An image pickup device and a manufacturing method thereof. A digital signal processing (DSP) chip is attached on a first surface of a substrate. A CMOS image sensor (CIS) chip is attached on an active surface of the DSP chip. The DSP chip and the CIS chip may be electrically connected to the substrate by wire bonding. A housing kit having a lens configured to transmit an image to the DSP chip may be mounted on the substrate. An inner space between the housing kit and the substrate is not molded, thereby simplifying a manufacturing process and providing a thinner and/or lighter image pickup device.

Image pickup device with non-molded DSP chip and manufacturing method

A wafer level chip package has a redistrubution substrate, at least one lower semiconductor chip stacked on the redisctribution substrate, and an uppermost semiconductor chip. The redistribution substrate has a redistribution layer and substrate pads connected to the redistribution layer. The lower semiconductor chip is stacked on the redistribution layer and may have through holes for partially exposing the redistribution layer, the through holes corresponding to the substrate pads, and having conductive filling material filling the through holes. The uppermost semiconductor chip may have the same elements as the lower semiconductor chip, and may be flip chip bonded to the through holes. The package may further have a filling layer for filling areas between chips, a metal lid for coating most of the external surfaces, and external connection terminals formed on and electrically connected to the exposed redistribution layer from the first dielectric layer of the redistribution substrate.
