Abstract
A semiconductor package and a method for fabricating a semiconductor package are disclosed. The semiconductor package includes semiconductor chip attached to a circuit board that includes at least one lateral slot formed through the circuit board. Provision of the slot reduces stresses in the circuit board that are manifested by warpage. The semiconductor chip may be positioned in a central aperture of the circuit board and held therein by hardened encapsulant material.
