    Abstract: Embodiments of a method for thinning a wafer are provided. The method includes placing a wafer on a support assembly and securing an etching mask to a backside of the wafer. The etching mask covers a peripheral portion of the wafer. The method further includes performing a wet etching process on the backside of the wafer to form a thinned wafer, and the thinned wafer includes peripheral portions having a first thickness and a central portion having a second thickness smaller than the first thickness. Embodiments of system for forming the thinned wafer are also provided.
