Abstract
The invention is to simplify a producing process for a solid-state image pickup device having pixels including MOS transistors, thereby improving productivity of the image pickup device. In a producing method for a solid-state image pickup device including pixelseach including a photoelectric conversion regionfor generating photoelectrically a carrier and accumulating the carrier photoelectrically generated, a carrier accumulating portionfor accumulating a carrier overflowing from the photoelectric conversion regionin a period of carrier generation and accumulation thereof, and a MOS transistor Tx-MOS for transferring the carrier overflowing from the photoelectric conversion region, wherein a gate electrode of the MOS transistor Tx-MOS is formed in the same step as the step of forming a polysilicon filmconstituting the first electroconductive film of the carrier accumulating portion
