Abstract
A camera module and a photosensitive assembly thereof, an electronic device, and a manufacturing method are provided. The photosensitive assembly includes a photosensitive chip having a photosensitive area and an electric connection area located around the photosensitive area, at least one resistance-capacitance device, a conducting element, an expanded wiring layer, and a molded base. The expanded wiring layer has a top surface and a bottom surface. The at least one resistance-capacitance device is electrically connected to the bottom surface of the expanded wiring layer. The conducting element extends between the bottom surface of the expanded wiring layer and the electric connection area of the photosensitive chip, so as to electrically connect the photosensitive chip to the expanded wiring layer by means of the conducting element. A light hole is formed in the expanded wiring layer, and the light hole corresponds to at least the photosensitive area of the photosensitive chip. The molded base is integrally combined with the photosensitive chip, the at least one resistance-capacitance device, and the expanded wiring layer.
