Claim:
1. A method of assembling an integrated circuit package comprising: providing a die having a first side and a second side disposed opposite to the first side; depositing an encapsulation material to encapsulate one or more surfaces of the die in the encapsulation material, the encapsulation material forming a first surface that is adjacent to the first side of the die and a second surface, opposite the first surface; and shaping the second surface of the encapsulation material to include one or more trenches that have a length as measured in a plane parallel to the second surface that is greater than a width that is measured in a plane parallel to the second surface and perpendicular to the length such that the encapsulation material varies in thickness resulting in one or more areas of a cross-section of the integrated circuit package as measured at a trench is thinner than one or more other areas of the cross-section as measured at a portion of the integrated circuit package that does not intersect with a trench.
