摘要:
Process solutions comprising one or more surfactants are used to reduce the number of defects in the manufacture of semiconductor devices. In certain embodiments, the process solution may reduce post-development defects such as pattern collapse or line width roughness when employed as a rinse solution either during or after the development of the patterned photoresist layer. Also disclosed is a method for reducing the number of defects such as pattern collapse and/or line width roughness on a plurality of photoresist coated substrates employing the process solution of the present invention.

A system and method for media adaptation are provided. A method for providing media to an electronic device includes receiving a request for a media with a set of characteristics, and determining if the media with the set of characteristics resides in a media storage. The method also includes if the media with the set of characteristics resides in the media storage, retrieving the media with the set of characteristics from the media storage. The method further includes if the media with the set of characteristics does not reside in the media storage, transcoding an alternate media with an alternate set of characteristics to produce a transcoded media with the set of characteristics. The method additionally includes providing the media with the set of characteristics from the media storage or the transcoded media with the set of characteristics to the electronic device.

A method and apparatus are provided for determining the quality of a speech transmission, including temporal clipping, delay and jitter, using a carefully constructed test signal (300) and digital signal processing techniques. The test signal that is to be transmitted through a speech transmission system (100) is created (700). Then the test signal is transmitted through the speech transmission system such that the speech transmission system creates an output signal that corresponds to the input signal, as modified by the speech transmission system (702). The test signal includes multiple segments (500) of speech signals interleaved with periods of silence. The periods of silence vary in duration according to a predefined pattern. Each segment of speech signals includes multiple predefined speech samples or symbols (400, 402, 404, 406, 408, 410, 412, 414) interleaved with a plurality of silence gaps. The speech samples have a common period of duration, but the silence gaps do not. The output signal from the speech transmission system is preferably recorded (704) and analyzed to determine its quality, including temporal clipping (706). This analysis preferably includes comparing the output signal with a reference signal derived from the test signal using a cross correlation function. A processor (114) coupled to memory (116) records and analyzes the output signal.

A method and apparatus for providing call admission control in a packet network such as an internet protocol (IP) network are provided. More particularly, a terminating endpoint of a logical connection on a packet network, e.g. an IP network, is provided with the ability to make a decision on whether to accept or reject an incoming call based on quality of service (QoS) indicator based on QoS metrics. These metrics indicate quality of service levels for specific logical connections and are accumulated over specified time periods.

A method and apparatus for backing up data in the source LUN is disclosed. The method for backing up the data in a source Logic Unit Number (LUN), includes: copying the data which needs to be modified in the source LUN to a resource pool; monitoring the resource utilization amount in the resource pool; creating a target LUN when the resource utilization amount exceeds a preset threshold; and copying the unmodified data in the source LUN and the backup data of the source LUN in the resource pool into the target LUN.
