    摘要: A method of fabricating an image sensor includes forming a photoelectric transformation device on a substrate and forming a dielectric layer structure on the substrate. The dielectric layer structure includes multi-layer interlayer dielectric layers and multi-layer metal interconnections which are located between the multi-layer interlayer dielectric layers. A cavity which penetrates the multi-layer interlayer dielectric layers on the photoelectric transformation device is formed. A heat treatment is performed on the substrate on which the cavity is formed.
