    摘要: A periodic pattern of conductor tracks with broader interspaces is produced by the application of a totally periodic pattern and subsequent removal of individual conductor tracks. An alternative method comprises the formation of a completely periodic hardmask, from which individual parts are removed. The modified hardmask is then used to etch a periodic pattern of conductor tracks with intermediate broader spaces.

    摘要: A method is provided for fabricating stacked non-volatile memory cells. A semiconductor wafer is provided having a plurality of diffusion regions forming buried bit lines. A charge-trapping layer and a conductive layer are deposited on the surface of the semiconductor wafer. Using a mask layer on top of the conductive layer, contact holes are formed wherein an insulating layer is formed. An etch stop layer is deposited on the surface of the semiconductor wafer. Above the etch stop layer, a dielectric layer is deposited and is patterned so as to form contact holes. Subsequently, the contact holes are enlarged through the etch stop layer and the insulating layer to the buried bit lines.

    摘要: Wordline stacks are arranged parallel at a distance from one another on a substrate surface. Bitlines are arranged transversely to the wordline stacks at a distance from one another. Source/drain regions are formed as doped regions in the vicinity of the wordline stacks. A resistive layer is disposed between a plurality of the source/drain regions and the bitlines and formed of a material having a resistance that is switched by an applied voltage. Source lines are arranged parallel to the wordline stacks so that they connect further pluralities of the source/drain regions.
