摘要: In each photosensitive cell, a photodiode 101, a transfer gate 102, a floating diffusion layer section 103, an amplifier transistor 104, and a reset transistor 105 are formed in one active region surrounded by a device isolation region. The floating diffusion layer section 103 included in one photosensitive cell is connected not to the amplifier transistor 104 included in that cell but to the gate of the amplifier transistor 104 included in another photosensitive cell adjacent to the one photosensitive cell in the column direction. A polysilicon wire 111 connects the transfer gates 102 arranged in the same row, and a polysilicon wire 112 connects the reset transistors 105 arranged in the same row. For connection in the row direction, only polysilicon wires are used.

摘要: Photosensitive cells each includes a photodiode (1), a transfer gate (2), a floating diffusion layer portion (3), an amplifying transistor (4), and a reset transistor (5). Drains of the amplifying transistors (4) of the photosensitive cells are connected to a power supply line (10), and a pulsed power supply voltage (VddC) is applied to the power supply line (10). Here, a low-level potential (VddC_L) of the power supply voltage has a predetermined potential higher than zero potential. Specifically, by making the low-level potential (VddC_L) higher than channel potentials obtained when a low level is applied to the reset transistors (5), or channel potentials obtained when a low level is applied to the transfer gates (2), or channel potentials of the photodiodes (1), a reproduced image with low noise is read.

摘要: During an exposure time period (long accumulation time period) of a low shutter speed shooting mode, a second reference voltage Vss2, which is different from a first reference voltage Vss1 (a ground voltage) corresponding to a reference voltage of a peripheral circuit, is applied to a well (5) where a photoelectric converter section (2) and a drain region (4) are formed, whereby generation of dark electrons at a portion of a surface of the well (5) below a gate electrode (6) is suppressed. A polarity of the second reference voltage Vss2 is positive in the case where a conductivity type of the well (5) is a P-type, and is negative in the case of an N-type.

Each photosensitive cell includes a photodiode formed to be exposed on a surface of a semiconductor substrate for the purpose of accumulating signal charge obtained by subjecting incident light to photoelectric conversion, a transfer transistor for transferring signal charge accumulated by the photodiode, a floating diffusion layer for temporarily accumulating signal charge transferred by the transfer transistor, and an amplifier transistor for amplifying signal charge temporarily accumulated in the floating diffusion layer. A source/drain diffusion layer provided in the amplifier transistor is covered with a salicide layer, and the floating diffusion layer is formed to be exposed on a surface of the semiconductor substrate.
