CONDUCTIVE MEMBERS FOR DIE ATTACH IN FLIP CHIP PACKAGES

Abstract:

In examples, a semiconductor package comprises a semiconductor die having an active surface; a conductive layer coupled to the active surface; and a polyimide layer coupled to the conductive layer. The package also comprises a conductive pillar coupled to the conductive layer and to the polyimide layer; a flux adhesive material coupled to the conductive pillar; and a solder layer coupled to the flux adhesive material. The package further includes a conductive terminal coupled to the solder layer and exposed to a surface of the package, the active surface of the semiconductor die facing the conductive terminal.
