    摘要: A solid-state imaging device and an optical sensor, which can enhance a wide dynamic range while keeping a high sensitivity with a high S/N ratio, and a method of operating a solid-state imaging device for enhancing a wide dynamic range while keeping a high sensitivity with a high S/N ratio are disclosed. An array of integrated pixels has a structure wherein each pixel comprises a photodiode PD for receiving light and generating and accumulating photoelectric charges and a storage capacitor element CS coupled to the photodiode PD through a transfer transistor Tr1 for accumulating the photoelectric charges overflowing from the photodiode PD. The storage capacitor element CS is structured to accumulate the photoelectric charges overflowing from the photodiode PD in a storage-capacitor-element accumulation period TCS that is set to be a period at a predetermined ratio with respect to an accumulation period of the photodiode PD.

    摘要: An independent pixel output line (14) is provided for each of two-dimensionally arranged pixels (10) within a pixel area (2a). A plurality of memory sections are connected to each pixel output line (14). In a continuous reading mode, photocharge storage is simultaneously performed at all the pixels, and signals are collectively transferred from the pixels (10) through the pixel output lines (14) to the memory sections, after which the signals held in the memory sections are sequentially read and outputted. In a burst reading mode, the operations of simultaneously storing photocharges at all the pixels and collectively transferring signals from each pixel (10) through the pixel output line (14) to the memory sections are sequentially performed for each of the memory sections to hold signals corresponding to a plurality of frames. When a imaging halt command is given, the holding of new signals is halted, and a plurality of frames of image signals held in the memory sections at that point in time are sequentially read and outputted. Thus, both an ultrahigh-speed imaging operation with a limitation on the number of frames and an imaging mode that is rather slow but has no limitation on the number of frames can be performed.

    摘要: A floating diffusion (331) is created substantially at center of the light-receiving surface of an embedded photodiode (31), with a gate electrode of a transfer transistor (32) surrounding the floating diffusion. The concentration (or depth) of impurities in a p+-type semiconductor region, n-type semiconductor region or p-well region is changed in an inclined form so that a potential gradient being inclined downwards from the circumference to the center is created when an appropriate bias voltage is applied to the pn junction. The photocharges produced by incident light are rapidly moved along the potential gradient toward the center. Even in the case where the photocharge storage time is short, the photocharges can be efficiently collected since the maximum moving distance from the circumference of the photodiode (31) to the floating diffusion (331). Thus, the photocharges produced by the photodiode (31) are efficiently utilized, whereby the detection sensitivity is improved.

    摘要: A low noise amplifier is assumed to comprise an MIS transistor and to amplify an input signal keeping noise at a low level, and the MIS transistor comprises a semiconductor substrate for comprising a first crystal plane as a principal plane, a semiconductor structure, formed as a part of the semiconductor substrate, for comprising a pair of sidewall planes defined by the second crystal plane different from the first crystal plane and a top plane defined by the third crystal plane different from the second crystal plane, a gate insulator of uniform thickness covering the principal plane, the sidewall planes and the top plane, a gate electrode for continuously covering the principal plane, the sidewall planes and the top plane on top of the gate insulator, and a single conductivity type diffusion area formed in the region to either side of the gate electrode in the semiconductor substrate and the semiconductor structure and continuously extending along the principal plane, the sidewall planes and the top plane. Such a configuration allows significant reduction of the 1/f noise and the signal distortion applied to an output signal by the low noise amplifier and therefore a circuit for compensating for the reduction of the amplitude is no longer of necessity, allowing reduction in size.
