    摘要: Memory cell transistors with back-channel isolation are produced without using an SOI substrate. With the word line stack acting as a mask, the semiconductor material is etched on both sides of the world line, first anisotropically and then isotropically to widen the etch hole and form an undercut beneath the gate electrode and at a distance from the ONO storage layer forming the gate dielectric. The undercut is filled, whereby a buried oxide layer of at least 20 nm maximum thickness is formed underneath the channel region. The latter is p-doped at a density of at least 1017 cm−3.

    摘要: A memory array includes first, second, third and forth memory cell strings. Each of the first, second, third, and fourth memory cell strings includes a number of serially-coupled memory cells, including a first memory cell and a last memory cell. A first interconnect is coupled to a first bit line and to each of the first, second, third and fourth memory cell strings. The first interconnect includes first, second, third and fourth string input select gates. Each input select gate has a first terminal coupled to the first bit line, and a second terminal coupled to one of the respective first, second, third or fourth memory cell strings.

    摘要: A memory cell arrangement includes a first memory cell string having a plurality of serially source-to-drain-coupled transistors, at least some of them being memory cells, a second memory cell string having a plurality of serially source-to-drain-coupled transistors, at least some of them being memory cells. A dielectric material is between and above the first memory cell string and the second memory cell string. A source/drain line groove is defined in the dielectric material. The source/drain line groove extends from a source/drain region of one transistor of the first memory cell string to a source/drain region of the second memory cell string. Electrically conductive filling material is disposed in the source/drain line groove. Dielectric filling material is disposed in the source/drain line groove between the source/drain regions.

    摘要: A trench (2) is fabricated in a silicon body (1). The walls (4) of the trench are provided with a nitrogen implantation (6). An oxide layer between the source/drain regions (5) and a word line applied on the top side grows to a greater thickness than a lower oxide layer of an ONO storage layer fabricated as gate dielectric at the trench wall. Instead of the nitrogen implantation into the trench walls, it is possible to fabricate a metal silicide layer on the top sides of the source/drain regions in order to accelerate the oxide growth there.

    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.
