    摘要: A memory cell with a small surface area is fabricated by forming source lines and data lines above and below and by running the channels to face up and down. The local data lines for each vertically stacked memory cell are connected to a global data line by way of separate selection by a molecular oxide semiconductor, and use of a large surface area is avoided by making joint use of peripheral circuits such as global data lines and sensing amplifiers by performing read and write operations in a timed multiplex manner. Moreover, data lines in multi-layers and memory cells (floating electrode cell) which are non-destructive with respect to readout are utilized to allow placement of memory cells at all intersecting points of word lines and data lines while having a folded data line structure. An improved noise tolerance is attained by establishing a standard threshold voltage for identical dummy cells even in any of the read verify, write verify and erase verify operations. A register to temporarily hold write data in a memory cell during writing is also used as a register to hold a flag showing that writing has ended during write verify. Also, a circuit comprised of one nMOS transistor is utilized as a means to change values on the write-end flag.

    摘要: Performance of a non-volatile semiconductor storage device which performs electron writing by hot electrons and hole erasure by hot holes is improved. A non-volatile memory cell which performs a writing operation by electrons and an erasure operation by holes has a p-type well region, isolation regions, a source region, and a drain region provided on an Si substrate. A control gate electrode is formed via a gate insulating film between the source region and the drain region. In a left-side side wall of the control gate electrode, a bottom Si oxide film, an electric charge holding film, a top Si oxide film, and a memory gate electrode are formed. The electric charge holding film is formed from an Si nitride film stoichiometrically excessively containing silicon.

    摘要: A charge holding insulating film in a memory cell is constituted by a laminated film composed of a bottom insulating film, a charge storage film, and a top insulating film on a semiconductor substrate. Further, by performing a plasma nitriding treatment to the bottom insulating film, a nitride region whose nitrogen concentration has a peak value and is 1 atom % or more is formed on the upper surface side in the bottom insulating film. The thickness of the nitride region is set to 0.5 nm or more and 1.5 nm or less, and the peak value of nitrogen concentration is set to 5 atom % or more and 40 atom % or less, and a position of the peak value of nitrogen concentration is set within 2 nm from the upper surface of the bottom insulating film, thereby suppressing an interaction between the bottom insulating film and the charge storage film.

    摘要: Conventionally, a MONOS type nonvolatile memory is fabricated by subjecting a silicon nitride film to ISSG oxidation to form a top silicon oxide film of ONO structure. If the ISSG oxidation conditions are severe, repeats of programming/erase operation cause increase of interface state density (Dit) and electron trap density. This does not provide a sufficient value of the on current, posing a problem in that the deterioration of charge trapping properties cannot be suppressed.For the solution to the problem, the silicon nitride film is oxidized by means of a high concentration ozone gas to form the top silicon oxide film.

    摘要: The present invention can promote the large capacity, high performance and high reliability of a semiconductor memory device by realizing high-performance of both the semiconductor device and a memory device when the semiconductor memory device is manufactured by stacking a memory device such as ReRAM or the phase change memory and the semiconductor device. After a polysilicon forming a selection device is deposited in an amorphous state at a low temperature, the crystallization of the polysilicon and the activation of impurities are briefly performed with heat treatment by laser annealing. When laser annealing is performed, the recording material located below the silicon subjected to the crystallization is completely covered with a metal film or with the metal film and an insulating film, thereby making it possible to suppress a temperature increase at the time of performing the annealing and to reduce the thermal load of the recording material.
