摘要：
An image sensor package may include a semiconductor wafer having a pixel array, a color filter array (CFA) formed over the pixel array, and one or more lenses formed over the CFA. A light block layer may couple over the semiconductor wafer around a perimeter of the lenses and an encapsulation layer may be coupled around the perimeter of the lenses and over the light block layer. The light block layer may form an opening providing access to the lenses. A mold compound layer may be coupled over the encapsulation layer and the light block layer. A temporary protection layer may be used to protect the one or more lenses from contamination during application of the mold compound and/or during processes occurring outside of a cleanroom environment.
