Abstract
A semiconductor device includes a semiconductor wafer. A plurality of pillar bumps is formed over the semiconductor wafer. A solder is deposited over the pillar bumps. The semiconductor wafer is singulated into a plurality of semiconductor die after forming the pillar bumps while the semiconductor wafer is on a carrier. An encapsulant is deposited around the semiconductor die and pillar bumps while the semiconductor die remains on the carrier. The encapsulant covers an active surface of the semiconductor die between the pillar bumps.
