Abstract:
A semiconductor package having a die with a sidewall protected by molding compound, and methods of forming the same are disclosed. The package includes a die with a first surface opposite a second surface and sidewalls extending between the first and second surfaces. A redistribution layer is formed on the first surface of each die. An area of the first surface of the die is greater than an area of the redistribution layer, such that a portion of the first surface of the die is exposed. When molding compound is formed over the die and the redistribution layer to form a semiconductor package, the molding compound is on the first surface of the die between an outer edge of the redistribution layer and an outer edge of the first surface. The molding compound is also on the sidewalls of the die, which provides protection against chipping or cracking during transport.
