  • Patent number: 7662712
    Abstract: A method for fabricating a semiconductor device includes providing a semiconductor substrate comprising a patterned metal conductor layer. To provide UV blocking, an overlying separation layer is formed over the substrate, and a UV blocking layer of silicon enriched oxide is formed over the separation layer. The UV blocking layer has a silicon atomic concentration sufficient for ultraviolet blocking. A gap-filling, hydrogen-blocking layer may be formed over the semiconductor substrate, and any the UV blocking layer, to prevent hydrogen from passing therethrough.

  • Publication number: 20080088827
    Abstract: A method of monitoring a plasma process tool is provided, which includes obtaining a spectrum of a film to be detected from the plasma process tool, and then analyzing the spectrum by integrating a function of the spectrum intensity which focuses on specific or desired wavelength range, thereby determining whether the spectrum is abnormal from a obtained value. Since the film to be detected is detected after depositing the film in the plasma process tool, and therefore the film with a desired quality may be obtained.
