DIE ATTACH SURFACE COPPER LAYER WITH PROTECTIVE LAYER FOR MICROELECTRONIC DEVICES
This abstract first appeared for US patent application 18816698 titled 'DIE ATTACH SURFACE COPPER LAYER WITH PROTECTIVE LAYER FOR MICROELECTRONIC DEVICES
Original Abstract Submitted
A microelectronic device is formed by thinning a substrate of the microelectronic device from a die attach surface of the substrate, and forming a copper-containing layer on the die attach surface of the substrate. A protective metal layer is formed on the copper-containing layer. Subsequently, the copper-containing layer is attached to a package member having a package die mount area. The protective metal layer may optionally be removed prior to attaching the copper-containing layer to the package member. Alternatively, the protective metal layer may be left on the copper-containing layer when the copper-containing layer is attached to the package member. A structure formed by the method is also disclosed.
