Abstract: A photo-sensing unit including a first electrode, a first insulation layer, a photo-sensing structure and a second electrode is provided. The first insulation layer covers the first electrode and has an opening exposing the first electrode. The photo-sensing structure is located on the first electrode and disposed in the opening of the first insulation layer. The photo-sensing structure includes a first photo-sensing layer and a second photo-sensing layer stacked with each other. A material of the first photo-sensing layer is SixGeyOz. A material of the second photo-sensing layer is SivOw. The second electrode covers the photo-sensing structure. A photo-sensing apparatus including the photo-sensing unit and a fabricating method of a photo-sensing unit are also provided.
