SHADOW RING KIT FOR PLASMA ETCH WAFER SINGULATION PROCESS
Last updated:
Abstract:
Shadow ring kits and methods of dicing semiconductor wafers are described. In an example, an etch apparatus includes a chamber, and a plasma source within or coupled to the chamber. An electrostatic chuck is within the chamber, the electrostatic chuck including a conductive pedestal to support a substrate carrier sized to support a wafer having a first diameter. A shadow ring assembly is between the plasma source and the electrostatic chuck, the shadow ring assembly sized to process a wafer having a second diameter smaller than the first diameter.
