Title: Pitch reduced patterns relative to photolithography features
Inventor: TRAN LUAN
IPC: H01L21/027
Filed: 2006-03-03
Abstract: Differently-sized features of an integrated circuit (100) are formed by etching a substrate (110) using a mask which is formed by combining two separately formed patterns (177) and (230). Pitch multiplication is used to form the relatively small features (175) of the first pattern (177) and conventional photolithography used to form the relatively large features of the second pattern (230). Pitch multiplication is accomplished by patterning a photoresist and then etching that pattern into an amorphous carbon layer. Sidewall spacers (175) are then formed on the sidewalls of the amorphous carbon. The amorphous carbon is removed, leaving behind the sidewall spacers (175), which define the first mask pattern (177). A bottom anti-reflective coating (BARC) is then deposited around the spacers (175) to form a planar surface and a photoresist layer is formed over the BARC. The photoresist is next patterned by conventional photolithography to form the second pattern (230), which is then is transferred to the BARC. The combined pattern (177, 230) made out by the first pattern (177) and the second pattern (230) is transferred to an underlying amorphous silicon layer (150) and the pattern is subjected to a carbon strip to remove BARC and photoresist material. The combined pattern (177, 230) is then transferred to the silicon oxide layer (155) and then to an amorphous carbon mask layer (160). The combined mask pattern (177, 230), having features of difference sizes, is then etched into the underlying substrate (110) through the amorphous carbon hard mask layer (160).
