Nano Foil, a nanotechnology material, is used to simplify the sputtering target bonding process in a process called Nano Bonding. Nano Bonding allows target bonders and target manufacturers to make reliable and repeatable bonds while increasing margins and lowering capital expenditures.

13. Nano Bonding applys to any size target
14. Globally, target manufacturers, bond shops, and end users have realized the potential of NanoBonded sputtering targets.
Nano Foil significantly improves existing planar target bonding methods through the use of localized heat. When activated, Nano Foil delivers localized heat that bonds similar or dissimilar materials in just a fraction of a second, in any environment, therefore eliminating the need for a standard furnace, torch, or laser. The rapid and versatile nature of this novel bonding method offers process cost reductions over traditional bonding methods.

Residual stresses and deflections from NanoBonded targets are an order of magnitude less than conventional bonding [Von Mises Stress (MPa)].
Nano Bonding produces a strong, flat, low-stress bond that is highly thermally and electrically conductive. As a reactive multi-layer foil, Nano Foil works by acting as a local heat source to melt adjacent solder layers without heating the target or backing plate materials. This allows the bonding of nearly any combination of sputtering target material and backing plate material, including ceramics to metals, irrespective of the difference in coefficient of thermal expansion (CTE). This process, called Nano Bond, requires no expensive equipment and can be integrated into any process.
