    摘要: A two-bit flash memory cell includes a substrate, a gate oxide layer disposed on the substrate, a T-shaped gate on the gate oxide layer. A first charge storage layer is disposed at one side of and under the T-shaped gate. A second charge storage layer, which is separated from the first charge storage layer by a bottom portion of the T-shaped gate and the gate oxide layer, is disposed at the other side of and under the T-shaped gate. An insulating layer is disposed between the T-shaped gate and the gate oxide layer. A first source/drain region is disposed at one side of the T-shaped gate within the substrate. A second source/drain region is disposed at the other side of the T-shaped gate within the substrate.

    摘要: A DRAM structure on a silicon substrate has an active area, gate conductors, deep trench capacitors, and vertical transistors. The deep trench capacitors are formed at intersections of the active area and the gate conductors, and each deep trench capacitor is coupled electrically to the corresponding vertical transistor to form a memory cell. The transistor includes a gate, a source in a lateral side of the gate, and a drain in another lateral side of the gate The depth of the drain is different from the depth of the source.

    摘要: A partial vertical memory cell and fabrication method thereof. A semiconductor substrate is provided, in which two deep trenches having deep trench capacitors respectively are formed, and the deep trench capacitors are lower than a top surface of the semiconductor substrate. A portion of the semiconductor outside the deep trenches is removed to form a pillar between. The pillar is ion implanted to form an ion-doped area in the pillar corner acting as a S/D area. A gate dielectric layer and a conducting layer are conformally formed on the pillar sequentially. An isolation is formed in the semiconductor substrate beside the conducting layer. The conducting layer is defined to form a first gate and a second gate.
