Abstract: An electronic package structure and method use a conductive strip to bond die-to-die, die-to-lead, chip carrier-to-lead, or lead-to-lead. A conductive strip may carry greater current than a bonding wire, and thus may replace several bonding wires. The bonding of the conductive strip may be carried out by an SMT process, and thus requires lower cost than wire bonding processes. A conductive strip may be bonded to more than two dice or leads to save more bonding wires. A conductive strip is stronger than a bonding wire, and thus lowers the possibility of being broken.

Abstract: A lower interconnection is provided on a semiconductor substrate. A MIM capacitive element is provided on a first interlayer insulation film in which the lower interconnection is buried, and includes a lower electrode, an upper electrode, and a dielectric film sandwiched therebetween. An upper interconnection is provided on a second interlayer insulation film in which the MIM capacitive element is buried. A contact electrically connects the lower electrode and the upper interconnection. The lower electrode is mainly formed of Al, so that they are lower in electrical resistance than barrier metal, and also low in stress value. Therefore, it becomes possible to widen the area of the lower electrode for electrically connecting the contact while restraining their influences on charge accumulation and close contact between the lower electrode and the insulation film. In addition, since the electrical resistance is lowered, the thickness of the lower electrode can be increased.

Because there is no solder mask layer between the bottom of the passive component and the substrate, the gap between the passive component and the substrate will become wider. Hence, remaining flux can be entirely removed in order to increase the yield rate of the subsequent high temperature process.

Abstract: An electrical bus grid (108) for an application specific integrated circuit (ASIC) chip (102). The bus grid is generally formed by mutually orthogonal wires (28′, 30′) contained within two metal layer (M6′, M7′). The bus grid is located within each of a plurality of contiguous rectangular regions (32′), which are defined by electrical contacts (12′). Due to the regular pattern of the electrical contacts, the bus grids within the contiguous rectangular regions are identical to one another, such that the bus grid forms a repeatable pattern. The widths of the wires in each of the two metal layers vary depending upon the magnitude of the current carried by the corresponding wire. The magnitude of the current in the power bus may be determined by simulation and modeling performed prior to placement of cells (e.g., 18, 20, 22) within the ASIC chip.

Abstract: A interconnect structure is provided having a conductor with enhanced thickness. The conductor includes an upper portion and a lower portion, wherein the lower portion geometry is sufficient to increase the current-carrying capacity beyond that provided by the upper portion. The lower portion is formed by filling a trench within an upper dielectric region, and the upper portion is formed by selectively removing a conductive material from the upper dielectric surface except for regions directly above the lower portion. The upper and lower portions thereby form a conductor of enhanced cross-section which can be produced by modifying a via-etch mask, rather than having to reconfigure and/or move interconnect features formed by a metal mask.

Abstract: An integrated circuit chip wiring structure having crossover and contact capability without an interlock via layer and a method of making the wiring structure all disclosed. The method utilizes a multi-damascene approach, using the standard damascene processing steps to wire the first, then metallization layer, then providing the second, thick metallization layer with first regions for metal wire. A conformal coating is deposited, filling the second regions but not the first regions. When an etch is performed, the layers underlying the second regions are exposed but not those underlying the second regions. Therefore, it is possible to selectively expose the metal lines in the first layer so that electrical connection is made with the metal wire of the second layer in the exposed areas. Electrical isolation is maintained in the narrower, second regions of metal wire.

High speed potted integrated circuits may thereby be provided.

Abstract: A particular layout (38) of transistors along a continuous conductor line (54), such as the transistors in a CMOS inverter, has been found which reduces breaks or voids in the conductor line due to electromigration of the conductor atoms from predominantly unidirectional current flows. The conductor line may be a metal line. By alternating the two types of transistors, p- and n-type (40, 41, 46 & 47), along the length of the metal line, almost the entire length of the line can be changed to one with bidirectional current flow which significantly reduces the mean-time-to-failure for electromigration-related damage. The layout arrangement will find greater advantage for large transistors, long metal lines, relatively large unidirectional current flows and devices that run at high frequency, such as clock drivers.

Abstract: Operating characteristics of an electronics device in which alternating currents flow are improved by reducing positive electromagnetic coupling between currents.

Abstract: The feeds to the emitter, base, and collector of an RF power transistor (source, drain, gate feeds of an RF FET) are configured so that negative mutual coupling therebetween is enhanced and positive mutual coupling therebetween is reduced. The emitter and base feeds include elongated portions which are generally parallel to each other with bonding pads provided on the elongated portions so that emitter and base currents flow in the same direction in the elongated portions and in the same direction as collector currents below. Interdigitated contact fingers extend from the elongated portions and contact the emitter region and the base region, respectively. When positive coupling of collector current and emitter current to the controlling base current is reduced or eliminated, the major thermal imbalance problem of operating RF transistors is also reduced or eliminated. Performance, linearity, efficiency, gain, and ruggedness are all enhanced in devices designed to utilize this invention.
