The invention provides a method of reducing the roughness of the free surface of a wafer of semiconductor material by applying a rapid thermal annealing process under a pure argon atmosphere for a time sufficient to uniformly heat and smooth the free surface of the wafer. The group initially selects N issues from the universe of potential issues and often assigns the issues images and titles. The cargo ships are moored between quays of a terminal building constructed in or adjacent to a waterway. To provide greater insight and to assess the overall efficacy of the web presence optimization effort, historical search rank data can be correlated with specific events and reported to a user. The aperture of the stop has an asymmetrical feature that facilitates operation on specular targets.
