Sputtering Target Bonding
NanoFoil®, a nanotechnology material, is used to simplify the sputtering target bonding process in a process called NanoBonding®. NanoBonding allows target bonders and target manufacturers to make reliable and repeatable bonds while increasing margins and lowering capital expenditures.
Features of NanoFoil® in Target Bonding:
- A reactive multi-layer foil
- Provides room temperature bonding
- Uniquely suited to bonding materials with dissimilar CTEs
- Lowers overall cost of solder bonding process: materials, capital expenditures, and personnel
- Provides uniform bond thickness
- Compatible with any solder
- Minimizes stress from CTE mismatch
- Adapts to bonding applications that require the higher precision demands of the semiconductor industry
- Delivers minimal voiding – up to 99% coverage
- Lowers overall cost of materials, capital expenditures, and personnel
- NanoBonds® any size target
Globally, target manufacturers, bond shops, and end users have realized the potential of NanoBonded sputtering targets.
NanoFoil® significantly improves existing planar target bonding methods through the use of localized heat. When activated, NanoFoil® 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.
NanoBonding® results in Flat & Parallel Assemblies
Maximum Y Deflection: 0.68 mm
Maximum Y Deflection: 0.038 mm
Residual stresses and deflections from NanoBonded targets are an order of magnitude less than conventional bonding [Von Mises Stress (MPa)].
NanoBonding® produces a strong, flat, low-stress bond that is highly thermally and electrically conductive. As a reactive multi-layer foil, NanoFoil® 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 NanoBond®, requires no expensive equipment and can be integrated into any process.

Indium wire is very different than the solder wire you find in hardware stores. To me, it’s like comparing a sports car and a go-kart. Each perform differently, are made for a very different set of uses. Indium wire is used for many unique purposes, such as sputtering target bonding (soldering),…
Ronnie Spraker is the supervisor of our NanoFoil® production department. Everyday, Ronnie and his team make reactive foils that are used all over the world. In addition to making foil, Ronnie’s team also uses NanoFoil® to NanoBond®sputtering targets – many of which are used…
People use indium in many forms - to create many different products. Certain forms fit various applications. Here are some of the many forms of pure indium that we provide: Ingot – this is the bulk form of indium, but it can still be customized. Sizes are available from small ‘finger’…
