A new resistive sea for diode array vidicons

A new kind of resistive sea for silicon diode arrays has been developed. It is an electronically conducting glass that can be r-f sputtered reproducibly to give the desired combination of resistance and thickness. Since the resistivity can be varied over a wide range (10³to 10¹⁴ohm-cm) the thickness can be chosen independently of the sheet resistivity. Furthermore, the material can be baked at a temperature of 300°C without degrading tube performance. Data on the processing and performance of the material will be presented.
