  • Patent number: 9177813
    Abstract: In MOSFET having SBD as a protection element, a TiW (alloy having tungsten as a main component) film is used as an aluminum-diffusion barrier metal film below an aluminum source electrode in order to secure properties of SBD. The present inventors have found that a tungsten-based barrier metal film is in the form of columnar grains having a lower barrier property than that of a titanium-based barrier metal film such as TiN so that aluminum spikes are generated relatively easily in a silicon substrate. In the present invention, when a tungsten-based barrier metal film is formed by sputtering as a barrier metal layer between an aluminum-based metal layer and a silicon-based semiconductor layer therebelow, the lower layer is formed by ionization sputtering while applying a bias to the wafer side and the upper layer is formed by sputtering without applying a bias to the wafer side.

The hybrid films are characterized by a good degree of control of the architecture at the nanoscale level, where the weakness(es) of each component are offset by the strengths of the other components. By rational design of the structure and using simple and locate-cost fabrication methods, hybrid films with sheet resistance of 26 ohm/sq and optical transmittance (at ?=550 nm) of 83% for reduced graphene oxide/silver nanowire films, and 64 ohm/sq and optical transmittance of 93.6% for monolayer graphene/silver nanowire films have been fabricated. These values are comparable to transparent conductive films based on indium tin oxide but are now able to be used in flexible electronics due to their good mechanical properties.

  • Patent number: 8168288
    Abstract: In a multilayer ceramic substrate manufactured by a non-shrinking process, a bonding strength of an external conductive film formed on a primary surface of the multilayer ceramic substrate is increased. After a laminate of a multilayer ceramic substrate is formed from first ceramic layers and second shrinkage suppressing ceramic layers, and an underlayer is formed along one primary surface of the multilayer ceramic substrate, an external conductive film is formed on the underlayer. A non-sintering ceramic material powder in a non-sintered state is included in both the external conductive film and the underlayer, and this non-sintering ceramic material powder is fixed due to diffusion of a glass component from the first ceramic layers.

  • Patent number: 8134073
    Abstract: Bond wires for integrated circuits are implemented using a variety of methods. Using one such method, a composite bond wire is produced for use in an integrated circuit. A conductive material is melted and mixed with a material of particles less than 100 micrometers in size to create a mixture. The mixture is used to create the composite bond wire. A composite wire having an inner core and an outer layer having a higher conductivity than the inner core is also provided. The outer layer is designed to be thicker than the skin depth at the operating frequency for carrying AC signals.
