Abstract
A semiconductor device including two or more die stacks mounted to a substrate. The first die stack is mounted, at least partially encapsulated, and then tested. If the first die stack functions within predefined parameters, a second die stack is mounted on the first die stack, and then the device may undergo a second encapsulation process. Testing the first die stack before mounting the second improves yield by identifying faulty semiconductor die before all die are mounted within the semiconductor device.
