20080284021 | Method for FEOL and BEOL Wiring - A method for forming a conductive structure of sub-lithographic dimension suitable for FEOL and BEOL semiconductor fabrication applications. The method includes forming a topographic feature of silicon-containing material on a substrate; forming a dielectric cap on the topographic feature; applying a mask structure to expose a pattern on a sidewall of the topographic feature, the exposed pattern corresponding to a conductive structure to be formed; depositing a metal at the exposed portions of the sidewall and forming one or more metal silicide conductive structures at the exposed sidewall portions; removing the dielectric cap layer; and removing the silicon-containing topographic feature. The result is the formation of one or more metal silicide conductor structures formed for a single lithographically defined feature. In example embodiments, the formed metal silicide conductive structures have a high aspect ratio, e.g., ranging from 1:1 to 20:1 (height to width dimension). | 11-20-2008 |
20090111225 | CMOS STRUCTURE AND METHOD INCLUDING MULTIPLE CRYSTALLOGRAPHIC PLANES - A complementary metal oxide semiconductor (CMOS) structure includes a semiconductor substrate having first mesa having a first ratio of channel effective horizontal surface area to channel effective vertical surface area. The CMOS structure also includes a second mesa having a second ratio of the same surface areas that is greater than the first ratio. A first device having a first polarity uses the first mesa as a channel and benefits from the enhanced vertical crystallographic orientation. A second device having a second polarity different from the first polarity uses the second mesa as a channel and benefits from the enhanced horizontal crystallographic orientation. | 04-30-2009 |
