Abstract: In one embodiment of the disclosure, a method includes providing a carrier substrate, forming a first region over an upper surface of the substrate, creating an electrical component using a planar process, embedding the electrical component in the dielectric layer, and removing a substrate portion of the electrical component. The first region includes a dielectric layer and may be made of any material that electrically isolates the electrical component from the carrier substrate. The electrical component may be created using a planar process thereby having an epitaxial surface that is embedded in the dielectric layer.

Abstract: A method for forming an integrated circuit includes transforming at least a portion of a first substrate layer to form a conductive region within the first substrate layer. An integrated circuit device is provided proximate an outer surface of the first substrate layer. The integrated circuit device transmits or receives electrical signals through the conductive region. A second substrate layer is disposed proximate to the outer surface of the first substrate layer to enclose the integrated circuit device in a hermetic environment.

Abstract: Methods and apparatus for local oscillator generation are provided. In a method embodiment, a method of signal processing includes splitting a signal having a first frequency into at least a first portion and a second portion. The method also includes generating a second signal having a second frequency at a predetermined frequency difference from the first frequency by optically modulating the first portion. In addition, the method includes generating a third signal having a frequency component at a frequency that is approximately the same as the predetermined frequency difference from the first frequency by combining the second portion with the second signal.

Abstract: According to one embodiment of the invention, a method for sealing one or more vias comprises providing a first substrate having vias, forming an adhesion layer on an inner surface of the vias, sandwiching a solder layer between the first substrate and a second substrate, and elevating of the first substrate, second substrate, and solder layer to a temperature above a eutectic point and below a melting point of the solder layer. The act of elevating the solder layer to a temperature above the eutectic point and below the melting point causes the solder layer to flow into the vias in a generally consistent manner.

Abstract: A polarizing filter includes a portion with a filtering layer having a plurality of openings extending therethrough, where this portion has a maximum physical thickness in a radiation travel direction which is less than approximately one wavelength of the radiation being filtered. A method of making the filter includes: forming a filtering layer over a substrate; creating a plurality of openings through a portion of the filtering layer; and separating the filtering layer from the substrate.
