    摘要: According to the invention CBRAM cell is provided exhibiting a resistive switching effect offering the possibility to store multiple memory states in one cell by programming said memory cell to different resistance levels including at least a first memory state with a high resistance level representing a low-conductivity state of the memory cell and one memory state with a low resistance level representing a high-conductivity state of the memory cell, wherein the resistive switching effect is substantially based on a variation of the concentration of the metallic material incorporated or deposited in the matrix host material.

    摘要: The present invention relates to a reproducible conditioning during the manufacturing of a resistively switching CBRAM memory cell comprising a first electrode and a second electrode with an active material positioned therebetween. The active material is adapted to be placed in a more or less electroconductive state by means of electrochemical switching processes. A CBRAM memory cell manufactured pursuant to the method according to the invention has, due to the improved conditioning, more reliable and more distinctly evaluable electrical switching properties. Moreover, no more forming step is necessary with the method according to the present invention.

    摘要: A method which makes it possible to define in a patterning layer openings having a first dimension that is substantially less than the feature size that can be obtained lithographically includes applying a sacrificial layer made of a material that is different from that of the patterning layer in a predetermined layer thickness on the patterning layer. Afterward, a photoresist layer is applied on the surface of the sacrificial layer, and an opening having a second dimension is defined lithographically in the photoresist layer. Afterward, an etching angle is set in a manner dependent on the layer thickness of the sacrificial layer and also the first and second dimensions, and the sacrificial layer is etched at the etching angle set. Afterward, the patterning layer is etched, the sacrificial layer is removed and a filling material is introduced into the opening produced in the patterning layer.

    摘要: An integrated semiconductor memory includes a storage medium (6) arranged between two electrodes (10, 20), which storage medium may be a phase change medium, for example. The storage medium (6) can be put into a first state or a second state by means of an electric current, as a result of which an item of information can be stored. According to embodiments of the invention, a layer plane (L) is provided in which impurity particles made from a material (4) are embedded, as a result of which the current density in the storage medium is locally increased and the programming current required for reprogramming is reduced. As a result, the current consumption of memory elements containing a phase change medium is reduced, so that for the first time they can be embodied with minimal feature size, together with other components such as transistors, and integrated into a single semiconductor circuit and no longer have to be arranged in separate subcircuits.

    摘要: A nonvolatile integrated semiconductor memory has an arrangement of layers with a tunnel barrier layer and a charge-storing level. The charge-storing level has a dielectric material which stores scattered in charge carriers in a spatially fixed position. The tunnel barrier layer has a material through which high-energy charge carriers can tunnel. At least one interface surface of the charge-storing level has a greater microscopic roughness than the interface surface of the tunnel barrier layer, which is remote from the charge-storing level. The charge-storing level has a greater layer thickness in first regions than in second regions. This produces a relatively identical distribution and localization of positive and negative charge carriers in the lateral direction. The charge carriers which are scattered into the charge-storing level, therefore, recombine completely, so that the risk of unforeseen data loss during long-term operation of nonvolatile memories is reduced.
