  • Patent number: 7192880
    Abstract: The present invention provides a method for etching a substrate 100. The method includes conducting a first etch on an anti-reflective layer 170 and a portion of a hardmask layer 140, 150 to form an opening 162 in the substrate 100. The first etch is designed to be selective to a remaining portion of the hardmask layer 140, 150. A second etch, which is different from the first etch, is conducted on a remaining portion of the hardmask 140, 150, and it is designed to be less selective than the first etch to the remaining portion of the hardmask 140, 150. The first etch allows polymer to build up on the sidewalls of the opening 162, and the polymer substantially remains on the sidewalls during the second etch.

  • Patent number: 7172965
    Abstract: After forming a stopper film on a semiconductor substrate having a copper wiring layer therein, an interlayer insulating film made of a low dielectric constant material is formed on the stopper film. Then, after forming a capping film on the interlayer insulating film, a resist film having a predetermined pattern is formed on the capping film. The capping film and the interlayer insulating film are etched using the resist film as a mask to form an opening reaching the stopper film. After that, the stopper film exposed by the opening is etched, with the resist film left in place, to form a via hole. Then, the resist film is removed by ashing.

  • Patent number: 7115525
    Abstract: Different sized features in the array and in the periphery of an integrated circuit are patterned on a substrate in a single step. In particular, a mixed pattern, combining two separately formed patterns, is formed on a single mask layer and then transferred to the underlying substrate. The first of the separately formed patterns is formed by pitch multiplication and the second of the separately formed patterns is formed by conventional photolithography. The first of the separately formed patterns includes lines that are below the resolution of the photolithographic process used to form the second of the separately formed patterns. These lines are made by forming a pattern on photoresist and then etching that pattern into an amorphous carbon layer. Sidewall pacers having widths less than the widths of the un-etched parts of the amorphous carbon are formed on the sidewalls of the amorphous carbon. The amorphous carbon is then removed, leaving behind the sidewall spacers as a mask pattern.
