  • Publication number: 20050170578
    Abstract: Nonvolatile memory wordlines (160) are formed as sidewall spacers on sidewalls of control gate structures (280). Each control gate structure may contain floating and control gates (120, 140), or some other elements. Pedestals (340) are formed adjacent to the control gate structures before the conductive layer (160) for the wordlines is deposited. The pedestals will facilitate formation of the contact openings (330.1) that will be etched in an overlying dielectric (310) to form contacts to the wordlines. The pedestals can be dummy structures. A pedestal can physically contact two wordlines.

  • Patent number: 6909403
    Abstract: A collinear antenna segment is provided with a plurality of radiating elements and inter-element phasing sections arranged alternately on a singlesided elongated substrate. The segment has an operatively curved in-use configuration about a longitudinal axis running substantially along the length of the segment. In use, the inter-element phasing sections allow the radiating elements to radiate electromagnetic radiation substantially in phase over an intended range of frequencies. The segment may be arranged on a flexible substrate which can be operatively curved for insertion into a radome. Alternatively, the segment may be directly arranged on the curved inner surface of a radome.

  • Publication number: 20050124102
    Abstract: Substrate isolation trench (224) are formed in a semiconductor substrate (120). Dopant (e.g. boron) is implanted into the trench sidewalls by ion implantation to suppress the current leakage along the sidewalls. During the ion implantation, the transistor gate dielectric (520) faces the ion stream, but damage to the gate dielectric is annealed in subsequent thermal steps. In some embodiments, the dopant implantation is an angled implant. The implant is performed from the opposite sides of the wafer, and thus from the opposite sides of each active area. Each active area includes a region implanted from one side and a region implanted from the opposite side. The two regions overlap to facilitate threshold voltage adjustment.

  • Publication number: 20020041413
    Abstract: A fiberoptic network with an optical supervisory channel in each of the optical fibers interconnecting the nodes of the network is described. Together with IP routers, the optical supervisory channels form a control network over which signaling and control signals are exchanged by which provisioning and restoration operations are performed at each node. To restore connections between the nodes upon a failure of the network, the control network helps to maintain at each node a synchronized database of network connections between the nodes, send messages to other nodes to initiate restoration operations by a node noticing the failure; and recalculate network connections around the failure by each node from a synchronized database at the node.
