    摘要: A method for manufacturing memory cells is provided. First, a substrate is provided, wherein a liner layer and a material layer have already been sequentially formed on the substrate. Thereafter, a patterned mask layer is formed on the substrate. Then, the patterned mask layer is trimmed. Subsequently, a portion of the material layer, a portion of the liner layer and a portion of the substrate are removed by using the patterned mask layer as a mask to define a plurality of fin-structures in the substrate. Afterward, the patterned mask layer is removed and a plurality of isolation structures among the fin structures is formed. The surface of the isolation structures is lower than that of the fin structures. Following that, charge trapping structures are formed on the substrate, covering the fin structures. Succeeding, a portion of the charge trapping structures is removed to expose the material layer. Then, the treatment process turns the material layer into a protection layer. Subsequently, a gate is formed on the substrate and straddles the protection layer, the charge trapping structures and the fin structure. Afterward, source/drain regions are formed in the fin-structure exposed by both sides of the gate.

    摘要: A non-volatile memory cell comprising a substrate, a charge-trapping layer, a control gate, a first conductive state of source and drain, a lightly doped region and a second conductive state of pocket-doped region. The charge-trapping layer and the control gate are disposed over the substrate. A dielectric layer is disposed between the substrate, the charge-trapping layer and the control gate. The source and drain are disposed in the substrate on each side of the charge-trapping layer. The lightly doped region is disposed on the substrate surface between the source and the charge-trapping layer. The pocket-doped region is disposed within the substrate between the drain and the charge-trapping layer. Because there are asymmetrical configuration and different doped conductive states of implant structures, the programming speed of the memory cell is increased, the neighboring cell disturb issue is prevented, and the area occupation of the bit line selection transistor is reduced.

    摘要: An asymmetrically doped memory cell has first and second N+ doped junctions on a P substrate. A composite charge trapping layer is disposed over the P substrate and between the first and the second N+ doped junctions. A N− doped region is positioned adjacent to the first N+ doped junction and under the composite charge trapping layer. A P− doped region is positioned adjacent to the second N+ doped junction and under the composite charge trapping layer. The asymmetrically doped memory cell will store charges at the end of the composite charge trapping layer that is above the P− doped region. The asymmetrically doped memory cell can function as an electrically erasable programmable read only memory cell, and is capable of multiple level cell operations. A method for making an asymmetrically doped memory cell is also described.
