  • Patent number: 10192779
    Abstract: Structures with altered crystallinity beneath semiconductor devices and methods associated with forming such structures. Trench isolation regions surround an active device region composed of a single-crystal semiconductor material. A non-single-crystal layer has a first section arranged beneath the trench isolation regions and a second section arranged beneath the active device region. The first section of the non-single-crystal layer has a first width in a vertical direction. The second section of the non-single-crystal layer has a second width in the vertical direction that is less than the first width of the first section of the non-single-crystal layer.

  • Patent number: 10109599
    Abstract: An integrated circuit (IC) structure is disclosed. The structure can include: an insulator positioned over a device layer; a capping layer positioned over the insulator; an inter-layer dielectric (ILD) positioned over the capping layer; a first metal wire positioned over the ILD, and outside an active area of the IC structure; a continuous metal crack stop in contact with, and interposed between, the first metal wire and the device layer, such that the continuous metal crack stop extends through at least the insulator, the capping layer, and the ILD; a second metal wire positioned over the ILD, and within the active area of the IC structure; and two vias vertically coupled to each other and interposed between the second metal wire and the device layer, such that the two vias extend through at least the insulator, the capping layer, and the ILD.

  • Patent number: 9750061
    Abstract: A system for communicating wireless signals between one or more sector controllers (SC) and one or more subscriber stations (SS) using different channels and different beams, wherein each of the one or more SS and the SC has a corresponding highly directional antenna; the one or more SC comprises a first SC; the one or more SS comprises a first SS; the first SS obtains network topology awareness (NTA) data from the first SC; the first SS selects a channel, a beam, and one of the one or more SC to establish an RF link based on the NTA data; and the first SS communicating with the selected SC using the established RF link.

  • Patent number: 9576899
    Abstract: Electrical fuses and methods for forming an electrical fuse. A semiconductor substrate is implanted to define a modified region in the semiconductor substrate. Trenches that surround the modified region and that penetrate into the semiconductor substrate to a depth greater than a depth of the modified region are formed in the modified region so as to define a fuse link of the electrical fuse. The substrate is removed from beneath the fuse link with a selective etching process that removes the semiconductor substrate with a first etch rate that is higher than a second etch rate of the modified region.

  • Patent number: 9444123
    Abstract: A battery pack includes a plurality of prismatic format batteries in a stacked configuration. Flexible graphite sheet heat spreaders are interposed between adjacent prismatic batteries in the stack. A heat sink extends the length of the stack of prismatic format batteries. Both heat spreader major surfaces contact the heat sink at contact areas and thereby extend into the heat sink by at least 30 percent of the thru-thickness of the heat sink.

  • Publication number: 20110020665
    Abstract: A surface finishing and coating methodology that provides a superior looking aluminum product with acceptable corrosion performance for outdoor use. In one embodiment, a coating of high purity aluminum is applied first to an aluminum article or product via cold or thermal spray and the mechanical surface modification (e.g., polishing, buffing, brushing, etc.) is clone second. The resulting product has the desirable light weight and mechanical properties of aluminum with the chosen look and performance of the high purity aluminum coating. The aluminum product to be coated may be obtained by extrusion, forging, casting, or rolling.
