Abstract
An infrared sensor includes a substrate, an active pixel array, a reference pixel array, a light absorbing layer, a sidewall spacer, and a shading layer. The active pixel array is over the substrate. The reference pixel is over the substrate, adjacent to the active pixel array, and having a reference pixel. The reference pixel includes a platform, a resistor, and an infrared sensing material layer. The resistor is on the platform. The infrared sensing material layer is over the resistor. The light absorbing layer is over the reference pixel. The sidewall spacer is over the reference pixel and extends along a sidewall of the light absorbing layer. The shading layer is conformally formed over the light absorbing layer and the sidewall spacer.
