To provide a pattern formation method capable of plotting a photosensitive material for an ultraviolet ray in a pattern with high throughput by a mask-less direct plotting exposure device having an irradiating light source being an h-line in a main wavelength.
The pattern formation method comprises: a step of forming, on a substrate, a first photosensitive material of low sensitivity to the h-line of the main wavelength irradiated from the mask-less direct plotting exposure device but of high sensitivity to energy line including the ultraviolet light ; a step of forming a second photosensitive material of high sensitivity on the first photosensitive material to the h-line of the main wavelength; a step of plotting a second pattern by using the mask-less direct plotting exposure device to the second photosensitive material; a step of developing the second photosensitive material; a step of collectively exposing the second photosensitive material and the first photosensitive material formed with the second pattern; a step of separating the second photosensitive material; and a step of forming an objective first pattern by developing the first photosensitive material.
