Thereafter, an organic anti-reflective layer(17a) is formed over the second polysilicon layer(16) to fill the space between the adjacent storage structures(14,15), and then cured and developed to partially remain in the space. Next, a photoresist layer(18) is coated on a resultant structure and then exposed only in a cell region. Then, the exposed photoresist layer(18) and the remaining anti-reflective layer(17a) are removed by development. Here the photoresist layer(18) is completely removed without staying the photoresist scum since the anti-reflective layer(17a) moderates the surfaces.

Abstract: PURPOSE: A method of etching a film for preventing generation of the surface roughness is to further dry-etch an upper surface of an etched structure, thereby preventing increase of leakage current in a capacitor. CONSTITUTION: A film(200') is formed on an interlayer dielectric(210). The interlayer dielectric is a silicon oxide film which is formed on a semiconductor substrate. For the patterning of the film, an etching mask pattern(220) is formed. By etching the film, an opening(230) is formed within the film. In a bottom surface and a sidewall of the opening, the surface roughness exists. To remove the surface roughness of the opening, the dry-etching is continuously performed. The dry-etching is effected independent of removing the etching mask pattern. The dry-etching must be performed after removing the etching mask pattern to prevent the organic material from being deposited on the sidewall and the bottom surface of the opening.
