Method for transferring charge, charge transfer device and solid state image sensing device using the same

摘要

In the method of transferring charges generated by signal charge generating sections in response to light, a signal charge existing under some transfer electrode of the plural charge transfer sections arranged in parallel to each other is transferred through one of a plurality of connecting sections formed under the transfer electrode corresponding to another charge transfer section among the plural connecting sections formed between the plural charge transfer sections, on the basis of a predetermined drive pulse; and when the charge is transferred to the other charge transfer section, a charge remaining at the primary charge transfer section is transferred from the primary charge transfer section to the other charge transfer section, through the other connecting section among the plural connecting sections, to combine the remaining charge with the signal charge previously transferred. A charge transfer device has a plurality of charge transfer sections arranged in parallel to each other and having a plurality of transfer electrodes, respectively for transferring signal charges generated by signal charge generating sections in response to light; a plurality of connecting sections formed between the plural transfer sections, for transferring a signal charge existing under some transfer electrode of the plural charge transfer sections to under another transfer electrode corresponding to the other charge transfer section on the basis of a drive pulse; and sections for combining a charge remaining at the primary charge transfer section with the signal charge previously transferred, when the charge is transferred to the other charge transfer section, by transferring the remaining charge from the primary charge transfer section to the other charge transfer section through the other connecting section among the plural connecting sections.
