  • Patent number: 9583558
    Abstract: A microelectronic device contains a high voltage component having a high voltage node and a low voltage node. The high voltage node is isolated from the low voltage node by a main dielectric between the high voltage node and low voltage elements at a surface of the substrate of the microelectronic device. A lower-bandgap dielectric layer is disposed between the high voltage node and the main dielectric. The lower-bandgap dielectric layer contains at least one sub-layer with a bandgap energy less than a bandgap energy of the main dielectric. The lower-bandgap dielectric layer extends beyond the high voltage node continuously around the high voltage node. The lower-bandgap dielectric layer has an isolation break surrounding the high voltage node at a distance of at least twice the thickness of the lower-bandgap dielectric layer from the high voltage node.

  • Publication number: 20150110564
    Abstract: The invention relates to structures, such as offshore structures, associated apparatus and methods. For example, the invention can relate to wind turbine structures, such as piles for offshore wind turbines, and associated apparatus and methods. In some examples, the invention relates to guide apparatus for offshore piles having a guide portion configured to provide an acoustic barrier between a pile and a surrounding body of water during deployment of a pile at a body of water. The apparatus may comprise a dampening structure, such as inflatable bladders, or the like, configured to provide the acoustic barrier. In some example, the guide apparatus comprises a piling template, configured to be positioned on a water floor, so that the guide portion can locate, and be positioned with, the template to allow for guiding of a pile to a water floor.

  • Patent number: 8815642
    Abstract: A method of forming stacked die devices includes attaching first semiconductor die onto a wafer to form a reconstituted wafer, and then bonding second semiconductor die onto the first semiconductor die to form a plurality of singulated stacked die devices on the wafer. A support tape is attached to a bottomside of the second semiconductor die. A dicing tape is attached to the wafer. The wafer is laser irradiated before or after attachment of the dicing tape at intended dicing lanes that align with gaps between the first semiconductor die to mechanically weaken the wafer at the intended dicing lanes, but not cut through the wafer. The dicing tape is pulled to cleave the wafer into a plurality of singulated portions to form a plurality of singulated stacked die devices attached to the singulated wafer portions by the dicing tape. The support tape is removed prior to cleaving.
