    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 method for fabricating stacked non-volatile memory cells and non-volatile memory cell arrays are disclosed. A semiconductor wafer is provided having a charge-trapping layer and a conductive layer deposited on the surface of the semiconductor wafer. Using a mask layer on top of the conductive layer, contact holes are formed into which a contact fill material is deposited. A further conductive layer is deposited on the surface of the semiconductor wafer and is patterned so as to form word lines. The contact fill material is connected to a contact plug using the contact holes with the contact fill material as a landing pad.

    摘要: A semiconductor memory device includes a channel region, a gate electrode adjacent the channel region, and a charge-trapping layer between the channel region and the gate electrode. A voltage is applied between the gate electrode and the channel region to cause a first current of a first kind of charge carriers from the channel region to move into the charge-trapping layer and to cause a second current of a second kind of charge carriers from the gate electrode to move into the charge-trapping layer, until the value of the second current is at least half the amount of the first current value.

    摘要: Silicon nanocrystals are applied as storage layer (6) and removed using spacer elements (11) laterally with respect to the gate electrode (5). By means of an implantation of dopant, source/drain regions (2) are fabricated in a self-aligned manner with respect to the storage layer (6). The portions of the storage layer (6) are interrupted by the gate electrode (5) and the gate dielectric (4), so that a central portion of the channel region (3) is not covered by the storage layer (6). This memory cell is suitable as a multi-bit flash memory cell in a virtual ground architecture.
