A barrier metal is a material used in integrated circuits to chemically isolate semiconductors from soft metal interconnects, while maintaining an electrical connection between them. For instance, a layer of barrier metal must surround every copper interconnect in modern integrated circuits, to prevent diffusion of copper into surrounding ...
A cargo barrier is a vehicle accessory installed into motor vehicles to aid occupancy safety when carrying loads or domestic pets, (usually dogs) in the rear section of a vehicle. Other terms used for cargo barriers include: dog guard, mesh partition, load separator, pet barrier, and mesh grille.
Metal barriers are used to encase the copper interconnects used in modern integrated circuits to avoid diffusion of Cu into the surrounding materials, such as insulators and the silicon substrate, and also, to prevent Cu contamination by elements diffusing from the insulators by surrounding every Cu interconnect with a layer of metal barriers ...
The diffusion barrier avoids interaction between Au and Ti/Cr and requires higher temperatures to form a reliable and uniform bond. Further, the very limited solubility of silicon in titanium and chromium can prevent the developing of Au-Si eutectic composition based on the diffusion of silicon through titanium into gold.
A sex offender who police said tried to "financially and emotionally manipulate" his victims has been jailed for 25 years. Stephen Gallagher, of Normandy Avenue in Colchester, was found guilty by ...
A Florida woman who said she was playing a game with her boyfriend when she zipped him up in a suitcase and left him to die has been sentenced to life in prison.

The gold film can also be deposited on a diffusion barrier film, i.e. oxide or nitride. [8] Also, an additional nano crystalline metal film, e.g. Ta, Cr, W, or Ti, can enhance the adhesion strength of the diffusion bond at decreased applied pressure and bonding temperature. [4]
