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.

摘要： A method of manufacturing a flash memory device is provided. Multiple stack structures each comprising a tunneling oxide layer and a first conductive layer are formed over a substrate. Thereafter, multiple embedded doping regions is formed in the substrate between the stack structures. A dielectric layer is formed over the substrate to cover the stack structures and then the dielectric layer is etched back and a portion of dielectric layer is remained on the stack structures. Using a portion of the remaining dielectric layer as a mask, a portion of the first conductive layer is removed. An inter-layer dielectric layer and a second conductive layer are sequentially formed over the first conductive layer. Because a self-aligned process is used to define the floating gate and the floating gate has a narrow-top/wide-bottom configuration, the fabrication process is simplified and the coupling ratio of the stack gate is increased.
