Abstract
An image sensor includes a semiconductor material including a photodiode disposed in the semiconductor material and an insulating material. A surface of the semiconductor material is disposed between the insulating material and the photodiode. The image sensor also includes isolation structures disposed in the semiconductor material and in the insulating material, and the isolation structures extend from within the semiconductor material through the surface and into the insulating material. The isolation structures include a core material and a liner material. The liner material is disposed between the core material and the semiconductor material, and is also disposed between the insulating material and the core material.
