    Abstract: According to various aspects and embodiments, a support structure for packaging an electronic device is provided. In one example, a packaged electronic device includes a substrate, at least one electronic device disposed on the substrate, an encapsulation structure disposed on the substrate and having a wall that forms a perimeter around the at least one electronic device, and at least one support structure formed from a photosensitive polymer and disposed adjacent the wall of the encapsulation structure. The at least one support structure has a configuration that provides at least one of increased adhesion and mechanical strength to the encapsulation structure.

    Abstract: Disclosed are systems and methods for improving front-side process uniformity by back-side metallization. In some implementations, a metal layer can be formed on the back side of a semiconductor wafer prior to certain process steps such as plasma-based processes. Presence of such a back-side metal layer reduces variations in, for example, thickness of a deposited and/or etched layer resulting from the plasma-based processes. Such reduction in thickness variations can result from reduced variation in radio-frequency (RF) coupling during the plasma-based processes. Various examples of wafer types, back-side metal layer configurations, and plasma-based processes are disclosed.
