Abstract
Provided is an image sensor device. The image sensor device includes a substrate having a front side and a back side. The image sensor also includes a radiation-detection device that is formed in the substrate. The radiation-detection device is operable to detect a radiation wave that enters the substrate through the back side. The image sensor further includes a recrystallized silicon layer. The recrystallized silicon layer is formed on the back side of the substrate. The recrystallized silicon layer has different photoluminescence intensity than the substrate.
