A method of patterning a thin film. The method includes forming a mask on a film to be patterned. The film is then etched in alignment with the mask to form a patterned film having a pair of laterally opposite sidewalls. A protective layer is formed on the pair of laterally opposite sidewalls. Next, the mask is removed from above the patterned film. After removing the mask from the patterned film, the protective layer is removed from the sidewalls.

Embodiments of the present invention describe a method of forming a multi-cornered film. According to the embodiments of the present invention, a photoresist mask is formed on a hard mask film formed on a film. The hard mask film is then patterned in alignment with the photoresist mask to produce a hard mask. The width of the photoresist mask is then reduced to form a reduced width photoresist mask. A first portion of the film is then etched in alignment with the hard mask. The hard mask is then etched in alignment with the reduced width photoresist mask to form a reduced width hard mask. A second portion of the film is then etched in alignment with the reduced width hard mask.
