Abstract
A method for forming a single die includes forming at least one first active device over a first substrate and at least one first metallic layer coupled to the first active device. At least one second metallic layer is formed over a second substrate, wherein the second substrate does not include any active device. The at least one first metallic layer is bonded with the at least one second metallic layer such that the first substrate and the second substrate constitute a single die.
