Abstract: A method for forming fins includes forming a three-color hardmask fin pattern on a fin base layer. The three-color hardmask fin pattern includes hardmask fins of three mutually selectively etchable compositions. Some of the fins of the first color are etched away with a selective etch that does not remove fins of a second color or a third color and that leaves at least one fin of the first color behind. The fins of the second color are etched away. Fins are etched into the fin base layer by anisotropically etching around remaining fins of the first color and fins of the third color.

Abstract: Structures are provided that include a metal-insulator-metal capacitor (MIMCAP) present in the back-end-of-the-line (BEOL). The MIMCAP includes at least one of the bottom electrode and the top electrode having a via portion and a base portion that is formed utilizing a subtractive via etch process. Less via over etching occurs resulting in improved critical dimension control of the bottom and/or top electrodes that are formed by the subtractive via etch process. No bottom liner is present in the MIMCAP thus improving the resistance/capacitance of the device. Also, and in some embodiments, a reduced foot-print area is possible to bring the via portion of the bottom electrode closer to the top electrode.

Abstract: The present invention relates to integrated circuits and related method steps for forming an IC chip. The method steps result in semiconductor device structures that include redundant same via level formation using a top via subtractive etch and bottom via from dual damascene etch techniques. In embodiments, the same level redundancy via option is optional. Provision of redundant same via level connections using dual damascene processes improves device resistance and capacitive performance. Further method steps result in semiconductor device structures that include a direct super via connection bypassing subtractive etch metal level via formations. These highlighted method steps increase design flexibility—and reduce device footprint (by skipping a metal level) with the benefit of reduced via connection height and shorter metal connections.
