As shown in FIG. 1, the in-pixel GND contact 2 and the first conductivity type well region 3 are arranged at the center of one side of, for example, the rectangular photodiode portion 1. The advantages of this arrangement are as follows.
- the intra-pixel GND contact 2 By disposing the intra-pixel GND contact 2 in the photodiode portion 1, the intra-pixel GND contact 2 is located inside the light-shielding aluminum opening 7 and exposed to the light incident portion.
- the GND contact 2 in the pixel is asymmetric in the photodiode section 1.
- the output of the lower right pixel in the imaging region is lower than that of the pixel at the center of the imaging region.
- the focal position in the pixel is larger toward the corner of the photodiode portion 1 in the pixel on the outermost diagonal of the imaging region compared to the pixel in the center of the imaging region.
- the in-pixel GND contact is arranged at the lower right of the photodiode part 1, the proportion of incident light that is focused on the in-pixel GND contact is relatively increased in the lower right pixel in the imaging region. .
- the photoelectric conversion rate is lower in the lower right pixel in the imaging region than in the pixel in the center of the imaging region.
- the output of the upper right corner of the screen decreases. The condition becomes worse.
- the cause of the output asymmetry in the imaging region is closely related to the location of the in-pixel GND contact 2 in the photodiode portion 1 as described above.
- the GND contact in the pixel is arranged at the lower right of the photodiode part 1 is explained.
- the force is applied to the corner of the rectangular photodiode part 1 such as the upper right or upper left of the photodiode part 1. If the GND contact in the pixel is placed, it is affected by the characteristics of the light incident on the imaging area.
- the center of the imaging region optically has the longest distance.
- the ratio of the light collected on the GND contact 2 in the pixel can be reduced.
- the occurrence of asymmetry in the diagonal direction of the screen can be suppressed.

- FIG. 3A is a plan view schematically showing an imaging region (only four pixels are shown) 9.
- FIGS. 3B and 3C are plan views showing the layout in the pixel.
- a feature of this embodiment is that two or more types of pixels having different positions of the GND contact in the pixel are arranged in the imaging region 9. That is, in the pixel A, the in-pixel GND contact 2a and the first conductivity type well region 3a are arranged on the right side of the upper side of the photodiode 1. In the pixel B, the in-pixel GND contact 2b and the first conductivity type wall region 3b are arranged on the left side of the upper side of the photodiode 1. As shown in FIG. 3A, pixels A are arranged in the upper left and lower right in the imaging area 9, and pixels B are arranged in the lower left and upper right.
- the light incident on each pixel in the imaging region 9 is, for example, a force that is collected on the photodiode unit 1 by a lens provided on each pixel. Since the irradiating light is incident obliquely, the condensing position on the photodiode portion 1 is deviated depending on the pixel position in the imaging region 9. For example, in the pixel A region, the light condensing position on the photodiode portion 1 is substantially deviated in the direction of the upper left force and lower right, and in the pixel B region The light condensing position on the diode part 1 is generally biased in the direction of the lower left force and upper right. For this reason, it is preferable to provide the intra-pixel GND contacts 2a and 2b while avoiding the positions along the direction in which the light condensing position is deviated, thereby preventing variation in sensitivity between pixels.
- the positions of the GND contacts in the pixel may be two types, and the arrangement may be different for all the pixels.
- the lever position can be gradually changed from the center of the imaging region 9.
- the dividing method is not limited as long as the same effect can be obtained.
- Embodiment 4 An amplification type solid-state imaging device according to Embodiment 4 will be described.
- the pixel layout of this embodiment differs from the conventional example of FIG. 5 in that the pixel portion GND contact 2 and the first conductivity type well region 3 are not connected to the adjacent photodiode portion 1 as shown in FIG. It is not separated by the active region. That is, the pixel portion GND contact 2 and the photodiode portion 1 are formed in the same active region and are not separated by the inactive region.
- the in-pixel GND contact 2 is arranged in the photodiode portion 1.
- the potential of the floating diffusion capacitance 45 is set to the maximum power supply voltage, for example, 5V.
- the potential difference is 5V.
- the contact injection portion 53 (see FIG. 6) used for connection with the first conductivity type well region 43 and the floating diffusion capacitor 45 are in contact with each other at a high concentration, so that the breakdown due to the electric field is likely to occur. Therefore, it is essential to provide the inactive region 48.
- the maximum potential of the photodiode portion 1 is about 2 V at the maximum, and the potential difference with the GND contact 2 in the pixel is small. Concentration is low with respect to the impurity concentration by forming the floating diffusion capacitor part 5. Therefore, even if there is no separation by the non-active region 8, it will not be destroyed. With this structure, there is an effect that it is possible to suppress the generation of dark output and the generation of white flaws without the occurrence of defects due to the formation of inactive regions.
- the potential of the well region 3 can be stabilized as long as the in-pixel GND contact 2 is not limited to the ground but can be fixed to a constant reference potential. Togashi.
- the GND contact 2 in the pixel does not necessarily need to completely fit in the rectangle of the photodiode portion 1. A part of the GND contact 2 may protrude from the rectangle.
- the amplification type solid-state imaging device of the present invention improves the afterimage characteristics, has a rational arrangement of GND contacts in the pixel that does not adversely affect the optical characteristics, and has a large image formation size. This is useful for high-end digital still cameras, dental X-ray input solid-state imaging devices, and face contour image input devices.
