چکیده
We describe a high optical performance 3.4 μm pixel pitch global shutter CMOS image sensor with multiple accumulation shutter technology and a large tapered light guide structure. The pixel achieves 1.8 etemporal noise and full well capacity of 16,200 ewith charge domain memory in 120 fps operation. The sensitivity and parasitic light sensitivity are 28,000 e-/lx·s and -89 dB, respectively. Moreover, the incident light angle dependence of sensitivity and parasitic light sensitivity has been improved by the large tapered light guide structure.

Development of Gentle Slope Light Guide Structure in a 3.4 μm Pixel Pitch Global Shutter CMOS Image Sensor with Multiple Accumulation Shutter Technology †
CMOS image sensors (CISs) with global shutter (GS) function are strongly required in order to avoid image degradation. However, CISs with GS function have generally been inferior to the rolling shutter (RS) CIS in performance, because they have more components. This problem is remarkable in small pixel pitch. The newly developed 3.4 µm pitch GS CIS solves this problem by using multiple accumula...

In this study, a 40 × 48 pixel global shutter complementary metal-oxide-semiconductor (CMOS) image sensor with an adjustable shutter time as low as 75 ps was implemented using a 0.5-μm mixed-signal CMOS process. The implementation consisted of a continuous contact ring around each p+/n-well photodiode in the pixel array in order to apply sufficient light shielding. The parasitic light sensitivi...

We report on 2and 4 megapixel backside illuminated image sensors with a 5.5 μm global shutter pixel manufactured in 0.18 μm CMOS. Global shutter pixels require an in-pixel storage node next to the photodiode. This storage node should not be light sensitive. This is specified by parasitic light sensitivity, which is the ratio of the amount of light detected by the storage node divided by the amo...

We have developed a 16Mpixel 3D stacked global-shutter CMOS image sensor with pixel level interconnections using 4 million micro bumps. The four photodiodes in the unit pixel circuit on the top substrate share one micro-bump interconnection at a 7.6μm pitch. Each signal of the photodiodes is transferred to the corresponding storage node on the bottom substrate via the interconnection to achieve...

This paper presents a 1 Megapixel CMOS image sensor which applies a dual charge transfer (dual-TX) scheme in the pixel to achieve a high dynamic range. The prototype sensor uses analog outputs and operates at maximum 20fps in rolling shutter. The sensor achieves 3.3etemporal noise and 99Kefull well capacity with 10m pixel pitch.
