Abstract:
1. A method for fabricating a microelectronic device, comprising: fabricating a plurality of dies on a microelectronic workpiece, the dies having integrated circuitry and bond-pads coupled to the integrated circuitry; constructing a redistribution assembly on the workpiece before separating the dies by depositing a dielectric layer over the dies, forming traces in the dielectric layer that are connected to the bond-pads on the dies, and constructing arrays of ball-pads corresponding to the dies, wherein the traces couple the ball-pads of an array to bond-pads of a corresponding die; attaching solder balls to the ball-pads before separating the dies; and covering the dielectric layer with a protective film that surrounds at least side portions of the solder by applying a deformable film while the deformable film is attached to a backing member balls.
