At least a first portion of the redistribution layer may be electrically connected to the IC through a first opening in the repassivation layer. Furthermore, a substrate having a first antenna terminal may be provided, and a second opening may be formed in a nonconductive barrier present on at least one of the first antenna terminal and the first portion of the redistribution layer with an etchant. The first opening and the second opening may be nonoverlapping. The assembly may be attached to the substrate with an adhesive.
