Abstract
An image sensor includes an optical sensor region, a stack of dielectric and metal layers, and an embedded layer. The optical sensor is disposed within a semiconductor substrate. The stack of dielectric and metal layers are disposed on the front side of the semiconductor substrate above the optical sensor region. The embedded focusing layer is disposed on the backside of the semiconductor substrate in a Backside Illuminated (BSI) image sensor, supported by a support grid, or a support grid composed of the semiconductor substrate.
