  • Publication number: 20110175158
    Abstract: A dual node memory device and methods for fabricating the device are provided. In one embodiment the method comprises forming a layered structure with an insulator layer, a charge storage layer, a buffer layer, and a sacrificial layer on a semiconductor substrate. The layers are patterned to form two spaced apart stacks and an exposed substrate portion between the stacks. A gate insulator and a gate electrode are formed on the exposed substrate, and the sacrificial layer and buffer layer are removed. An additional insulator layer is deposited overlying the charge storage layer to form insulator-storage layer-insulator memory storage areas on each side of the gate electrode. Sidewall spacers are formed at the sidewalls of the gate electrode overlying the storage areas. Bit lines are formed in the substrate spaced apart from the gate electrode, and a word line is formed that contacts the gate electrode and the sidewall spacers.

  • Patent number: 7952938
    Abstract: A memory device comprising an optimization component that facilitates erasing memory cells in a substantially homogeneous electromagnetic field and methods that facilitate erasing memory cells in a substantially homogeneous electromagnetic field are presented. The optimization component facilitates selecting a subset of memory cells to be erased at the same time, such that a memory cell in the subset of memory cells has two neighbor memory cells adjacent thereto that are in the subset of memory, or one neighbor memory cell adjacent thereto when the memory cell is an end-row memory cell. The optimization component facilitates performing a Fowler-Nordheim channel erase to erase the subset of memory cells, and a predetermined voltage potential associated with an erase command is applied to each cell of the subset of memory cells to facilitate reducing fringing effect associated with the electromagnetic fields applied to the cells during the erase.

  • Patent number: 7943980
    Abstract: A method for fabricating a memory device with a self-aligned trap layer which is optimized for scaling is disclosed. In the present invention, a non-conformal oxide is deposited over the charge trapping layer to form a thick oxide on top of the core source/drain region and a pinch off and a void at the top of the STI trench. An etch is performed on the pinch-off oxide and the thin oxide on the trapping layer on the STI oxide. The trapping layer is then partially etched between the core cells. A dip-off of the oxide on the trapping layer is performed. And a top oxide is formed. The top oxide converts the remaining trap layer to oxide and thus isolate the trap layer.

  • Publication number: 20110101527
    Abstract: The mechanism of forming a metal bump structure described above resolves the delamination issues between a conductive layer on a substrate and a metal bump connected to the conductive layer. The conductive layer can be a metal pad, a post passivation interconnect (PPI) layer, or a top metal layer. By performing an in-situ deposition of a protective conductive layer over the conductive layer (or base conductive layer), the under bump metallurgy (UBM) layer of the metal bump adheres better to the conductive layer and reduces the occurrence of interfacial delamination. In some embodiments, a copper diffusion barrier sub-layer in the UBM layer can be removed. In some other embodiments, the UBM layer is not needed if the metal bump is deposited by a non-plating process and the metal bump is not made of copper.

  • Publication number: 20110012823
    Abstract: A liquid crystal display and a shift register device thereof are provided. The shift register device includes a plurality of shift registers connected in series. In the invention, the channel lengths of the transistors, which are responsible to stop outputting scan signal, in the shift register are manufactured greater than the channel lengths of the transistors, which are responsible to output the scan signal, in the shift register. As a result, the degree of influence that the leakage currents of the N-type transistors being responsible to stop outputting the scan signal in the shift register affect the transistors being responsible to output the scan signal when the transistors being responsible to stop outputting the scan signal are in the sub-threshold region is reduced. And thus each of the shift registers is able to output the scan signal normally.
