In one example, an electronic device includes a semiconductor sensor device having a cavity extending partially inward from one surface to provide a diaphragm adjacent an opposite surface. A barrier is disposed adjacent to the one surface and extends across the cavity, the barrier has membrane with a barrier body and first barrier strands bounded by the barrier body to define first through-holes. The electronic device further comprises one or more of a protrusion pattern disposed adjacent to the barrier structure, which can include a plurality of protrusion portions separated by a plurality of recess portions; one or more conformal membrane layers disposed over the first barrier strands; or second barrier strands disposed on and at least partially overlapping the first barrier strands. The second barrier strands define second through-holes laterally offset from the first through-holes. Other examples and related methods are also disclosed herein.
