Abstract: PURPOSE:To prevent junction leak in a photodetecting region and a charge transfer region, to reduce a dark current of an element substrantially, and to increases S/N ratio or sensitivity to realize uniformity by forming a CCD image sensing element inside an element formation region which is defined by a field oxide film formed by selective oxidation. CONSTITUTION:A CCD image sensing element is provided with a first offset region 14 and a second offset region 15 between an end of a field oxide film 5 to define an element formation region through selective oxidation (LOCOS method), and an end of an N<+>-type photo detecting region 13 of a photo diode(PD) and an n<+>-type electric charge transfer region 8 of CCD to avoid bringing a junction of a PD n<+>-type photo detecting region 13 and a CCD n<+>-type charge transfer region 8 into direct contact with an end of the field oxide film 5 where interface level occurs very much. Junction leak through the said interface level is thereby eliminated and dark current produced in the photo diode(PD) and CCD is greatly reduced, thus improving S/N ratio or sensitivity of the CCD image sensing element and reducing variations in sensitivity of picture elements.
