    摘要: For patterning during integrated circuit fabrication, a first pattern of first masking structures is formed, and a buffer layer is formed on exposed surfaces of the first masking structures. Also, a second pattern of second masking structures is formed in recesses between the buffer layer at sidewalls of the first masking structures. Furthermore, the first and masking structures are formed from spin-coating respective high carbon containing materials. Such first and second masking structures pattern a target layer with higher pitch than possible with traditional photolithography.

A third layer is formed on sidewalls and an upper surface of the first hard mask pattern, such that the third layer includes a top surface having a recess formed between two adjacent first line patterns. A second hard mask pattern including a plurality of second line patterns each extending in the first direction within the recess is formed. Then, the third layer is anisotropically etched to selectively expose an etch target layer between the first line patterns and the second line patterns. Then, the etch target layer is anisotropically etched using the first hard mask pattern and the second hard mask pattern as an etch mask.

    摘要: A method of forming fine patterns of a semiconductor device includes double etching by changing a quantity of producing polymer by-products to etch a film with different thicknesses in regions having different pattern densities. In a first etching, reactive ion etching (RIE) is performed upon a buffer layer and a hardmask layer both in a low-density pattern region and a high-density pattern region under a first etching ambient until an etch film is exposed in the low-density pattern region using mask patterns as an etch mask. In second etching for forming the hardmask patterns, using the mask patterns as an etch mask, the hardmask layer is etched until the etch film is exposed in the high-density pattern region while accumulating polymer by-products on the etch film in the low-density pattern region under a second etching ambient having polymer by-products produced greater than in the first etching ambient.
