Abstract: This invention describes methods of polishing with pads useful in the manufacture of semiconductor devices or the like. These pads have an advantageous hydrophilic polishing material and have an innovative surface topography and texture which generally improves predictability and polishing performance. These pads provide exceptional performance when used for polishing in conjunction with a slurry in which the abrasive particles are stabilized by use of an amino alcohol. They are also useful when used with slurries comprising an organic polymer.
