WebThe drawback to a back-thinned CCD is etaloning. As light passes through the thinned region (10 to 20 μm thick), a small percentage of the light hits structures, or layers, near the front side and reflects back into the active region, generating electrons (signal). This is particularly noticeable in the red and near-IR regions. WebFigure 1: QE curves of a typical back-illuminated silicon CCD and an InGaAs sensor.
