370
    Abstract: An electrical device includes electrical contact pads, a supply voltage bus and an interconnection circuit. The electrical contact pads receive a supply voltage, and the bus is electrically connected to the electrical contact pads. For each electrical contact pad, the interconnection circuit forms a redundant connection between the bus and the electrical contact pad. The electrical device may include a passivation layer that includes windows to establish electrical contact between the electrical contact pads and the supply voltage bus. This window may be elongated in a path that is generally aligned with the path along which the supply voltage bus extends.

  • Publication number: 20080303097
    Abstract: In one embodiment, relatively thin but wide metal bus strips overlying a high power FET are formed to conduct current to the source and drain narrow metal strips. A passivation layer is formed over the surface of the FET, and the passivation layer is etched to expose almost the entire top surface of the bus strips. A copper seed layer is then formed over the surface of the wafer, and a mask is formed to expose only the seed layer over the bus strips. The seed layer over the bus strips is then copper or gold electroplated to deposit a very thick metal layer, which effectively merges with the underlaying metal layer, to reduce on-resistance. The plating metal does not need to be passivated due to its thickness and wide line/space. Other techniques may also be used for depositing a thick metal over the exposed bus strips.

  • Publication number: 20080290495
    Abstract: As a power feed route in a semiconductor chip, a power feed route which reduces antiresonance impedance in the frequency range of tens of MHz is to be realized thereby to suppress power noise in a semiconductor device. By inserting structures which raise the resistance in the medium frequency band into parts where the resistance is intrinsically high, such as power wiring in a semiconductor package and capacitor interconnecting electrode parts, the antiresonance impedance in the medium frequency band can be effectively reduced while keeping the impedance low at the low frequency.
