    摘要: A method of fabricating a flash memory is disclosed. The method begins a stacked gate on the substrate. A shallow junction doping is performed on a substrate having a stacked gate already formed thereon, with the stacked gate serving as a mask, so as to form a shallow junction doped region in the substrate adjacent to both sides of the stacked gate. A mask layer is formed on the substrate to cover a top surface and sidewalls of the stacked gate, while exposing portions of the shallow junction doped region. With the mask layer serving as a mask, a deep junction doping is performed on the substrate to form a deep junction doped region in the substrate adjacent to both sides of the mask layer. After the mask layer is removed, a thermal process is performed to form a source/drain region having both the shallow junction doped region and deep junction doped region.

    摘要: A fabrication method for a memory device is described. The method includes sequentially forming a pad oxide layer and a mask layer on a substrate, wherein the mask layer exposes a portion of the pad oxide layer. Thereafter, an ion implantation process is conducted to form a buried bit line in the substrate that is not covered by the mask layer. A raised bit line is then formed on the pad oxide layer above the buried bit line. The mask layer and the pad oxide layer are then removed, followed by forming a conformal gate oxide layer on the surface of the substrate and the raised bit line. A word line is further formed on the gate oxide layer.
