    摘要: A method of forming split gate non-volatile memory cells on the same chip as logic and high voltage devices having HKMG logic gates. The method includes forming the source and drain regions, floating gates, control gates, and the poly layer for the erase gates and word line gates in the memory area of the chip. A protective insulation layer is formed over the memory area, and an HKMG layer and poly layer are formed on the chip, removed from the memory area, and patterned in the logic areas of the chip to form the logic gates having varying amounts of underlying insulation.

    摘要: Suspended charge storage regions are utilized for non-volatile storage to decrease parasitic interferences and increase charge retention in memory devices. Charge storage regions are suspended from an overlying intermediate dielectric material. The charge storage regions include an upper surface and a lower surface that extend in the row and column directions. The upper surface of the charge storage region is coupled to the overlying intermediate dielectric material. The lower surface faces the substrate surface and is separated from the substrate surface by a void. The charge storage region includes a first vertical sidewall and a second vertical sidewall that extend in the column direction and a third vertical sidewall and fourth vertical sidewall that extend in the row direction. The first, second, third, and fourth vertical sidewall are separated from neighboring features of the non-volatile memory by the void. The void may include a vacuum, air, gas, or a liquid.

    摘要: An electrically erasable programmable read only memory (EEPROM) cell may include a substrate including at least one active region, a floating gate adjacent the substrate, a write/erase gate defining a write/erase path for performing high voltage write and erase operations, and a read gate defining a read path for performing low voltage read operations, wherein the read path is distinct from the write/erase path. This allows for a smaller read gate oxide, thus allowing the cell size to be reduced. Further, the EEPROM cell may include two independently controllable read gates, thereby defining two independent transistors which allows better programming voltage isolation. This allows the memory array to be drawn using a common source instead of each column of EEPROM cells needing its own source line. This makes the array more scalable because the cell x-dimension would otherwise be limited by each column needing two metal 1 pitches.

    摘要: A memory device array with spaced apart parallel isolation regions (128) is formed in a semiconductor substrate (12), with an active region between each pair of adjacent isolation regions. Each isolation region includes a trench formed into the substrate surface and an insulation material formed in the trench. Portions of a top surface of the insulation material are recessed below the surface of the substrate. Each active region includes a column of memory cells each having spaced apart first and second regions (16) with a channel region (18) therebetween, a floating gate (22) over a first channel region portion, and a select gate (20) over a second channel region portion. The select gates are formed as continuous word lines extending perpendicular to the isolation regions and each forming the select gates for one row of the memory cells. Portions of each word line extend down into the trenches.

    摘要: Methods for preventing line collapse during the fabrication of NAND flash memory and other microelectronic devices that utilize closely spaced device structures with high aspect ratios are described. In some embodiments, one or more mechanical support structures may be provided to prevent the collapse of closely spaced device structures during fabrication. In one example, during fabrication of a NAND flash memory, one or more mechanical support structures may be set in place prior to performing a high aspect ratio word line etch for forming the NAND strings. The one or more mechanical support structures may comprise one or more fin supports that are arranged in a bit line direction. In another example, the one or more mechanical support structures may be developed during the word line etch for forming the NAND strings.

    摘要: A NAND flash memory chip includes wide openings in an inter-poly dielectric layer through which gaps are later etched to define structures such as select gates. Such select gates are asymmetric, with inter-poly dielectric on a side adjacent to a memory cell and no inter-poly dielectric on a side away from a memory cell. Gaps etched through such openings may also define peripheral devices.

    摘要: Die Erfindung bezieht sich auf eine EEPROM-Speicherzelle mit Floating-Gate (6), die als memristives Bauelement so konfiguriert ist, dass sie die Strom-Spannungs-Charakteristik eines Memristors durch eine reduzierte Beschaltung der EEPROM-Zelle annimmt, indem das Control-Gate (1) mit dem Source (3) verbunden wird und auf ein gemeinsames Potenzial mit- tels des so entstandenen Control-Gate- Anschlusses (8) gelegt wird (z. B. Massepotential, V = 0 Volt). Dies reduziert das ursprüngliche Dreipolbauelement zu einem Zweipolbauelement. Durch das Anlegen einer bipolaren Spannung am Drain-Anschluss (9) der reduzierten EEPROM-Zelle entsteht ein neues Bauelement, das sich in seiner u-i-Charakteristik wie ein memristives Bauelement, das als passives elektronisches Zweipolbauelement eingestuft ist, verhält. Der jeweilige zuletzt eingenommene Kanalwiderstandswert bleibt aufgrund des Floating-Gates (6) in der EEPROM-Zelle auch dann erhalten, wenn an den Anschlüssen (9) und (8) keine äußere Spannung mehr anliegt.
