    摘要: A cell structure of a non-volatile memory device, which uses a nitride layer as a floating gate spacer, includes a gate stack and a floating gate transistor formed over a semiconductor substrate. The gate stack includes a first portion of a floating gate, a control gate formed over the first portion of the floating gate, and a non-nitride spacer adjacent to sidewalls of the first portion of floating gate. The floating gate transistor includes a second portion of the floating gate, which substantially overlaps a source and/or drain formed in the substrate. The application of ultraviolet rays to the non-nitride spacer of a programmed cell can causes the second portion of the floating gate to discharge, thereby easily erasing the programmed cell.

    摘要: A dual port semiconductor memory device, including PMOS scan transistors, is provided. The dual port semiconductor memory device includes two PMOS transistors, two NMOS pull-down transistors, two NMOS pass transistors, and a PMOS scan transistor. The scan transistor being PMOS, noise margins can be improved. In addition, these seven transistors are arranged in two n-wells and 2 p-wells, while n-wells and p-wells are arranged in series and in alternating fashion. Therefore, the length of a memory cell along the minor axis of the memory cell is relatively short. This memory cell layout helps shorten the length of a bit line by arranging a pair of bitlines in parallel with well boundaries, i.e., in the direction of the short axis of the memory cell, and makes it possible to prevent crosstalk between a bitline and a complementary bitline by arranging conductive lines between the bitline and the complementary bitline.

    摘要: A high-voltage semiconductor device and a method of manufacturing the high-voltage semiconductor device are provided. For example, with the above device and method drift regions having first depths are formed in a semiconductor substrate by doping first impurities. The drift regions are spaced apart from each other to define a channel region between the drift regions. Source/drain regions having second depths are formed at first portions of the drift regions by doping second impurities. Impurity accumulation regions having third depths are formed at second portions of the drift region adjacent to the source/drain regions by doping third impurities. A gate insulation layer pattern is formed on the semiconductor substrate to partially expose the source/drain regions. A gate conductive layer pattern is formed on a portion of the gate insulation layer pattern where the channel region is positioned. A buffer layer capable of preventing a rapid increase of a current is formed on the gate structure and the gate insulation layer pattern.
