摘要: In a phase-change memory, an interface layer is inserted between a chalcogenide material layer and a plug. The interface layer is arranged so as not to cover the entire interface of a plug-like electrode. When the plug is formed at an upper part than the chalcogenide layer, the degree of integration is increased. The interface layer is formed by carrying out sputtering using an oxide target, or, by forming a metal film by carrying out sputtering using a metal target followed by oxidizing the metal film in an oxidation atmosphere such as oxygen radical, oxygen plasma, etc.

摘要: The invention provides a voltage applying structure having a reduced area penalty with respect to a data line. A wiring forming a global data line and a local data line formed in a p-type well region are connected via a select transistor. Two select lines are formed on a gate electrode of the select transistor. One select line is electrically connected to the gate electrode of the select transistor, however, the other select line is not connected to the select transistor. That is, an insulator film is formed between the select line and the gate electrode. As mentioned above, two select lines shorter than a gate length are provided on one select transistor. The select line is structured such as to be connected to the other select transistor.

摘要: A plurality of floating gates are formed on a principal surface of a semiconductor substrate that constitutes a nonvolatile semiconductor memory device through a first gate dielectric film. An auxiliary gate formed on the principal surface of the semiconductor substrate through a third gate dielectric film is formed on one adjacent side of the floating gates. A groove is formed on the other adjacent side of the floating gate, and an n-type diffusion layer is formed on a bottom side of the groove. A data line of the nonvolatile semiconductor memory device is constituted by an inversion layer formed on the principal surface of the semiconductor substrate to be opposed to an auxiliary gate by applying desired voltage to the auxiliary gate, and the n-type diffusion layer.

摘要: A technique that can realize high integration even for multilayered three-dimensional structures at low costs by improving the performance of the semiconductor device having recording or switching functions by employing a device structure that enables high precision controlling of the movement of ions in the solid electrolyte. The semiconductor element of the device is formed as follows; two or more layers are deposited with different components respectively between a pair of electrodes disposed separately in the vertical (z-axis) direction, then a pulse voltage is applied between those electrodes to form a conductive path. The resistance value of the path changes according to an information signal. Furthermore, a region is formed at a middle part of the conductive path. The region is used to accumulate a component that improves the conductivity of the path, thereby enabling the resistance value (rate) to response currently to the information signal. More preferably, an electrode should also be formed at least in either the x-axis or y-axis direction to apply a control voltage to the electrode.
