Method and apparatus for low temperature copper to copper bonding

摘要

A method comprising: coating a conductive bump on a first substrate with a conductive material to form a coated conductive bump; coating a conductive bump on a second substrate with a conductive material to form a coated conductive bump; and bonding the coated conductive bump on the first substrate to the coated conductive bump on the second substrate to electrically connect the first substrate to the second substrate.
