ABSTRACT:
A semiconductor imaging device employing SIT (Static Induction Transistor) pixels having in the control gate region of each pixel a capacitor having optimum properties. Each pixel is constituted by an SIT having a pair of principal electrode regions of one conduction type facing one another through a highly resistive channel region. First and second gate regions of the other conduction type in contact with the channel region control the current flow between the two principal electrode regions. A transparent electrode is formed on at least part of the first gate region through a capacitor. Carriers generated by light excitation stored in the first gate region effectively control the current flow between the principal regions. A transparent electrically conductive layer is formed on the first gate region of each SIT through a nitride layer. The conductive layer serves as an electrode to connect the first gate region to the output of a gate control circuit.
