发明名称 Method of forming patterns
摘要 A method of forming patterns includes forming a photoresist film on a substrate. The photoresist film is exposed with a first dose of light to form a first area and a second area in the photoresist film. A first hole and a second hole are formed by removing the first area and the second area with a first developer. The photoresist film is re-exposed with a second dose of the light to form a third area in the photoresist film between the first hole and the second hole. A third hole is formed between the first hole and the second hole by removing the third area with a second developer.
