Abstract
An image sensor package includes an image sensor with a pixel array disposed in a semiconductor material, and a transparent shield adhered to the semiconductor material. The pixel array is disposed between the semiconductor material and the transparent shield. A light blocking layer is disposed in recessed regions of the transparent shield, and the recessed regions are disposed on an illuminated side of the transparent shield. The light blocking layer is disposed to prevent light from reflecting off edges of the transparent shield into the image sensor.
