Abstract
Embodiments of the present disclosure include a semiconductor device and methods of forming a semiconductor device. An embodiment is a method of forming a semiconductor device, the method including bonding a die to a top surface of a first substrate, the die being electrically coupled to the first substrate, and forming a support structure on the top surface of the first substrate, the support structure being physically separated from the die with a top surface of the support structure being coplanar with a top surface of the die. The method further includes performing a sawing process on the first substrate, the sawing process sawing through the support structure.
