摘要： PROBLEM TO BE SOLVED: To improve the detection sensitivity and an S/N of a solid state imaging element for extremely high-speed imaging at million frames per second and more without impairing imaging speed. SOLUTION: A floating diffusion (FD) region 13 is formed at the edge of a light receiving surface of an embedded photodiode, and with a transfer gate electrode 12 therebetween. A first region 111 with a radially extending section centered on the FD region 13, and a second region 112 located outside the first region are created in the roughly fan-shaped light receiving surface. Impurities of the same conductivity types as signal electrical charges collected in the first region 111 are introduced, thus forming an electric field which directs the signal electrical charge from the radially extending section toward the center according to the three-dimensional electric field effect. As a result, an electrical charge transfer time is reduced. Additionally, since a circuit element for a subsequent stage can be disposed adjacent to the FD region 13, the parasitic capacitance of the FD region 13 can be reduced and a highly-sensitive element can be obtained.

摘要： PROBLEM TO BE SOLVED: To increase the number of recordable picture images without changing the area of a pixel signal recording section of a pixel surrounding recording type imaging device and the length of a transfer electrode of the imaging device in an imaging apparatus using the pixel surrounding recording type imaging device.
SOLUTION: A pixel signal recording section of the pixel surrounding recording type imaging device is constituted with an n-phase drive CCD when n is assumed to be a ≥5 integer. With the construction, (n-1)/2 electric potential wells are formed under successive n transfer electrodes when n is an odd number while (n-2)/2 electric potential wells are formed when n is an even number. Consequently, in the case of 4-phase drive, it is possible to increase a storable image signal to 2(n-1)/n times when n is an odd number while to 2(n-2)/n times when n is an even number. In other words, it is possible to increase the number of the storable image signal to 1.6 times if 5-phase drive is used, to about 1.7 times if 7-phase drive is used, and to about 1.8 times if 9-phase drive is used, as compared with ordinary 4-phase drive. It is possible to increase the number of storable images up to about twice without changing the area of the pixel signal recording section and the length of a transfer electrode.

摘要翻译：要解决的问题：为了增加可记录图像图像的数量而不改变记录型成像装置周围的像素的像素信号记录部分的面积和成像装置的转印电极的长度，使用围绕记录型成像装置的像素。解决方案：当n被假定为≥5整数时，围绕记录型成像装置的像素的像素信号记录部分由n相驱动CCD构成。通过构造，当n为奇数时，在连续的n个转移电极处形成（n-1）/ 2个电势阱，而当n为偶数时形成（n-2）/ 2个电势阱。因此，在4相驱动的情况下，当n是奇数时，可以将可存储的图像信号增加到2（n-1）/ n倍，而当n是2时，可以增加到2（n-2）/ n倍偶数换句话说，如果使用5相驱动，可以将可存储的图像信号的数量增加到1.6倍，如果使用7相驱动则可以将其增加到约1.7倍，如果9相驱动是与普通的4相驱动相比。可以在不改变像素信号记录部分的面积和转印电极的长度的情况下将可存储图像的数量增加大约两倍。版权所有（C）2004，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To prevent the mixing of signal charges in a rear-surface irradiation-type imaging device. SOLUTION: A rear-surface irradiation-type imaging device 1 is equipped with a conversion layer 21, a charge collection part 24, and suppression regions 23 and 29.
