Abstract:
1. A semiconductor device comprising: a semiconductor chip having at least one connection element; a molded body covering the semiconductor chip except over a portion of the semiconductor chip that includes the at least one connection element, the molded body comprising at least one recess located outside a vertical boundary of the semiconductor chip; a redistribution layer disposed over the molded body including the at least one recess located outside the vertical boundary of the semiconductor chip, the redistribution layer comprises an insulating layer disposed over the molded body, at least one conducting line disposed over the insulating layer for connecting to the semiconductor chip, and a solder stop layer disposed over the insulating layer and the at least one conducting line; at least one solder element disposed over the at least one recess and a portion of the redistribution layer that are located outside the vertical boundary of the semiconductor chip, and wherein the redistribution layer is at least one conducting line extending from a first end contacting the at least one solder element along the at least one recess located outside the vertical boundary of the semiconductor chip to a second end contacting the at least one connection element of the semiconductor chip, and the insulating layer and the solder stop layer comprise an opening over the at least one recess for allowing solder material to enter into the at least one recess to form the at least one solder element.
