Abstract:
A method of fabricating an image sensor equipped with a lens, wherein a pixel array portion and a CMOS logic portion are integrated in one chip, the method comprising:forming a metal wire and depositing an insulating film and a top metallic layer on a substrate; remaining the top metallic layer around a pixel array and depositing protection films on the top metallic layer; exposing the top metallic layer between the protection films by carrying out a color filter formation process and then a masking process opening a pad metal terminal; depositing a titanium film and a metallic film onto the upper portion of the top metallic layer; opening a portion in which a metal convex portion is to be formed and forming the metal convex portion on the upper portion of the metallic film using an electroplating method; removing the metallic film and the titanium film around the metal convex portion; forming a lens to be aligned with the pixel array of a device; and coupling the device and the lens using alignment marks.
