Patent ID: 7037805

Claim:
A method for bonding a die to a substrate, wherein the die includes one or more bonding regions each including a metallic surface, and wherein the substrate includes one or more bonding regions each including a metallic surface, the one or more bonding regions of the die being in registration with the one or more bonding regions of the substrate when the die is aligned with the substrate, the method comprising: providing a bonding material on at least selected bonding regions of the die and/or substrate, resulting in a cumulative amount of bonding material used for bonding the die to the substrate; aligning the die and/or substrate so that the one or more bonding regions of the die are in registration with the one or more bonding regions of the substrate; and applying a force between the die and substrate, wherein the force is at least 25000 Kg of force per cumulative gram of bonding material.
