    Abstract: Endpoint of a chemical mechanical polishing process is detected by monitoring acoustical emissions produced by contact between a polishing pad and a wafer. The acoustic information is resolved into a frequency spectrum utilizing techniques such as fast Fourier transformation. Characteristic changes in frequency spectra of the acoustic emissions reveal transition in polishing between different material layers. CMP endpoint indicated by a change in the acoustic frequency spectrum is validated by correlation with other sensed properties, including but not limited to time-based changes in amplitude of acoustic emissions, frictional coefficient, capacitance, and/or resistance. CMP endpoint revealed by a change in acoustic frequency spectrum can also be validated by comparison with characteristic frequency spectra obtained at endpoints or polishing transitions of prior operational runs.

    Abstract: Resistance to corrosion in a plasma environment is imparted to components of a semiconductor processing tool by forming a rare earth-containing coating over component surfaces. The plasma-resistant coating may be formed by sputtering rare earth-containing material onto a parent material surface. Subsequent reaction between these deposited materials and the plasma environment creates a plasma-resistant coating. The coating may adhere to the parent material through an intervening adhesion layer, such as a graded subsurface rare earth layer resulting from acceleration of rare earth ions toward the parent material at changed energies prior to formation of the coating.
