Patent ID: 8653675

Claim:
An apparatus comprising: a package including a die and an encapsulant material formed over the die; a plurality of first topological features formed proximate to a first corner of an external surface of the encapsulant material and each of the first topological features spans from a first edge of the external surface to a second edge adjacent to the first edge, and the first topological features are configured to resist out-of-plane deformation of the package; and a plurality of second topological features formed proximate to a second corner of the external surface of the encapsulant material and each of the second topological features spans from the second edge to a third edge, wherein a central section of the second edge is completely free of any grooves and extends between the plurality of first topological features and the plurality of second topological features, wherein a completely grooveless region of the external surface extends from the central section of the second edge to a central section of the first edge and extends between the plurality of the first topological features and the plurality of the second topological features, and wherein the central section of the first edge is completely free of any grooves.
