Abstract:
1. A semiconductor device assembly comprising: a semiconductor substrate having a back surface, an active surface comprising an array of optically interactive semiconductor devices thereon, and an array of microlenses, at least one microlens of the array of microlenses being disposed over at least one optically interactive semiconductor device of the array of optically interactive semiconductor devices; at least one via extending from the active surface to the back surface adjacent a periphery of the array of optically interactive semiconductor devices, the at least one via having an electrically conductive material disposed therein and in electrical communication with the at least one optically interactive semiconductor device of the array of optically interactive semiconductor devices; and at least one redistribution line extending over at least an entire cross-section of the at least one via, the at least one redistribution line in electrical communication with the electrically conductive material in the at least one via.
