Abstract: A polishing article has a polishing surface and an aperture, the aperture including a first section and a second section. The polishing article includes a projection extending inwardly into the aperture. The polishing article includes a lower portion on a side of the first surface farther from the polishing surface. A window has a first portion positioned in the first section of the aperture and a second portion extending into the second section of the aperture. The window has a second surface substantially parallel to the polishing surface. A first adhesive adheres the first surface of the projection to the second surface of the window to secure the window to the projection and a second adhesive of different material composition than the first adhesive. The second adhesive is positioned laterally between the second portion of the window and the lower portion of the polishing article.

Abstract: The implementations described herein generally relate to a sensing device for use in the semiconducting industry, which sense process parameters to control semiconductor processes. More specifically, the implementations relate to packaging for a surface acoustic wave (SAW) based devices or wireless or RF-responsive sensors for use in the harsh processing environments of a semiconductor processing chamber such that the neither the sensor and its components nor the chamber components interfere with or contaminate one another. The sensor packaging may include various packaging layers with or without protective coatings and a waveguide. The packaging may have a thickness chosen such that the thickness is less than the electromagnetic wavelength of a SAW sensor radio wave. The sensing devices may be disposed in cavities of the chamber, the processing volume, on chamber components, and/or on the substrate.
