Abstract:
An image sensor includes a photo diode formed over a semiconductor substrate. At least one IMD layer is formed on the semiconductor substrate. A dielectric medium fills a through-hole formed in the IMD layer over the photo diode. The dielectric medium may be made with materials with a higher refractive index than the materials forming the IMD layer.
