Abstract
A semiconductor memory device provided with one transferring electrode, one gate electrode and one diode of a charge coupled device is produced by a process with a reduced number of steps of diffusion and patterning. Both electrodes consists of doped polycrystalline silicon and both are electrically connected to a resistive layer which consists of non-doped polycrystalline silicon. A potential barrier between the region of both electrodes is removed due to the resistive layer. Resistive layer is formed by utilization of a two-stage deposition of the polycrystalline silicon layer with appropriate mashing steps.
