| 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 |

| 20110140279 | SEMICONDUCTOR STRUCTURE INCORPORATING MULTIPLE NITRIDE LAYERS TO IMPROVE THERMAL DISSIPATION AWAY FROM A DEVICE AND A METHOD OF FORMING THE STRUCTURE - Disclosed are embodiments of a semiconductor structure that incorporates multiple nitride layers stacked between the center region of a device and a blanket oxide layer. These nitride layers are more thermally conductive than the blanket oxide layer and, thus provide improved heat dissipation away from the device. Also disclosed are embodiments of a method of forming such a semiconductor structure in conjunction with the formation of any of the following nitride layers during standard processing of other devices: a nitride hardmask layer (OP layer), a “sacrificial” nitride layer (SMT layer), a tensile nitride layer (WN layer) and/or a compressive nitride layer (WP layer). Optionally, the embodiments also incorporate incomplete contacts that extend through the blanket oxide layer into one or more of the nitride layers without contacting the device in order to further improve heat dissipation | 06-16-2011 |
