摘要: 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.

摘要: A distance between two electrodes of a CCD device is reduced to an extremely small value, thereby increasing the memory density, of the CCD device. In the process of the present invention, upon formation of a first electrode, an insulating layer is formed on the entire top surface of the semiconductor wafer. The material of another electrode is then placed on the entire top surface of the wafer. These layers are then selectively removed to form a CCD structure.

摘要: A nonvolatile semiconductor memory device of a floating-gate type comprises a floating-gate and two control gates. The floating-gate is divided into two conductive regions having a conductivity type opposite to each other. A first control gate is placed above a first region and a second control gate is placed above a second region. In this device, the erase operation is performed by causing avalanche breakdown within the floating-gate.

摘要: Disclosed herein is a semiconductor memory device comprising a semiconductor substrate having a first conductivity type, first and second regions of a second conductivity type opposite to said first type formed in the surface of the semiconductor substrate and separated with a certain space therebetween, a third region of the first conductivity type formed in the second region, and a gate electrode formed on an insulating film on the semiconductor substrate between the first and the third regions. By applying a gate voltage to the gate electrode, charge carriers are transferred between the first and second regions in accordance with the data to be stored. The stored data is read out by applying a prescribed gate voltage to the gate electrode and by detecting the value of the current between the third region and the semiconductor substrate.
