Abstract
A system and method for reducing cross-talk between photosensitive diodes is provided. In an embodiment an isolation region comprising a first concentration of dopants is located between the photosensitive diodes. The photosensitive diodes have a second concentration of dopants that is less than the first concentration of dopants, which helps to prevent diffusion from the photosensitive diodes to form a potential path for undesired cross-talk between the photosensitive diodes.
