Abstract
One or more embodiments are directed to ambient light sensor packages, and methods of making ambient light sensor packages. One embodiment is directed to an ambient light sensor package that includes an ambient light sensor die having opposing first and second surfaces, a light sensor on the first surface of the ambient light sensor die, one or more conductive bumps on the second surface of the ambient light sensor die, and a light shielding layer on at least the first surface and the second surface of the ambient light sensor die. The light shielding layer defines an opening over the light sensor. The ambient light sensor package may further include a transparent cover between the first surface of the ambient light sensor die and the light shielding layer, and an adhesive that secures the transparent cover to the ambient light sensor die.
