Abstract
Provided is an image sensor device. The image sensor device includes a device substrate having a front side and a back side. The device substrate has a radiation-sensing region that can sense radiation that has a corresponding wavelength. The image sensor also includes a first layer formed over the front side of the device substrate. The first layer has a first refractive index and a first thickness that is a function of the first refractive index. The image sensor also has a second layer formed over the first layer. The second layer is different from the first layer and has a second refractive index and a second thickness that is a function of the second refractive index.
