Abstract
A semiconductor device may include a first sensor configured to sense light having a wavelength within a first wavelength range from incident light and generates a first electrical signal based on the sensed light and a second sensor configured to sense light having a wavelength within a second, different wavelength range from the incident light and generates a second electrical signal based on the sensed light. The first and second sensors may be electrically connected to each other via an intermediate connector, and the first sensor and the second sensor may share a pixel circuit that is electrically connected thereto via the intermediate connector. The first and second wavelength ranges may include infra-red and visible wavelength ranges, respectively. The first and second wavelength ranges may include different visible wavelength ranges.
