WebMay 21, 2024 · The bevel etch process is used to remove any type of film on the edge of the wafer, whether it is a dielectric, metal, or organic material film. During this process, the wafer is held by a top and bottom plate so that the wafer edge is the only exposed part of the wafer (see Figure 2) [6]. This ensures that only the edge of the wafer is etched. Webdevice wafer. Depending on the application, the final device wafer thickness may be anywhere from about 10 μm to 150 μm. If the device wafer is thinner than 150 μm it is possible to process the thin wafer through various backside process steps if the thinned wafer is on a carrier wafer. There are several methods for accomplishing the temporary
