  • Publication number: 20100283042
    Abstract: An electronic or electro-optic device has a first electrode, a second electrode spaced apart from the first electrode, and a dielectric layer disposed between the first and second electrodes. The dielectric layer has electrically insulating planar layers with intercalated ions therebetween such that the electrically insulating planar layers provide a barrier to impede movement of the intercalated ions to the first and second electrodes under an applied voltage while permitting a polarization of the dielectric layer while in operation.

  • Patent number: 7820488
    Abstract: A microelectronic device is made of a semiconductor substrate, a heat generating component in a layer thereof, and a body within the remaining semiconductor substrate. The body is made of materials which have a high thermal inertia and/or thermal conductivity. When high thermal conductivity materials are used, the body acts to transfer the heat away from the substrate to a heat sink.

  • Publication number: 20100264512
    Abstract: A semiconductor device is made by providing an integrated passive device (IPD). Through-silicon vias (TSVs) are formed in the IPD. A capacitor is formed over a surface of the IPD by depositing a first metal layer over the IPD, depositing a resistive layer over the first metal layer, depositing a dielectric layer over the first metal layer, and depositing a second metal layer over the resistive and dielectric layers. The first metal layer and the resistive layer are electrically connected to form a resistor and the first metal layer forms a first inductor. A wafer supporter is mounted over the IPD using an adhesive material and a third metal layer is deposited over the IPD. The third metal layer forms a second inductor that is electrically connected to the capacitor and the resistor by the TSVs of the IPD. An interconnect structure is connected to the IPD.

  • Patent number: 7816716
    Abstract: Source/drain diffusion layers and a channel region are formed in a polysilicon thin film formed on a substrate made of glass or the like, and furthermore, a gate electrode 6 is formed via a gate insulating film. A silicon hydronitride film is formed on the interlayer dielectric film, whereby the hydrogen concentration in an active element region including a switching thin film transistor can be maintained at a high level, and Si—H bonds in the silicon thin film become stable. In addition, by providing a ferroelectric film on the silicon hydronitride film via a lower electrode formed of a conductive oxide film, whereby the oxygen concentration of the ferroelectric capacitive element layer can be maintained at a high level, and generation of oxygen deficiency in the ferroelectric film is prevented.

  • Patent number: 7785977
    Abstract: A thin film capacitor including a substrate, a capacitor portion having an upper conductor, a lower conductor, and a dielectric thin film, and a resin protective layer for protecting the capacitor portion. A barrier layer is interposed between the capacitor portion and the resin protective layer. The barrier layer includes a crystalline dielectric barrier layer formed in contact with the capacitor portion and having the same composition system as the dielectric thin film, and an amorphous inorganic barrier layer formed on the surface of the crystalline dielectric barrier layer and composed of silicon nitride having non-conductivity. The inorganic barrier layer prevents deterioration in the properties of the dielectric thin film by blocking diffusion of the constituent elements of the inorganic barrier layer toward the capacitor portion.
