INFRARED IMAGE SENSOR

摘要

An image sensor includes a substrate, dual-waveband photosensitive devices, at least one infrared photosensitive device, a transparent dielectric layer, at least one infrared band-pass filter, a color filter layer and a micro-lens layer. The dual-waveband photosensitive devices are disposed in the substrate, and each dual-waveband photosensitive device is configured to sense an infrared light and one visible light. The infrared photosensitive device is disposed in the substrate, in which the dual-waveband photosensitive devices and the infrared photosensitive device are arranged in an array. The transparent dielectric layer is disposed over the dual-waveband photosensitive devices and the infrared photosensitive device. The infrared band-pass filter is disposed in the transparent dielectric layer and corresponds to the infrared photosensitive device. The color filter layer is disposed to cover the transparent dielectric layer and the infrared band-pass filter. The micro-lens layer is disposed on the color filter layer.
