Assemblies comprising molybdenum and aluminum; and methods of utilizing interlayers in forming target/backing plate assemblies

摘要

The invention includes an assembly (130) having a physical vapor deposition target (102) separated from a backing plate (120) with a layer (104) consisting essentially of one or both of molybdenum and tantalum. The invention also includes an assembly comprising a backing plate of at least 99.9% aluminum bound to a target of at least 99.9% molybdenum through a bond having a strength of at least about 6,000 pounds per square inch (psi). Additionally, the invention includes a method of bonding a tungsten-containing material to an aluminum-containing material. A layer of molybdenum-containing material (104) is provided between the tungsten-containing material (102) and the aluminum-containing material (120); and is bonded to both the tungsten-containing material (102) and the aluminum-containing material (120).
