Sputtering targets are described that comprise: a) a target surface component comprising a target material; b) a core backing component having a coupling surface, a back surface and at least one open area, wherein the coupling surface is coupled to at least part of the target surface component; and wherein at least part of the target surface component fits into at least one open area of the core backing component. In some embodiments, the target surface component, the core backing component or a combination thereof have at least one surface area feature coupled to or located in the back surface of the core backing component, the target surface component or a combination thereof, wherein the surface area feature increases the cooling effectiveness of the target surface component. Methods of forming a sputtering target are also described that comprises: a) providing a target surface component comprising a surface material; b) providing a core backing component having a coupling surface, a back surface and at least one open area; c) coupling the coupling surface to at least part of the target surface component, wherein at least part of the target surface component fits into the at least one open area of the core backing component.
