Abstract
A solid state photo-electric converting device consists of a direct conjunction of a photo-electric converting layers formed of satisfactorily selected materials and a solid state amplifier formed, for instance, of an FET, a conductive electrode being inserted therebetween for collecting signal charges induced in those converting layers efficiently, thereby an excellent spectral sensitivity performance and an extremely high conversion efficiency being realizabe. Accordingly, a solid state imaging apparatus employing a matrix of the above converting devices can be provided with an excellent spectral and noiseless performance.
Claims20
A photo-electric converting device, wherein an amount of an incoming light is converted into an electric signal, comprising
- a solid state photo-electric converting means consisting of at least
- a photo-transparent electrode layer,
- at least one photo-electric converting layer and
- a conductive electrode layer covering substantially the same area as said photo-electric converting layer for collecting signal charges converted from the incoming light in said at least one photo-electric converting layer, and
