Abstract
Stress balanced semiconductor device packages, a method of forming, and a method of modifying a mold segment for use in the method are disclosed. A semiconductor die is attached to one side of a substrate having discrete conductive elements such as a ball grid array (BGA) on the opposing side thereof. An envelope of encapsulant material is disposed over the semiconductor die on one side of the substrate while a stress balancing structure comprising at least one stem member and at least one transversely extending branch member formed of encapsulant material is disposed over the opposing side of the substrate in an arrangement which does not interfere with the discrete conductive elements. The envelope and the stress balancing structure may be simultaneously formed.
