An imaging element has a laminated structure including a first electrode, a light-receiving layer formed on the first electrode, and a second electrode formed on the light-receiving layer. The second electrode is made of a transparent amorphous oxide having a conductive property.

The instant disclosure provides an optical component packaging structure which includes a far-infrared sensor chip, a first metal layer, a packaging housing and a covering member. The far-infrared sensor chip includes a semiconductor substrate and a semiconductor stack structure. The semiconductor substrate has a first surface, a second surface which is opposite to the first surface, and a cavity. The semiconductor stack structure is disposed on the first surface of the semiconductor substrate, and a part of the semiconductor stack structure is located above the cavity. The first metal layer is disposed on the second surface of the semiconductor substrate, the packaging housing is used to encapsulate the far-infrared sensor chip and expose at least a part of the far-infrared sensor chip, and the covering member is disposed above the semiconductor stack structure.

The use of silicon or vanadium oxide nanocomposite consisting of graphene deposited on top of an existing amorphous silicon or vanadium oxide microbolometer can result in a higher sensitivity IR detector. An IR bolometer type detector consisting of a thermally isolated nano-sized (<one micron feature size) electro-mechanical structure comprised of Si3N4, SiO2 thins films, suspended over a cavity with a copper thin film reflecting surface is described. On top of the suspended thin film is a nanostructure composite comprised of graphene monolayers, covered with various surface densities of VoXy or amorphous nanoparticles, followed by another graphene layer. The two conducting legs are connected to a readout integrated circuit (ROIC) fabricated on a CMOS wafer underneath. The nanostructure is fabricated after the completion of the ROIC process and is integrate able with the CMOS process.
