    摘要: Disclosed is a non-volatile semiconductor memory device that uses a inversion layer provided on a semiconductor substrate as a data line. The memory device can reduce variation of characteristics among memory cells and can reduce bit cost. A plurality of assist gates are formed in the upper part of a p-type well through a gate oxide film. In the upper part of an interlayer insulator that covers those assist gates are formed word lines that are used as control electrodes. The width of those word lines is, for example, 0.1 μm, and each word line is separated from its adjacent word lines by a side wall spacer that is a silicon oxide film having a thickness of about 20 nm.

    摘要: In a semiconductor flash memory required to have high reliability, injection and extraction of electrons must be performed through an oxide film obtained by directly oxidizing a silicon substrate. Accordingly, the voltage to be used is a large voltage ranging from positive to negative one. In contrast, by storing charges in a plurality of dispersed regions, high reliability is achieved. Based on the high reliability, transfer of electrons is permitted through not only the oxide film obtained by directly thermally oxidizing a high reliability silicon substrate but also another oxide film deposited by CVD, or the like. In consequence, a device is controlled by electric potentials of the same polarity upon writing of data and upon erasing of data.

    摘要: An object of the present invention is to provide a semiconductor memory device suitable for larger-capacity storage because of its ability to store 3 or more bits in one element and capable of a high-speed and high-efficiency write operation due to a reduced leakage current during the write operation and provide a fabrication method therefor. According to the present invention, each of elements has a source region, a drain region, a control gate, two charge storage regions, and one or more assist gates. During a write operation, source side injection writing is performed with respect to a write target element by using the assist gates, while adjacent elements are isolated by field isolation using the assist gates.
