Imaging device and electronic apparatus
There is provided an imaging device that includes photovoltaic type pixels that have photoelectric conversion regions generating photovoltaic power for each pixel depending on irradiation light; and an element isolation region that is provided between the photoelectric conversion regions of adjacent pixels and in a state of substantially surrounding the photoelectric conversion region.
Solid-state imaging device with channel stop region with multiple impurity regions in depth direction and method for manufacturing the same
Channel stop sections formed by multiple times of impurity ion implanting processes. Four-layer impurity regions are formed across the depth of a semiconductor substrate (across the depth of the bulk), so that a P-type impurity region is formed deep in the semiconductor substrate; thus, incorrect movement of electric charges is prevented. Other four-layer impurity regions of another channel stop section are decreased in width step by step across the depth of the substrate, so that the reduction of a charge storage region of a light receiving section due to the dispersion of P-type impurity in the channel stop section is prevented in the depth of the substrate.

Image sensor with buried-channel drain (BCD) transistors
A charge-coupled device (CCD) image sensor is provided. The CCD image sensor may include an array of photosensors that transfer charge to multiple vertical CCD shift registers, which then in turn transfer the charge to a horizontal CCD shift register. The horizontal CCD shift register then feeds an output buffer circuit. The output buffer circuit can include a load transistor implemented using a buried-channel drain (BCD) structure. The load transistor may include a gate conductor, a source diffusion region, a drain diffusion region, and a buried-channel drain region that at least partially extends under the gate conductor. The BCD region may be formed before or after the formation of the gate conductor. If desired, the BCD region can also be formed at the source edge. An image sensor configured in this way can exhibit higher source-drain breakdown voltages, enhanced amplifier gain, and reduced amplifier glow.

The first substrate and second substrate are stacked together, and the relay part 240 electrically couples the charge transfer parts of the first substrate to the charge storage parts of the second substrate by means of a connecting parts passing through the substrates outside the photosensitive region of the photosensitive part.

CMOS image sensor and a method of forming the same
A complementary metal-oxide-semiconductor (CMOS) image sensor includes an implant region of a second type formed in a crystalline layer of a first type. A channel of a transfer gate entirely covers the implant region, which partially joins a photodiode, a doped well and a floating diffusion node.
Pumped pinned photodiode pixel array
The present invention relates to a pumped pixel that includes a first photo-diode accumulating charge in response to impinging photons, a second photo-diode, and a floating diffusion positioned on a substrate. The pixel also includes a charge barrier positioned on the substrate between the first photo-diode and the second photo-diode, where the charge harrier temporarily blocks charge transfer between the first photo-diode and the second photo-diode. A pump gate may also be formed on the substrate adjacent to the charge barrier. The pump gate pumps the accumulated charge from the first photo-diode to the second photo-diode through the charge barrier. Also included is a transfer gate positioned on the substrate between the second photo-diode and the floating diffusion. The transfer gate serves to transfer the pumped charge from, the second photo-diode to the floating diffusion.
