    摘要: An integrated circuit device includes a substrate including a first region and a second region. A pit is formed in the first region. A stack of active layers alternating with insulating layers is deposited in the pit. The stack includes a particular insulating layer. The particular insulating layer has a first thickness, where a sum of the first thickness, thickness of active layers, and thicknesses of other insulating layers is essentially equal to a depth of the pit. The first thickness is different than the thicknesses of the other insulating layers by an amount within a range of process variations for the depth of the pit, for the thicknesses of the active layers, and for the thicknesses of other insulating layers. The device includes a planarized surface over the first and second regions, where an uppermost one of the active layers has a top surface below the planarized surface.

    摘要: A device on an integrated circuit includes a stack of alternating semiconductor lines and insulating lines, and a gate structure over the stack of semiconductor lines. The gate structure includes a vertical portion adjacent the stack on the at least one side, and horizontal extension portions between the semiconductor lines. Sides of the insulating lines can be recessed relative to sides of the semiconductor lines, so at least one side of the stack includes recesses between semiconductor lines. The horizontal extension portions can be in the recesses. The horizontal extension portions have inside surfaces adjacent the sides of the insulating lines, and outside surfaces that can be flush with the sides of the semiconductor lines. The device may include a second gate structure spaced away from the first mentioned gate structure, and an insulating element between horizontal extension portions of the second gate structure and the first mentioned gate structure.

    摘要: A MOSFET fabrication process comprises nitridation of the dielectric silicon interface so that silicon-dangling bonds are connected with nitrogen atoms creating silicon—nitrogen bonds, which are stronger than silicon-hydrogen bonds. A tunnel dielectric is formed on the substrate. A nitride layer is then formed over the tunnel dielectric layer. The top of the nitride layer is then converted to an oxide and the interface between the substrate and the tunnel dielectric is nitrided simultaneously with conversion of the nitride layer to oxide.

    摘要: A method of fabricating a non-volatile memory device at least comprises steps as follows. First, a substrate on which a bottom dielectric layer is formed is provided. Then, impurities are introduced through the bottom dielectric layer to the substrate, so as to form a plurality of spaced doped regions on the substrate. The structure is thermally annealed for pushing the spaced doped regions to diffuse outwardly. After annealing, a charge trapping layer is formed on the bottom dielectric layer, and a top dielectric layer is formed on the charge trapping layer. Finally, a gate structure (such as a polysilicon layer and a silicide) is formed on the top dielectric layer.

    摘要: A NAND-type flash memory device includes asymmetric floating gates overlying respective wordlines. A given floating gate is sufficiently coupled to its respective wordline such that a large gate (i.e., wordline) bias voltage will couple the floating gate with a voltage which can invert the channel under the floating gate. The inversion channel under the floating gate can thus serve as the source/drain. As a result, the memory device does not need a shallow junction, or an assist-gate. In addition, the memory device exhibits relatively low floating gate-to-floating gate (FG-FG) interference.
