摘要: A method of forming an integrated circuit is disclosed. A second material layer is formed on a first material layer. A patterned mask layer having a plurality of first features with a first pitch P1 is formed on the second material layer. The second material layer is etched by using the patterned mask layer as a mask to form the first features in the second material layer. The patterned mask layer is trimmed. A plurality of dopants is introduced into the second material layer not covered by the trimmed patterned mask layer. The trimmed patterned mask layer is removed to expose un-doped second material layer. The un-doped second material layer is selectively removed to form a plurality of second features with a second pitch P2. P2 is smaller than P1.
