    摘要: In preparing an image pickup device by using hydrogen-containing amorphous silicon for a photoconductive layer, a hydrogen-containing amorphous silicon layer is first formed and is then heat-treated at 100.degree. to 300.degree. C. The image pickup characteristics of the amorphous silicon layer are highly improved by this heat treatment. For example, the lag and dark current are reduced and the signal current-target voltage characteristic is improved. Especially excellent improving effects can be obtained when amorphous silicon characterized in that (1) the hydrogen content is 5 to 30 atomic %, (2) the optical forbidden band gap is 1.30 to 1.95 eV and (3) in the infrared absorption spectrum, the component of a wave number of 2000 cm.sup.-1 is observed larger than the component of a wave number of 2100 cm.sup.-1 is subjected to the above-mentioned heat treatment. The adhesion to the substrate is enhanced, and good image pickup characteristics can be obtained.

    摘要: A photoelectric device having at least a predetermined impurity region which is disposed in a semiconductor substrate, and a photoelectric conversion portion which is constructed by stacking an electrode layer lying in contact with at least a part of the impurity region, a photoconductive material layer overlying the electrode layer, and a transparent electrode overlying the photoconductive material layer, characterized in that the photoconductive material layer is made of an amorphous chalcogenide material which principally contains Se, is disclosed. It is very favorable that the photoelectric conversion material layer made of the amorphous material principally containing Se is partially doped with Te so as to enhance its sensitivity. The amorphous chalcogenide material is very useful in the following point. In the course of forming, or after having formed, at least one photoconductive layer on a semiconductor body whose surface is uneven, a heat treatment is performed at a temperature of at least the softening point of the photoconductor so as to flatten the layer, whereby discontinuous parts of the photoconductor ascribable to the uneven surface of the semiconductor body can be avoided.
