A package structure and a method for manufacturing the same are disclosed. The package structure includes a first plastic body which covers a first light sensor and a light emitter, and a second plastic body which is made of infrared cutoff materials and fills inner pins of a lead frame or is formed below the lead frame. A trench is formed in the first plastic body so that a light-blocking layer is located on a side surface of the first plastic body. The second plastic body and the light-blocking layer are used to avoid influence of infrared light on a first light sensor.

Package structure of light emitter and light sensor with light-blocking layer and method for manufacturing the same

In one embodiment, a chip package assembly can include: a first substrate at a bottom layer, the first substrate having a first surface and a second surface opposite to the first surface, where the second surface is provided with a first group of inner leads; at least one chip layer above the first group of inner leads, where each of the chip layers comprises a third surface and a fourth surface opposite to the third surface, where electrodes on the third surface that that lie at the lowest level are electrically coupled to the first group of inner leads through a first connector; and a second substrate above the fourth surface on the topmost layer and having a fifth surface, and where the fifth surface is provided with a second group of inner leads electrically coupled to the electrodes on the fourth surface on the topmost layer.
