  • Method for manufacturing flash memory device with dual floating gates and two bits per cell
    Patent number: 6271090
    Abstract: A method for manufacturing a flash memory device with dual floating gates is disclosed. The method use a self-align etching technique to form dual floating gates by using dual spacers as masks. First of all, a semiconductor substrate having a first insulating layer thereon and a first conductive layer formed over the first insulating layer is provided. Then a second insulating layer is formed and patterned to etch to form a trench therein. Next a dielectric layer is deposited and anisotropically etched to form dual spacers in the trench. After removing the second insulating layer, etching the first conductive layer to expose the first insulating layer, and removing the spacers sequentially, dual floating gates are formed.
