Abstract

A semiconductor device has a substrate. A first component and second component are disposed over the substrate. The first component includes an antenna. A lid is disposed over the substrate between the first component and second component. An encapsulant is deposited over the substrate and lid. A conductive layer is formed over the encapsulant and in contact with the lid. A first portion of the conductive layer over the first component is removed using laser ablation.
