    Abstract: The present invention relates to a method of manufacturing a flash memory device. According to the present invention, a dielectric film is formed and an amorphous silicon layer is then formed to mitigate a topology generated by patterning of a first polysilicon layer in a cell region. The amorphous silicon layer serves as a protection layer of the dielectric film in the cell region when a gate oxide film in a peripheral circuit region is formed. Therefore, the present invention can not only improve the resistance of a word line in the cell region but also improve the film quality of the dielectric film and the gate oxide film in the peripheral circuit region.

    Abstract: The present invention relates to a method of forming a gate in a stack gate flash EEPROM cell. In order to preventing a lateral bird's beak from occurring in an ONO dielectric layer during a reoxidation process to be performed after a formation of a cell gate having a stack structure formed by stacking a floating gate, an ONO dielectric layer and a control gate, an oxide layer and a nitride layer are sequentially formed on an entire structure before the reoxidation and after a formation of the cell gate. The oxide layer serves to reduce a stress in depositing the nitride layer, and the nitride layer serves to prevent an occurrence of the lateral bird's beak of the ONO dielectric layer during the reoxidation process. Accordingly, the present invention prevents the lateral bird's beak of the ONO dielectric layer, thereby improving a speed of cell erase operation.

    Abstract: A backlight assembly has a lamp driving device for driving external electrode fluorescent lamps (EEFLs) parallel connected each other. The lamp driving device includes a power switch transistor, a diode, an inverter and a PWM controller. The transistor converts external DC power signal into pulse power signal based on switching signal, the diode prevents rush current from flowing into the transistor. The inverter converts the pulse power signal into AC power signal, raises voltage level of the AC power signal, and provides the lamps with the raised AC power signal. The PWM controller is activated by external on/off signal to provide the transistor with the switching signal so as to regulate voltage level of the AC power signal. The EEFLs can maintain a constant current level, and the backlight assembly can have characteristics of uniform luminance, high luminance and high heat efficiency.
