  • Patent number: 12627907
    Abstract: An imaging device comprises a pixel including a photoelectric conversion device for generating pixel signals, a floating diffusion region, a first dual conversion gain (DCG) transistor for providing additional capacitance to the floating diffusion region, and a first DCG capacitor connected to the floating diffusion region through the first DCG transistor; and an analog-digital converter (ADC) for converting the pixel signals into image data, wherein the pixel includes a first metal layer including a first DCG gate electrode of the first DCG transistor and a first electrode of the first DCG capacitor, a second metal layer including a dual conversion line that supplies a first DCG gate signal to the first DCG gate electrode, and a second electrode overlapping the first electrode, a first insulating layer between the first DCG gate electrode and the dual conversion line, and a second insulating layer between the first electrode and the second electrode.

  • Publication number: 20260129312
    Abstract: Image sensing devices capable of implementing multiple gains are disclosed. In an embodiment, an image sensing device includes a first pixel including first and second dual conversion gain (DCG) transistors that adjust capacitance of a first floating diffusion region shared by a plurality of pixels included in a first pixel group; and a second pixel including third and fourth DCG transistors that adjust capacitance of a second floating diffusion region shared by a plurality of pixels included in a second pixel group arranged at one side of the first pixel group. A gate of the first DCG transistor and a gate of the second DCG transistor are arranged closer to the second pixel from a center of the first pixel, and a gate of the third DCG transistor and a gate of the fourth DCG transistor are arranged closer to the first pixel from a center of the second pixel.
