Abstract
An image sensor comprises switching elements 30 on a substrate 1. An insulating separation layer 9 is disposed over the switching elements so that a photodiode arrangement 20a disposed over the insulating separation layer 9, can overlap the switching elements 30 and occupy a maximum area of the image sensor. A barrier layer 10 is interposed between the insulating separation layer 9 and the photodiode arrangement 20a, which prevents degradation of the photodiode characteristics over time.
