ABSTRACT:
In a method for forming a photoresist pattern, a method for forming a capacitor, and a capacitor manufactured using the same, a light is selectively irradiated onto a selected portion of a photoresist film formed on a substrate. An interfered light generated from the irradiated light is transmitted through other portions of the photoresist film except a ring-shaped portion of the photoresist film having a predetermined width along a boundary of the selected portion. The photoresist film is exposed using the interfered light and the light irradiated onto the selected portion. A cylindrical photoresist pattern having a minute width may be formed through developing the photoresist film. With the cylindrical pattern, the capacitor can be easily formed.
