Original Abstract Submitted

An element, a bonded structure including the element, and a method of forming the same are disclosed. The bonded structure can include a first element having a first nonconductive field region and a first conductive feature. A surface of the first nonconductive field region and a surface of the first conductive feature at least partially defining a bonding surface of the first element. The first conductive feature includes a first portion and a second portion over the first portion and at least partially defines the surface of the first conductive feature. The first portion includes aluminum. The first conductive feature has a continuous sidewall along the first portion and the second portion. The second portion includes different metal composition from the first portion or comprising fluorine at the surface of the first conductive feature. The bonded structure can include a second element having a second nonconductive field region and a second conductive feature. A surface of the second nonconductive field region is directly bonded to the first nonconductive field region without an intervening adhesive along a bond interface and a surface of the second conductive feature is directly bonded to the second conductive feature without an intervening adhesive along the bond interface.
