摘要： Methods are provided that enable the ability to use a less aggressive liner processes, while producing structures known to give a desired high stress migration and electro-migration reliability. The present invention circumvents the issue of sputter damage of low k (on the order of 3.2 or less) dielectric by creating the via “anchors” (interlocked and interpenetrated vias) through chemical means. This allows the elimination or significant reduction of the sputter-etching process used to create the via penetration (“drilling, gouging”) into the line below in the barrier/seed metallization step. The present invention achieves the above, while maintaining a reliable copper fill and device structure.

摘要： A microelectronic structure and a method for fabricating the microelectronic structure use a dielectric layer that is located and formed upon a first conductor layer. An aperture is located through the dielectric layer. The aperture penetrates vertically into the first conductor layer and extends laterally within the first conductor layer beneath the dielectric layer while not reaching the dielectric layer, to form an extended and winged aperture. A contiguous via and interconnect may be formed anchored into the extended and winged aperture while using a plating method, absent voids.

摘要： The invention provides an improved network and methods of operation thereof for use in or with process control systems, computer-based manufacturing or production control systems, environmental control systems, industrial control system, and the like (collectively, “control systems”). Those networks utilize a unique combination of firewalls, intrusion detection systems, intrusion protection devices and/or other devices for hardening (e.g., security against hacking, intrusion or other mischievous conduct) and/or intrusion detection. The networks and methods have application, by way of example, in plants, sites and other facilities in which networks that support control systems interface with corporate, business or other networks.

摘要： The present invention relates to methods for post-etch, particularly post-RIE, removal of fluorocarbon-based residues from a hybrid dielectric structure. The hybrid dielectric structure contains a first dielectric material, and a line-level dielectric layer containing a second, different dielectric material, and wherein said second, different dielectric material comprises a polymeric thermoset dielectric material having a dielectric constant less than 4. Low energy electron beam or low temperature annealing is utilized by the present invention for removal of the fluorocarbon-based residues from such a hybrid dielectric structure, without damaging the low-k polymeric thermoset dielectric material contained in such a hybrid dielectric structure.
