Abstract:
1. A fabrication method of a structure of a package for a semiconductor image pickup device, comprising the steps of: forming an insulating film on the surface of a semiconductor image pickup device and then selectively etching the insulating film so as to expose electrode pads formed on the edges of the semiconductor image pickup device; forming at least one functional polymer layer on an image sensing unit formed at the center of the semiconductor image pickup device; forming at least one metal thin film layer on the top part of the resultant material while adjusting the surface temperature of the semiconductor image pickup device at the range between a room temperature and 200° C.; forming a photosensitive film on the top part of the metal thin film layer and then light-exposing and developing the same so as to expose the metal thin film layer of the regions where the electrode pads of the semiconductor image pickup device are formed; forming a bump on the top part of the metal thin film layer exposed to the regions where the electrode pads of the semiconductor image pickup device are formed; and removing the photosensitive film and then etching the metal thin film layer using the bump as a mask.
