  • Publication number: 20090184325
    Abstract: A method of planarizing a substrate. An organic layer is formed on a base substrate to cover a metal line formed on the base substrate. A portion of the organic layer is removed to form a pre-planarization layer exposing the metal layer, so that a surface of the base substrate having the metal line is planarized. The pre-planarization layer is cured to flow toward a side surface of the metal line to form a planarization layer making contact with the side surface of the metal line. Therefore, a stepped portion between the base substrate and the metal line can be minimized or substantially eliminated, thereby increasing the surface uniformity of a subsequent layer, thereby improving the reliability of the manufacturing process.

  • Publication number: 20080126390
    Abstract: A method for efficiently stress testing a service oriented architecture based application. A business process flow is recorded between a client and a server. When an XML document is extracted from the recorded business process flow, an XML document file is created for the extracted XML document, an XML document descriptor file is created comprising XPath queries for data elements in the XML document file, a configuration file is created comprising user input parameters obtained from the recorded business process flow, and test input data file is created. The user input parameters in the configuration file are used to generate a test script to test the service oriented architecture based application, wherein data values from the test input data file are inserted into a template of the XML document file at locations specified by the XPath queries in the XML document descriptor file. The test script is then executed.
