METHOD OF FORMING PATTERN |
摘要 |
A method of forming a pattern is disclosed. First, N kinds of different photomask patterns are provided. Thereafter, the N kinds of different photomask patterns are transferred to a hard mask layer by using at least N−1 kinds of light sources with different wavelengths, so as to form a hard mask pattern, wherein one of the at least N−1 kinds of light sources with different wavelengths is a light source with a wavelength of 193 nm, and N is an integer of three or more. |
