Abstract
A system and method for blocking light from regions around a photodiode in a pixel of an image sensor is provided. In an embodiment a first optical block layer is formed on a first glue layer and a second glue layer is formed on the first optical block layer. The formation of the first optical block layer and the second glue layer is repeated one or more times to form multiple optical block layers and multiple glue layers. As such, if voids open up in the optical block layers during further processing, there is another optical block layer to block any light that may have penetrated through the void.
