A fan-out wafer level package includes a semiconductor die with a redistribution layer on a sidewall of the semiconductor die. A redistribution layer positioned over the die includes an extended portion that extends along the sidewall. The semiconductor die is encapsulated in a molding compound layer. The molding compound layer is positioned between the extended portion of the redistribution layer and the sidewall of the semiconductor die. Solder contacts, for electrically connecting the semiconductor device to an electronic circuit board, are positioned on the redistribution layer. The solder contacts and the sidewall of the redistribution layer can provide electrical contact on two different locations. Accordingly, the package can be used to improve interconnectivity by providing vertical and horizontal connections.
