  • Patent number: 6589851
    Abstract: In one aspect, the invention provides a method of forming an electrical connection in an integrated circuitry device. According to one preferred implementation, a diffusion region is formed in semiconductive material. A conductive line is formed which is laterally spaced from the diffusion region. The conductive line is preferably formed relative to and within isolation oxide which separates substrate active areas. The conductive line is subsequently interconnected with the diffusion region. According to another preferred implementation, an oxide isolation grid is formed within semiconductive material. Conductive material is formed within the oxide isolation grid to form a conductive grid therein. Selected portions of the conductive grid are then removed to define interconnect lines within the oxide isolation grid. According to another preferred implementation, a plurality of oxide isolation regions are formed over a semiconductive substrate.

  • Publication number: 20030122246
    Abstract: An integrated chip package structure and method of manufacturing the same is by adhering dies on a silicon substrate and forming a thin-film circuit layer on top of the dies and the silicon substrate. Wherein the thin-film circuit layer has an external circuitry, which is electrically connected to the metal pads of the dies, that extends to a region outside the active surface of the dies for fanning out the metal pads of the dies. Furthermore, a plurality of active devices and an internal circuitry is located on the active surface of the dies. Signal for the active devices are transmitted through the internal circuitry to the external circuitry and from the external circuitry through the internal circuitry back to other active devices. Moreover, the chip package structure allows multiple dies with different functions to be packaged into an integrated package and electrically connecting the dies by the external circuitry.

  • Patent number: 6569727
    Abstract: A 16 megabit (224) or greater density single deposition layer metal Dynamic Random Access Memory (DRAM) part is described which allows for a die that fits within an industry-standard 300 ml wide SOJ (Small Outline J-wing) package or a TSOP (Thin, Small Outline Package) with little or no speed loss over previous double metal deposition layered 16 megabit DRAM designs. This is accomplished using a die architecture which allows for a single metal layer signal path, together with the novel use of a lead frame to remove a substantial portion of the power busing from the die, allowing for a smaller, speed-optimized DRAM. The use of a single deposition layer metal results in lower production costs, and shorter production time.

    Abstract: A Three-Dimensional Structure (3DS) Memory allows for physical separation of the memory circuits and the control logic circuit onto different layers such that each layer may be separately optimized. One control logic circuit suffices for several memory circuits, reducing cost. Fabrication of 3DS memory involves thinning of the memory circuit to less than 50 &mgr;m in thickness and bonding the circuit to a circuit stack while still in wafer substrate form. Fine-grain high density interlayer vertical bus connections are used. The 3DS memory manufacturing method enables several performance and physical size efficiencies, and is implemented with established semiconductor processing techniques.

  • Patent number: 6534393
    Abstract: A method for making low sheet resistance local metal interconnections and improved transistor performance is described. The method involves patterning a polysilicon layer and a silicon nitride (Si3N4) cap layer over device areas to form FET gate electrodes, and the patterned polysilicon extends over the field oxide regions to form portions of the local interconnections. After forming source/drain areas and sidewall spacers on the FET gate electrodes, a silicon oxide (SiO2) insulating layer is deposited and polished back to the Si3N4 cap. The Si3N4 is then selectively removed over the patterned polysilicon layer, leaving recesses in the SiO2 layer. After etching contact openings in the SiO2 layer to the substrate, a high electrically conducting metal layer, having a barrier layer, is deposited and patterned to complete the local interconnections.

  • Patent number: 6406975
    Abstract: A method of manufacturing a shallow trench isolation (STI) with an air gap that is formed by decomposing an organic filler material through a cap layer. A pad layer and a barrier layer are formed over the substrate. The pad layer and the barrier layer are patterned to form a trench opening. We form a trench in substrate by etching through the trench opening. A first liner layer is formed on the sidewalls of the trench. A second liner layer over the barrier layer and the first liner layer. A filler material is formed on the second liner layer to fill the trench. In an important step, a cap layer is deposited over the filler material and the second liner layer. The filler material is subjected to a plasma and heated to vaporize the filler material so that the filler material diffuses through the cap layer to form a gap. An insulating layer is deposited over the cap layer. The insulating layer is planarized. The barrier layer is removed.

  • Patent number: 6344399
    Abstract: In one aspect, the invention provides a method of forming an electrical connection in an integrated circuitry device. According to one preferred implementation, a diffusion region is formed in semiconductive material. A conductive line is formed which is laterally spaced from the diffusion region. The conductive line is preferably formed relative to and within isolation oxide which separates substrate active areas. The conductive line is subsequently interconnected with the diffusion region. According to another preferred implementation, an oxide isolation grid is formed within semiconductive material. Conductive material is formed within the oxide isolation grid to form a conductive grid therein. Selected portions of the conductive grid are then removed to define interconnect lines within the oxide isolation grid. According to another preferred implementation, a plurality of oxide isolation regions are formed over a semiconductive substrate.

  • Patent number: 6326293
    Abstract: A plug is formed of polysilicon, or other oxidizable conductor. Chemical-mechanical polishing is performed, with a polish stop layer defining the top of the dielectric layer. The upper portion of the polysilicon is oxidized to a controlled depth, then the oxidized portion is removed by an etch, followed by removal of the polish stop layer. The plug thus formed protrudes a controllable distance above the surrounding dielectric, providing good contact to subsequent conductive layers.

  • Patent number: 6313024
    Abstract: In one embodiment of the invention, conductive support structures (112) are formed within an interlevel dielectric layer. The conductive support structures (112) lie within the bond pad region (111) of the integrated circuit and provide support to portions of the interlevel dielectric layer that have a low Young's modulus. The conductive support structures (112) are formed using the same processes that are used to form metal interconnects in the device region (109) of the integrated circuit, but they are not electrically coupled to semiconductor devices that lie within the device region (109). Conductive support structures (114) are also formed within the scribe line region (104) to provide support to the interlevel dielectric layer in this region of the integrated circuit.
