  • Publication number: 20170098024
    Abstract: A processor-implemented method is provided for placing and routing a circuit design. A first netlist is generated for the circuit design. Placement is performed for the first netlist on a target programmable integrated circuit (IC) to produce a first placed design. A set of optimizations are performed on the first placed design. The set of optimizations are recorded in an optimization history file. One or more optimizations specified in the optimization history file are performed on the first netlist to produce a second netlist that is different than the first netlist. Placement is performed for the second netlist on the target programmable IC to produce a second placed design that is different than the first placed design. Nets of the second placed design are routed to produce a placed and routed circuit design.

  • Publication number: 20170011957
    Abstract: Provided is an intermetallic dielectric layer structure of a silicon-on-insulator device, comprising a silicon-rich oxide layer (54) covering a metal interconnect, a fluorine-silicon glass layer on the silicon-rich oxide layer, and a non-doped silicate glass layer on the fluorine-silicon glass layer; the thickness of the silicon-rich oxide layer (54) is 700 angstroms ±10%; the silicon-rich oxide layer having a greater thickness captures movable ions on an unsaturated bond, such that it is difficult for the movable ions to pass through the silicon-rich oxide layer, thus blocking the movable ions. The present invention has good performance in an integrity evaluation of the gate oxide layer, and avoids damage to the device caused by the aggregation of movable ions at an interface. Also provided are a silicon-on-insulator device and a method of manufacturing the intermetallic dielectric layer of the silicon-on-insulator device.

  • Patent number: 9524692
    Abstract: A signal correcting method and a signal correcting device. The signal correcting method includes sampling a signal to be corrected at different sampling times, and comparing a signal value at each of the sampling times in one signal period with a preset signal value corresponding to the sampling time. When the signal value at the sampling time is equal to the corresponding preset signal value, the signal value at the sampling time is kept unchanged. When the signal value at the sampling time is not equal to the corresponding preset signal value, the signal value at the sampling time is corrected to be the preset signal value corresponding to the sampling time.

  • Publication number: 20160272892
    Abstract: This disclosure provides high-efficiency and low-energy-consumption synthetic methods of a series of phosphorus-nitrogen-based intumescent flame retardants and the use thereof in paint flame retarding. 1 part by weight of a phosphorization agent and 0.5-4.0 parts by weight of a nitrogen-containing foaming agent are uniformly mixed and stirred at room temperature, and an amount of water is further added to emit heat and initiate reaction. 0.5-3.0 parts by weight of a charring agent and 0.5-4.0 parts by weight of a hydroxy-containing polyfuctional crosslinking agent are then added, and reacted with stirring. An amine compound is finally added for neutralization until pH value is 5-8, and solid liquid separation is performed. The solid portion is dried to obtain a main body portion of a phosphorus-nitrogen-based intumescent flame retardant. The resultant filtrate is diluted with 1/3-2/3 volume of water, and a flame retardant product is obtained.

  • Publication number: 20160245758
    Abstract: Embodiments include devices, systems and processes for using a white light interferometer (WLI) microscope with a tilted objective lens to perform in-line monitoring of both resist footing defects and conductive trace undercut defects. The defects may be detected at the interface between dry film resist (DFR) footings and conductive trace footing found on insulating layer top surfaces of a packaging substrate. Such footing and undercut defects may other wise be considered “hidden defects”. Using the WLI microscope with a tilted objective lens provides a high-throughput and low cost metrology and tool for non-destructive, non-contact, in-line monitoring.
