Claim Text:
1. An image sensor device, comprising: a substrate having a pixel area and a peripheral area; a first image sensing structure stacked on the substrate, the first image sensing structure having a first portion in the pixel area for sensing incident light in a red color wavelength band and a second portion in the peripheral area; a first insulating layer on the first portion of the first image sensing structure; a first conductive through-silicon via (TSV) in the second portion of the first image sensing structure; a first conductive bump structure on the first conductive TSV; a second image sensing structure stacked on the first insulating layer and the first conductive bump structure, the second image sensing structure having a third portion in the pixel area for sensing incident light in a green color wavelength band and a fourth portion in the peripheral area; a second insulating layer on the third portion of the second image sensing structure; a second conductive TSV in the fourth portion of the second image sensing structure; a second conductive bump structure on the second conductive TSV; and a third image sensing structure stacked on the second insulating layer and the second conductive bump structure, the third image sensing structure having a fifth portion in the pixel area for sensing incident light in a blue color wavelength band and a sixth portion in the peripheral area.
