1. Field of the Invention
The present invention pertains to a solid state light-sensitive device.
2. Description of the Prior Art
The making of solid state light-sensitive devices is well known in the prior art. These devices are of the type comprising:
A network of horizontal conductors or rows and a network of vertical conductors or columns intersecting at a matrix of crosspoints;
A light-sensitive element which connects each intersecting row and column;
An addressing circuit, the outputs of which are linked to the rows;
A reading and multiplexing circuit, the inputs of which are linked to the columns.
In all these light-sensitive devices, it is sought to simplify the patterns and technologies used to the maximum extent in order to make the light-sensitive elements in such a way as to increase manufacturing output. It is also sought to decrease the capacitances of the various connections, thus making it possible to simplify the electronic circuits connected to the device. Finally, it is sought to reduce the dark currents (which are harmful) of the light-sensitive devices.
These considerations are all the more important when large-sized light-sensitive devices have to be made, as is the case with X-ray optical image formation where the radiation cannot be focused.
