摘要:
A pre-amplifier (column region unit) of a solid-state imaging device including a pixel-signal controller. The pixel-signal controller, for each vertical signal line, detects the level of each pixel signal independently by a pixel-signal detector on the output side of a pixel-signal amplifier, and sets a gain independently to the pixel-signal amplifier according to the level of the signal. At a subsequent stage of the solid-state imaging device, an analog-to-digital (A/D) converter and a signal extending unit are provided. The A/D converter digitizes a pixel signal, and the digitized pixel signal is corrected by a gain set to the pixel-signal amplifier with reference to a classification signal from the pixel-signal detector, so that the dynamic range of signals of one screen is extended.

摘要:
Solid-state image pickup device and processing method, with A/D conversion on pixel signals read from a pixel array part that effectively achieves reductions in power consumption, size and price while retaining a high-quality image output. The device includes a pixel array part, a CDS (correlated double sampling) circuit, and an A/D converter. A pixel signal read via a signal line is subjected to noise elimination processing in the CDS circuit, and is then inputted into the A/D converter. The A/D converter includes a ΔΣ modulator and a digital filter to perform highly accurate A/D conversion. The A/D converter can also be provided at the front stage of the CDS circuit.

Forming a back-illuminated type CMOS image sensor, includes process for formation of a registration mark on the wiring side of a silicon substrate during formation of an active region or a gate electrode. A silicide film using an active region may also be used for the registration mark. Thereafter, the registration mark is read from the back side by use of red light or near infrared rays, and registration of the stepper is accomplished. It is also possible to form a registration mark in a silicon oxide film on the back side (illuminated side) in registry with the registration mark on the wiring side, and to achieve the desired registration by use of the registration mark thus formed.

摘要:
P type semiconductor well regions 8 and 9 for device separation are provided in an upper and lower two layer structure in conformity with the position of a high sensitivity type photodiode PD, and the first P type semiconductor well region 8 at the upper layer is provided in the state of being closer to the pixel side than an end portion of a LOCOS layer 1A, for limiting a dark current generated at the end portion of the LOCOS layer 1A. In addition, the second P type semiconductor well region 9 at the lower layer is formed in a narrow region receding from the photodiode PD, so that the depletion layer of the photodiode PD is prevented from being obstructed, and the depletion is secured in a sufficiently broad region, whereby enhancement of the sensitivity of the photodiode PD can be achieved.
