Abstract:
A CCD-type solid-state pickup device comprising:a semiconductor substrate;a light-receiving section formed at the surface of said semiconductor substrate;a channel region formed at the surface of said semiconductor substrate separately from said light-receiving section;a first insulating film formed on said semiconductor substrate;a plurality of electric-charge transfer electrodes formed above said first insulating film above said channel region, said electric-charge transfer electrodes being arranged along the direction in which electric charges are transferred;a second insulating film formed on the top surface of said electric-charge transfer electrodes;a third insulating film formed on the side wall surface of said electric-charge transfer electrodes and said second insulating film; anda light shielding film formed on said second insulating film located above said channel region and on the side wall surface of said third insulating film, the end of said light shielding film extending above said light-receiving section, wherein the distance between the bottom of said light shielding film above said light-receiving section and said light-receiving section is 200 nm or less.
