    摘要: The present invention provides a structure of package comprising a substrate with a die receiving cavity formed within an upper layer of the substrate, wherein terminal pads are formed on the upper surface of the substrate, the same plain as the micro lens. A die is disposed within the die receiving cavity by adhesion and a dielectric layer formed on the die and the substrate. A re-distribution metal layer (RDL) is formed on the dielectric layer and coupled to the die. An opening is formed within the dielectric layer and a top protection layer to expose the micro lens area of the die for Image Sensor chip. A protection layer (film) be coated on the micro lens area with water repellent and oil repellent to away the particle contamination. A transparent cover with coated IR filter is optionally formed over the micron lens area for protection.
