Abstract: The implementations described herein generally relate to 30 nm in-line liquid particle count testing equipment which analyses and cleans semiconductor processing equipment. More specifically, the implementations described relate to a system for diluting, analyzing, and modifying fluids to enable the observation of the contents of the fluids. A dilution sampling tool is coupled with a liquid particle detector for reading the contents of an extraction solution containing particles from semiconductor processing equipment, such as a liner, a shield, a faceplate, or a showerhead, in a cleaning tank. As such, accurate liquid particle readings may be had which reduce oversaturation of the particle detector.

Abstract: Embodiments of the present invention provide a polishing ring assembly suitable for polishing an electrostatic chuck and method of using the same. In one embodiment, the polishing ring assembly has a retaining ring assembly and an electrostatic chuck fixture. The retaining ring assembly includes an inner diameter and a top surface, a plurality of outer drive rings wherein the plurality of outer drive rings are placed on the top surface of the ceramic retaining ring. The electrostatic chuck fixture includes an electrostatic chuck drive plate adjacent to the inner diameter of in the ceramic retaining ring. The electrostatic chuck drive plate has a lock to secure retaining ring assembly with the electrostatic chuck fixture without transferring the weight from one assembly over to the other through the locking mechanism.

Abstract: A processing chamber component and method for fabricating the same are provided. The processing chamber component is fabricated in the manner described herein and includes the creation of at least a macro texture on a surface of the chamber component. The macro texture is defined by a plurality of engineered features arranged in a predefined orientation on the surface of the chamber component. In some embodiments, the engineered features prevent formation of a line of sight surface defined between the features to enhance retention of films deposited on the chamber component.
