    摘要: High optical efficiency CMOS image sensors capable of sustaining pixel sizes less than 1.2 microns are provided. Due to high photodiode fill factors and efficient optical isolation, microlenses are unnecessary. Each sensor includes plural imaging pixels having a photodiode structure on a semiconductor substrate adjacent a light-incident upper surface of the image sensor. An optical isolation grid surrounds each photodiode structure and defines the pixel boundary. The optical isolation grid extends to a depth of at least the thickness of the photodiode structure and prevents incident light from penetrating through the incident pixel to an adjacent pixel. A positive diffusion plug vertically extends through a portion of the photodiode structure. A negative diffusion plug vertically extends into the semiconductor substrate for transferring charge generated in the photodiode to a charge collecting region within the semiconductor substrate. Pixel circuitry positioned beneath the photodiode controls charge transfer to image readout circuitry.

    摘要: A multilayer microelectronic device package includes one or more vertical electrical contacts. At least one semiconductor material layer is provided having one or more electrical devices fabricated therein. An electrical contact pad can be formed on or in the semiconductor material layer. Another material layer is positioned adjacent to the semiconductor material layer and includes a conductive material stud embedded in or bonded to the layer. A via is formed through at least a portion of the semiconductor material layer and the electrical contact pad and into the adjacent layer conducting material stud. The via is constructed such that the via tip terminates within the conducting material stud, exposing the conducting material. A metallization layer is disposed in the via such that the metallization layer contacts both the electrical contact pad and the conducting material stud exposed by the via tip.
