The invention provides a system and method for vaporizing a target structure on a substrate. According to one or more aspects, a user command to send an electronic message using a mobile computing device may be detected. The geospatial texture data may advantageously be retrieved and displayed in successive additive layers of resolution. A set of values may be estimated for the N parameters from data in one or more of the images. The polish pad may have asperities having a width greater than a width of metal line features of the wafer.
