  • Patent number: 7728376
    Abstract: HfO2 films and ZrO2 films are currently being developed for use as capacitor dielectric films in 85 nm technology node DRAM. However, these films will be difficult to use in 65 nm technology node or later DRAM, since they have a relative dielectric constant of only 20-25. The dielectric constant of such films may be increased by stabilizing their cubic phase. However, this results in an increase in the leakage current along the crystal grain boundaries, which makes it difficult to use these films as capacitor dielectric films. To overcome this problem, the present invention dopes a base material of HfO2 or ZrO2 with an oxide of an element having a large ion radius, such as Y or La, to increase the oxygen coordination number of the base material and thereby increase its relative dielectric constant to 30 or higher even when the base material is in its amorphous state. Thus, the present invention provides dielectric films that can be used to form DRAM capacitors that meet the 65 nm technology node or later.

    Abstract: Parallel plate tunable varactors having a bulk capacitance contribution to a total capacitance increased compared to a fringing capacitance contribution are disclosed. The contribution of the bulk capacitance to the total capacitance of an exemplary BST varactor is increased by increasing the area/perimeter ratio of the active region, thereby improving the tunability and other properties of the varactor. In an exemplary embodiment, an active region of the varactor has a lateral shape with a perimeter that is less than a perimeter of an equivalent area square. In various exemplary embodiments, the shape of the active region may be substantially circular or substantially octagonal. Methods for fabricating and designing such varactors are also disclosed.

In a diode in which a P anode layer and an anode electrode are formed at a side of a right face of an N? drift layer, and an N+ cathode layer and a cathode electrode are formed at a side of a back face of the N? drift layer, an N cathode buffer layer is formed thick compared with the N+-type cathode layer between the N?-type drift layer and the N+ cathode layer, the buffer layer being high in concentration compared with the N? drift layer, and low compared with the N+ cathode layer. When a reverse bias voltage is applied, a depletion layer is stopped in the middle of the N cathode buffer layer, and thus prevented from reaching the N+ cathode layer, so that the leakage current is suppressed.

The leadframe may include a plurality of elongated electrical leads, extending from a first side of the leadframe, beneath the die, and terminating at a second side of the leadframe adjacent to the bond pads along the single edge of the die. The leadframe may further include a dielectric spacer layer on the elongated leads. Spacing the semiconductor die from the elongated leads using the spacer layer reduces the parasitic capacitance and/or inductance of the semiconductor package formed thereby.

  • Patent number: 7728412
    Abstract: A method of making a semiconductor device including a semiconductor chip having a plurality of pads, and a lead frame having a plurality of leads. Each of the plurality of leads has a mounting surface for mounting the semiconductor device, a wire connection surface having a thick portion, and a thin portion whose thickness is thinner than the thick portion. The length of each wire connection surface was furthermore formed shorter than the mounting surface, by arranging so that the thin portion of each lead dives below the semiconductor chip, securing the length of the mounting surface of each lead, a distance from the side face of the semiconductor chip to the side face of a molded body of the semiconductor device being shortened as much as possible, and the package size is brought close to chip size, with miniaturization of QFN.

  • Patent number: 7728414
    Abstract: A power QFN package includes signal leads, a die pad, support leads, and an adhesive for die bonding. These elements are encapsulated with a resin encapsulant. The lower parts of the signal leads are exposed from the resin encapsulant to function as external electrodes. A middle part of the die pad is formed at a higher level than a peripheral part thereof. This permits the formation of through holes in a thin part of the die pad. This enhances the degree of flexibility in the size of a semiconductor chip and the moisture resistance thereof.

  • Patent number: 7728423
    Abstract: A plurality of IC regions are formed on a semiconductor wafer, which is cut into individual chips incorporating ICs, wherein wiring layers and insulating layers are sequentially formed on a silicon substrate. In order to reduce height differences between ICs and scribing lines, a planar insulating layer is formed to cover the overall surface with respect to ICs, seal rings, and scribing lines. In order to avoid occurrence of breaks and failures in ICs, openings are formed to partially etch insulating layers in a step-like manner so that walls thereof are each slanted by prescribed angles ranging from 20° to 80°. For example, a first opening is formed with respect to a thin-film element section, and a second opening is formed with respect to an external-terminal connection pad.
