The bonding material is an adhesive bonding material and in that the package comprises at least one diffusion barrier formed in a different material from the bonding material.A number of packages can be made simultaneously by a method comprising the step of providing a patterned intermediate bonding material on at least one of said first and second wafer aligning said first and second wafer and applying pressure to join the first wafer and the second wafer together by means of the patterned intermediate bonding material further comprising the step of providing a material suitable for forming a diffusion barrier on at least one of said first and second wafer, in addition to the bonding material.
