Abstract:
A through-silicon via fabrication method includes etching a plurality of through holes in a silicon plate. An oxide liner is deposited on the surface of the silicon plate and on the sidewalls and bottom wall of the through holes. A metallic conductor is then deposited in the through holes. In another version, which may be used concurrently with the oxide liner, a silicon nitride passivation layer is deposited on the exposed back surface of the silicon plate of the substrate.
Abstract:
A method of forming a passivation layer comprising silicon nitride on features of a substrate is described. In a first stage of the deposition method, a dielectric deposition gas, comprising a silicon-containing gas and a nitrogen-containing gas, is introduced into the process zone and energized to deposit a silicon nitride layer. In a second stage, a treatment gas, having a different composition than that of the dielectric deposition gas, is introduced into the process zone and energized to treat the silicon nitride layer. The first and second stages can be performed a plurality of times.

The present invention is to provide a method and circuit for producing spread spectrum and over clock, which includes a primary circuit and a secondary circuit, wherein the primary circuit uses a frequency division technique based on phase swallow to achieve a high frequency resolution clock signal, and the secondary circuit multiplies the frequency of the output clock signal of the primary circuit, so as to expand its frequency range.
Abstract:
Ultrasonic sensors can be integrated and used to monitor composites throughout their production and during their useful lifetime. In an integrated program, ultrasonic sensors, in the illustrated embodiment contact sensors, can be used for quality control on raw rubber used for making a composite and for monitoring the cure of the rubber as it is transformed into a useful product, and non-contact sensors can be used to evaluate the product when it is completed, and to monitor its aging and wear during use. Such sensors can also be used in research to evaluate potential raw materials, and to compare cured candidate materials for properties useful in a completed product.

Abstract:
Systems and methods of transcoding video bitstreams that employ look-ahead approaches to enhance the overall perceptual quality of transcoded video information, communications, and entertainment delivered to an end user. The disclosed systems and methods of transcoding video bitstreams take into account the scene characteristics and the local coding complexity of video frames in a video sequence before performing bit allocations for the video frames, thereby significantly improving the perceptual quality of transcoded video delivered to the end user.

Abstract:
Systems and methods of measuring a temporal offset between audio content and video content that employ audio fingerprints from an audio signal in the audio content, and video fingerprints from video frames in the video content. The systems obtain reference audio and video fingerprints prior to transmission of video over a media channel, and obtain target audio and video fingerprints subsequent to transmission of the video over the media channel. Each fingerprint has an associated time stamp. Using the reference and target audio fingerprints and their associated time stamps, the systems determine an audio time stamp offset. Using the reference and target video fingerprints and their associated time stamps, the systems determine a video time stamp offset. Using the audio and video time stamp offsets, the systems determine a temporal offset between the video content and the audio content introduced by the media channel.
Abstract:
Systems and methods of objective video quality measurement that employ a reduced-reference approach to video quality measurement. Such systems and methods of objective video quality measurement can extract information pertaining to one or more features of a target video whose perceptual quality is to be measured, extract information pertaining to one or more features of a reference video, and employ one or more prediction functions involving the target features and the reference features to provide a measurement of the perceptual quality of the target video.
