An infrastructure delivery platform provides a proxy service as an enhancement to the TLS/SSL protocol to off-load to an external server the generation of a digital signature, the digital signature being generated using a private key that would otherwise have to be maintained on a terminating server.

In this manner, a private key used to generate the digital signature (or, more generally, to facilitate the key exchange) does not need to be stored in association with the terminating server. Rather, that private key is stored only at the external server, and there is no requirement for the pre-master secret to travel (on the wire). |

Lookthrough compression arrangement
An apparatus and process for pumping laser media by an optical pump over a 10 nanosecond period and thereafter time compressing the energy into an extraction pulse and focusing onto a target with a final 1 nanosecond irradiation time are disclosed. The exciting pump pulses are directed into a lookthrough compression arrangement wherein they energize a stimulated scattering process in low pressure (about 1 atmosphere) gaseous media and impinge in an off axis backward geometry. The extraction pulse is formed and directed towards the target with the appropriate information (color, phase, desired irradiance pattern) impressed on it at relatively low energy by manipulation with conventional, solid material optical elements. Once formed, it traverses the gaseous media, is amplified, and proceeds through a vacuum transition section and onto the target. After the injection of the extraction pulse into the lookthrough compression arrangement, it is amplified in the gaseous media by conversion of the pump energy, coupled through the scattering process. The media and the pump and extraction pulses are tailored to give high energy gain to the input optical pulse, high output fluence, good beam quality (high fidelity amplification to the desired temporal and spatial shape), and time compression. Once injected into the entrance to the first section by the material elements, the extraction pulse proceeds through shutter areas that separate different media regions and encounter no further solid material optical elements as it travels to the target. The focus on the target is impressed before amplification and time compression from the pump pulses and results in a very high brightness irradiance of the target. The desired spatial pattern of irradiance on the target is likewise formed with material elements and then imaged onto the target. Fluences some 2-3 orders of magnitude above those available under the conventional art may be thus obtained with an output brightness better by some six orders of magnitude. |

Short pulse wavelength tuning via timed soliton-dispersive wave interaction
When a soliton and a dispersive pulse propagate in an optical fiber, they can interact via cross-phase modulation, which occurs when one pulse modulates the refractive index experienced by the other pulse. Cross-phase modulation causes each pulse to shift in wavelength by an amount proportional to the time delay between the pulses. Changing the time delay between the pulses changes the wavelength shift of each pulse. This make it possible to produce pulses whose output wavelengths can be tuned over large ranges, e.g. hundreds of nm, in a time as short as the pulse repetition period of the laser (e.g., at rates of megahertz or gigahertz). Such a laser requires no moving parts, providing high reliability. The laser's optical path can be made entirely of optical fiber, providing high efficiency with low size, weight, and power consumption. |

High temperature tubular heaters
A heater assembly includes a heating member, a mounting member that mounts the heating member to a wall of an external component, and an insulator disposed between the heating member and the wall. The insulator electrically insulates the heating member from the wall and blocks a ground path from the heating member to the wall of the external component. |

Semiconductor device
To suppress a change in electrical characteristics and to improve reliability in a semiconductor device using a transistor including an oxide semiconductor. The semiconductor device includes a gate electrode over an insulating surface, an oxide semiconductor film overlapping with the gate electrode, a gate insulating film which is between the gate electrode and the oxide semiconductor film and is in contact with a surface of the oxide semiconductor film, a protective film in contact with an opposite surface of the surface of the oxide semiconductor film, and a pair of electrodes in contact with the oxide semiconductor film. In the gate insulating film or the protective film, the amount of gas having a mass-to-charge ratio m/z of 17 released by heat treatment is greater than the amount of nitrogen oxide released by heat treatment. |

Features for improving process uniformity in a millisecond anneal system
Systems and methods for improving process uniformity in a millisecond anneal system are provided. In some implementations, a process for thermally treating a substrate in a millisecond anneal system can include obtaining data indicative of a temperature profile associated with one or more substrates during processing in a millisecond anneal system. The process can include one or more of (1) changing the pressure inside the processing chamber of the millisecond anneal system; (2) manipulating the irradiation distribution by way of the refracting effect of a water window in the millisecond anneal system; (3) adjusting the angular positioning of the substrate; and/or (4) configuring the shape of the reflectors used in the millisecond anneal system. |

Etching method
A method for etching a ruthenium film includes a first step of etching the ruthenium film by plasma processing using oxygen-containing gas, and a second step of etching the ruthenium film by plasma processing using chlorine-containing gas. The first step and the second step are alternately performed. In the first step and the second step, the ruthenium film is etched at a target control temperature for a target processing time that are determined based on a pre-obtained relation between an etching amount per one cycle including the first step and the second step as a set, a control temperature of the ruthenium film, and processing times of each of the first step and the second step. |

Hybrid double patterning method for semiconductor manufacture
A method of fabricating an integrated circuit (IC) uses a first lithography technique having a first resolution and a second lithography technique having a second resolution lower than the first resolution. The method includes deriving a graph from an IC layout, the graph having vertices and edges that connect some of the vertices, the vertices representing IC patterns in the IC layout, the edges representing spacing between the IC patterns that are smaller than the second resolution. The method further includes classifying the edges into at least two types, a first type of edges representing spacing that is smaller than the first resolution, a second type of edges representing spacing that is equal to or greater than the first resolution but smaller than the second resolution. |
