Claim:
1. A method comprising: providing a first and a second joining partner each having a first main surface, wherein at least a portion of the first main surfaces of the first and joining partners each comprise a metal layer; applying a plurality of separate spaced apart solder preforms to the metal layer of the first main surface of at least one of the first and second joining partners such that each solder preform directly contacts the metal layer of the first main surface of at least one of the first and second joining partners and such that the space between the solder preforms is devoid of material; positioning the first and second joining partners so that each solder preform of the plurality of solder preforms directly contacts the metal layers of the first main surfaces of the first and second joining partners; and melting the plurality of solder preforms under pressure such that the melted solder preforms combine to form a single continuous thin layer area interconnect comprising a diffusion solder bond which bonds together the metal layers of the of the first main surfaces of the first and second joining partners.
