  • Publication number: 20150303170
    Abstract: A singulated substrate for a semiconductor device may include a singulated unit substrate comprising circuit patterns on a top surface and a bottom surface of the singulated unit substrate. A semiconductor die may be bonded to the top surface of the singulated unit substrate. An encapsulation layer may encapsulate the semiconductor die and cover the top surface of the singulated unit substrate. The side surfaces of the singulated unit substrate between the top surface and bottom surface of the singulated unit substrate may be coplanar with side surfaces of the encapsulation layer. The semiconductor die may be electrically coupled to the singulated unit substrate utilizing solder bumps. Solder balls may be formed on the circuit patterns on the bottom surface of the singulated unit substrate. An underfill material may be formed between the semiconductor die and the top surface of the singulated unit substrate.
