    • Disclosed herein is a fractal antenna for a vehicle. First and second radiation elements are downwardly inclined from an apex ridge, and disposed opposite each other on the left and right sides inside a radome for protecting the antenna. First and second parasitic elements are formed in an inner space which is formed by the first and second radiation elements. Further, the first and second parasitic elements are disposed to be parallel to and spaced apart from the respective first and second radiation elements at regular intervals, are downwardly inclined from an apex ridge, and are disposed opposite each other on the left and right sides. The first and second radiation elements are respectively formed on part of the upper surface of a first substrate and part of the upper surface of a second substrate in patterns each having a predetermined shape.

    • A method for manufacturing a floating gate includes: forming a tunnel oxide film on a semiconductor substrate; forming a polysilicon layer on a surface of the tunnel oxide film; forming a photosensitive film pattern on a surface of the polysilicon layer; depositing a by-product on the photosensitive film to generate a by-product mask; and using the by-product mask as an etching mask to etch the polysilicon layer, completing fabrication of the floating gate. The polysilicon layer may be etched by a simplified process using a by-product mask so as to fabricate the floating gate, the etch rate of the polysilicon layer may be increased to improve productivity, poly bridge problems may be eliminated, and total amount of a gas used in etching the polysilicon layer may be reduced, resulting in an increase in hardware margin and a decrease in the amount of the gas used in this method.
    • 制造浮栅的方法包括:在半导体衬底上形成隧道氧化膜; 在隧道氧化膜的表面上形成多晶硅层; 在所述多晶硅层的表面上形成感光膜图案; 在感光膜上沉积副产物以产生副产物掩模; 并且使用副产物掩模作为蚀刻掩模来蚀刻多晶硅层,完成浮栅的制造。 可以通过使用副产品掩模的简化工艺来蚀刻多晶硅层,以便制造浮栅,可以增加多晶硅层的蚀刻速率以提高生产率,可以消除多桥问题,并且总量 用于蚀刻多晶硅层的气体可能会降低,从而导致硬度裕度的增加和在该方法中使用的气体量的减少。
