固体摄像装置和距离图像测量装置
摘要：
本发明涉及一种固体摄像装置以及距离图像测量装置。在所述固体摄像装置中，一对第1栅极(IGR、IGL)以光感应区域(SA)和一对第1存储区域(AR、AL)之间的电势(ΦTX1、ΦTX2)交替地倾斜的方式设置于半导体基板(100)上；一对第2栅极(IGR、IGL)以控制分别介于第1存储区域(AR、AL)和第2存储区域(FDR、FDL)之间的第1势垒(ΦBG)的高度的方式设置于半导体基板(100)上，并随着由光检测元件检测的背景光的输出变高而使相对于载流子的第1势垒(ΦBG)的高度增加。
摘要（英）：

A pair of first gate electrodes (IGR, IGL) are arranged on a semiconductor substrate (100) so that potentials phiTX1, phiTX2 between a photo sensing region (SA) and a pair of first accumulation areas (AR, AL) are alternately inclined. A pair of second gate electrodes (IGR, IGL) are arranged on the semiconductor substrate (100) so as to control the height of a first potential barrier phiBG arranged between the first accumulation areas (AR, AL) and the second accumulation areas (FDR, FDL), respectively. As the output of the background light detected by a photo detector increases, the height of the the barrier phiBG of the first potential for the carrier is increased.
