Insulating Coating Patents (Class 257/632)
  • Patent number: 7723812
    Abstract: Embodiments of the present invention generally relate to a device that has an improved usable lifetime due to the presence of a lubricant that reduces the likelihood of stiction occurring between the various moving parts in an electromechanical device. Embodiments of the present invention also generally include a device, and a method of forming a device, that has one or more surfaces or regions that have a volume of lubricant disposed thereon that acts as a ready supply of “fresh” lubricant to prevent stiction occurring between interacting components found within the device. In one aspect, components within the volume of lubricant form a gas or vapor phase that reduces the chances of stiction-related failure in the formed device. In one example, aspects of this invention may be especially useful for fabricating and using micromechanical devices, such as MEMS devices, NEMS devices, or other similar thermal or fluidic devices.

    Abstract: Exemplary embodiments provide a method for fabricating an integrated circuit (IC) device with reduced streak defects. In one embodiment, the IC device structure can be formed having a first pad oxide-based layer on a front side of a semiconductor substrate and having an oxide-nitride-based structure on a backside of the semiconductor substrate. The IC device structure can be etched to remove a nitride-related material from the backside oxide-nitride-based structure, and further to remove the first pad oxide-based layer from the front side of the semiconductor substrate. On the removed front side of the semiconductor substrate a second pad oxide-based layer can be formed, e.g., for forming an isolation structure for device component or circuitry isolation.

  • Publication number: 20100109130
    Abstract: A thin oxide film is formed by atomic layer deposition (ALD) onto a substrate by exposing the substrate to a first precursor comprising a metal organic alkoxide or amide or heteroleptic derivatives thereof and subsequently exposing the substrate to a second precursor comprising an ALD compatible carboxylic acid or carboxyl acid derivative compound. The sequential exposure to the first and second precursors may be repeated until a sufficient film thickness of an oxide of the metal has been deposited on the substrate. This process allows growth of an oxide thin film or nanostructure, on any suitable substrate. It permits formation of a high-? dielectric oxide thin film on the substrate with similar dielectric properties to a much thinner SiO2 film. Furthermore, the films grown can exhibit very good structural and physical properties. The process also provides high self-control of thin film growth with high reproducibility and reliability.

    Abstract: A method for forming self-assembled patterns on a substrate surface is provided. First, a block copolymer layer, which comprises a block copolymer having two or more immiscible polymeric block components, is applied onto a substrate that comprises a substrate surface with a trench therein. The trench specifically includes at least one narrow region flanked by two wide regions, and wherein the trench has a width variation of more than 50%. Annealing is subsequently carried out to effectuate phase separation between the two or more immiscible polymeric block components in the block copolymer layer, thereby forming periodic patterns that are defined by repeating structural units. Specifically, the periodic patterns at the narrow region of the trench are aligned in a predetermined direction and are essentially free of defects. Block copolymer films formed by the above-described method as well as semiconductor structures comprising such block copolymer films are also described.

  • Publication number: 20090273061
    Abstract: A double-structure silicon on insulator (SOI) substrate with a silicon layer, an insulation film (silicon oxide film), a silicon layer, and an insulation film in this order from the side of the surface. The upper-layer insulation film is formed so as to have a uniform distribution of depth while the lower-layer insulation film is formed so as to have a non-uniform distribution of depth so that a thick portion may be formed in the silicon layer along a predetermined path. The refractive index of Si is 3.5 and the refractive index of SiO2 is 1.5. The thick portion of the silicon layer provides a core and the insulation films corresponding to this thick portion provide clads, thereby forming an optical waveguide along the predetermined path. The silicon layer at the side of the surface has a uniform thickness, thereby enabling characteristics of MOS devices fabricated on various portions of the silicon layer to be met with each other easily and facilitating a design of the electrical device as a whole.

  • Patent number: 7608912
    Abstract: The present invention provides a technique for reducing stress or stress gradients in highly sensitive device regions, such as cache areas, while still providing high transistor performance in logic areas by correspondingly providing contact etch stop layers with compressive and tensile stress for P-channel transistors and N-channel transistors in these logic areas. Consequently, a reduced failure rate may be obtained.

  • Patent number: 7605436
    Abstract: A method contains the steps of (a) heating a silicon substrate in a reaction chamber; and (b) supplying film-forming gas containing source gas, nitridizing gas, and nitridation enhancing gas to a surface of the heated silicon substrate, to deposit on the silicon substrate an Hf1-xAlxO:N film (0.1<x<0.3) having a higher specific dielectric constant than that of silicon oxide, and incorporating N, by thermal CVD. The method can form an oxide film of Hf1-xAlxO (0<x<0.3) having desired characteristics, as a gate insulation film.

  • Publication number: 20090230515
    Abstract: A well region in which an insulated gate semiconductor element is formed is a diffusion region, and an impurity concentration of the well region is lower toward its bottom portion. This leads to a problem of increased resistance. Therefore, particularly, an insulated gate semiconductor element having an up-drain structure has a problem of increased on-resistance. A p type well region is formed by stacking two p type impurity regions on one another. The p type impurity regions are allowed to serve as the p type well region by sequentially stacking n type semiconductor layers, on one another, having p type impurities implanted into their surfaces and simultaneously diffusing the impurities by heat treatment. In this way, it is possible to obtain the p type well region in which an impurity concentration sufficient to secure a desired breakdown voltage is maintained approximately uniform up to a desired depth.

  • Patent number: 7589397
    Abstract: A system and method is disclosed for using a differential wet etch stop technique to provide a uniform oxide layer over a metal layer in a laser trimmed fuse. A layer of boron doped oxide with a slow etch rate is placed over the metal layer. A layer of phosphorus doped oxide with a fast etch rate is placed over the boron doped oxide. The time period required for a wet etch process to etch through the phosphorus doped oxide is calculated. The wet etch process is then applied to the phosphorus doped oxide for the calculated time period. The wet etch process slows significantly when it reaches the boron doped oxide. This method forms a uniform layer of boron doped oxide over the metal layer.

  • Publication number: 20090224373
    Abstract: When an integrated circuit having an interlayer insulation film built up on top of a wiring layer is subjected to a heat treatment, it is unlikely that a void formed in the interlayer insulation film will rupture in a portion wherein are connected a narrow gap between wirings and a wide open part contiguous therewith. A corner part of a wiring positioned at a portion where a gap and an open part are connected is chamfered, and an end part of the gap is shaped so as to widen toward the open part. Providing the widening end part in the gap thus mitigates any discontinuity in the built up interlayer insulation film between the gap and the open part. As a result, the interlayer insulation film does not readily seal off an end of a void formed in the gap.
