The invention relates to the fabrication of integrated circuits in general, and notably the circuits of image sensors intended to form the electronic core of photographic apparatus or cameras. The chip is first aligned with respect to the package and then the package is aligned with respect to the optical system. The alignment of the chip with respect to the package is done optically. The alignment of the package with respect to the system is done mechanically with respect to the edges of the package. According to the invention, provision is made for optical marks to be provided on the package, these marks each having an edge aligned with a lateral edge of the package, so as to minimize the positioning errors which would be due to inaccurate positioning of the chip with respect to the edges of the package. |
