1/2.3インチ1.55μm pixel 12M画素インターライントランスファー型CCDの開発(携帯電話用カメラ,デジタルスチルカメラ,ビデオカメラ(ハイビジョン)とそのためのイメージセンサ,モジュール)  [in Japanese] High-saturation output 1.55-μm-square pixel IT-CCD with metal wiring line structure  [in Japanese]

Abstract

C-DSC(Compact Digital Still Camera)向けの1.55μm pixel 1/2.31 inch 12M画素のインターライントランスファー型のCCDの開発を行った。このCCDは、高い感度と飽和出力を兼ね備えていることを特徴とする。本報告では、このうち高い飽和出力を得るために採用している技術について報告をする。

This paper describes the device performance of a 1.55-μm-square pixel interline transfer CCD (IT-CCD) having 12M pixels in a 1/2.3-inch optical format. The device has a novel metal wiring structure designed to increase the saturation signal that is determined by the effective supply voltage at the read-out gate, and employs a lateral overflow drain architecture to assist the low anti-blooming capability of the vertical overflow drain in the photodiode. As a result, we achieve a 14% higher saturation signal, and an anti-blooming performance that is 30-times superior to a 1.75-μm-square pixel CCD, despite the 27% smaller pixel area. These novel structures do not influence other performances of the device..
