Abstract: A wheel rim polishing tool simplifies the process of polishing tractor trailer wheel rims. The tool also reduces polishing time by polishing more surface area of the wheel rim per rotation as compared to what can be accomplished by hand or by means of a drill adapted with a polishing head. The tool further keeps the cost of polishing the wheel rims low by making a trip to a metal specialty shop no longer necessary. The wheel rim polishing tool is a portable device that allows the tractor trailer owner to polish their wheel rims quickly and easily.

Abstract: A method for controlling the residue clearing process of a chemical mechanical polishing (“CMP”) process is provided. Dynamic in-situ profile control (“ISPC”) is used to control polishing before residue clearing starts, and then a new polishing recipe is dynamically calculated for the clearing process. Several different methods are disclosed for calculating the clearing recipe. First, in certain implementations when feedback at T0 or T1 methods are used, a post polishing profile and feedback offsets are generated in ISPC software. Based on the polishing profile and feedback generated from ISPC before the start of the clearing process, a flat post profile after clearing is targeted. The estimated time for the clearing step may be based on the previously processed wafers (for example, a moving average of the previous endpoint times). The calculated pressures may be scaled to a lower (or higher) baseline pressure for a more uniform clearing.
