  • Patent number: 11897761
    Abstract: 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.

  • Patent number: 8828802
    Abstract: A wafer level chip scale package includes a first dielectric layer having a first surface, a second surface, and a main through hole passing through the first dielectric layer between the first and second surfaces. A semiconductor die is disposed in the main through hole of the first dielectric layer and including a bond pad disposed away from the first surface of the first dielectric layer. A redistribution layer is electrically connected to the bond pad of the semiconductor die and extends along the second surface of the first dielectric layer. A second dielectric layer covers the first dielectric layer and the redistribution layer and has an opening exposing the redistribution layer. An under bump metal fills the opening of the second dielectric layer and is electrically connected to the redistribution layer. A solder ball is electrically connected to the under bump metal.
