A solid state imaging device comprises a transparent electrode, a photoconductive layer, and a plurality of scanning circuits for consecutively selecting signals in the photoconductive layer. The photoconductive layer is formed of amorphous semiconductor comprising amorphous silicon as the major component and further containing an element serving to lower the capture level within the energy gap and a trace amount of chalcogen element as a chemical modifier.

Solid state image device

A solid state image pickup device comprising a semiconductor substrate provided with light detecting sections and a scanning circuit for sequentially selecting the signals detected by the light detecting sections, wherein each light detecting section contains a silicon layer in which microcrystalline silicon and amorphous silicon are uniformly distributed and the crystal structure varies substantially continuously throughout. The light detecting section may further contain a hydrogenated amorphous silicon layer containing 6 to 37 atomic % of nitrogen, which is positioned on the silicon layer defined above. The light detecting section is connected with electrodes, one of which is transparent.

Solid state image pickup device utilizing microcrystalline and amorphous

A solid state imaging device using a non-crystalline semiconductor material as a photoconductive member. The photoconductive member is arranged in repetitive p-i-n layers such that an opto electromotive force is developed sufficient to drive charges to an integrated scanning circuit even in the absence of an external bias voltage.

Solid state imaging device

In the course of producing a thin film of amorphous silicon by high frequency sputtering elemental silicon under an atmosphere containing at least hydrogen gas, the temperature of the base plate onto which the amorphous silicon is deposited is maintained at a temperature of about 50.degree. C. to 150.degree. C. The thus obtained silicon film possesses not only photoconductivity sufficient for use as a photoconductor but also a large difference between photoconductivity and dard conductivity. In addition, a photoconductor of an amorphous silicon thin film can be produced at low cost without environmental pollution problems.

High frequency sputtering produces thin film amorphous silicon

An improved type of thin film photovoltaic cell can be produced by forming a thin layer of n-type CdTe up to 2 micron thick on a conductive support, heat-treating the CdTe layer at 80.degree. to 210.degree. C. for 20 to 180 minutes, and providing on the free surface of the heat-treated CdTe layer a transparent electrode.

Thin film photovoltaic cell and a method of manufacturing the same

A process for forming color images which comprises image-wise exposing a silver halide photographic material, subjecting the exposed photographic material to color development and then fixing the developed material with a fixing bath having a pH of at least 6, the process being free from a silver bleaching (elimination) step. The process is especially suitable for application to radiographic materials.
