  • Publication number: 20150349004
    Abstract: An integrated circuit system includes a first device wafer bonded to a second device wafer at a bonding interface of dielectrics. Each wafer includes a plurality of dies, where each die includes a device, a metal stack, and a seal ring that is formed at an edge region of the die. Seal rings included in dies of the second device wafer each include a first conductive path provided with metal formed in a first opening that extends from a backside of the second device wafer, through the second device wafer, and through the bonding interface to the seal ring of a corresponding die in the first device wafer.

  • Publication number: 20150295007
    Abstract: An image sensor pixel includes a photosensitive element, a floating diffusion region, a transfer gate, a dielectric charge trapping region, and a first metal contact. The photosensitive element is disposed in a semiconductor layer to receive electromagnetic radiation along a vertical axis. The floating diffusion region is disposed in the semiconductor layer, while the transfer gate is disposed on the semiconductor layer to control a flow of charge produced in the photosensitive element to the floating diffusion region. The dielectric charge trapping device is disposed on the semiconductor layer to receive electromagnetic radiation along the vertical axis and to trap charges in response thereto. The dielectric charge trapping device is further configured to induce charge in the photosensitive element in response to the trapped charges. The first metal contact is coupled to the dielectric charge trapping device to provide a first bias voltage to the dielectric charge trapping device.

  • Patent number: 8603877
    Abstract: Some embodiments include dielectric structures. The structures include first and second portions that are directly against one another. The first portion may contain a homogeneous mixture of a first phase and a second phase. The first phase may have a dielectric constant of greater than or equal to 25, and the second phase may have a dielectric constant of less than or equal to 20. The second portion may be entirely a single composition having a dielectric constant of greater than or equal to 25. Some embodiments include electrical components, such as capacitors and transistors, containing dielectric structures of the type described above. Some embodiments include methods of forming dielectric structures, and some embodiments include methods of forming electrical components.

  • Publication number: 20130256509
    Abstract: Techniques for providing a pixel cell which includes two source follower transistors. In an embodiment, a first source follower transistor of a pixel cell and a second source follower transistor of the pixel cell are coupled in parallel with one another, where the source follower transistors are each coupled via their respective gates to a floating diffusion node of the pixel cell. In another embodiment, the first source follower transistor and second source follower transistor each operate based on a voltage of the floating diffusion node to provide a respective component of an amplification signal, where the pixel cell outputs an analog signal based on the amplification signal.
