    摘要: A portion of a conductive layer (310, 910) provides a capacitor electrode (310.0, 910.0). Dielectric trenches (410, 414, 510) are formed in the conductive layer to insulate the capacitor electrode from those portions of the conductive layer which are used for conductive paths passing through the electrode but insulated from the electrode. Capacitor dielectric (320) can be formed by anodizing tantalum while a nickel layer (314) protects an underlying copper (310) from the anodizing solution. This protection allows the tantalum layer to be made thin to obtain large capacitance. Chemical mechanical polishing of a layer (610) is made faster, and hence possibly less expensive, by first patterning the layer photolithographically to form, and/or increase in height, upward protrusions of this layer.

    摘要: A hybrid integration process for fabrication of an optical cross-connect switching apparatus. The switching element is based on the deflection of light beam in electro-optic materials by applying electric field across electrodes of an appropriate configuration. The integration process includes fabrication of a substrate (e.g. silicon substrate) with 2D imaging optics from polymeric materials (or silica), fabrication of the light deflecting element, and assembly of the deflecting element on the substrate with imaging optics. The fabrication of the light deflecting element includes fabrication of a LN (lithium niobate) block. The LN block assembled in an optical switching apparatus includes a two-dimensional waveguide formed on a surface of the LN block and an electrode on a surface of the LN block.
