Patent ID: 8508036

Claim:
A microelectronic package comprising: (a) a polymeric dielectric layer having top and bottom surfaces, the dielectric layer having terminals exposed at the bottom surface; (b) a metallic wall bonded to the dielectric layer and projecting upwardly from the top surface of the dielectric layer and surrounding a region of the top surface; (c) a lid bonded to the wall and extending over the region of the top surface so that the lid, the wall and the dielectric layer cooperatively define an enclosed space; and (d) a microelectronic element disposed within the space and electrically connected to the terminals, the microelectronic element having a front surface, a rear surface, and opposed edges extending between the front surface and the rear surface, wherein the metallic wall surrounds the microelectronic element and a region of the top surface of the dielectric layer, and wherein the top surface of the metallic wall extends beyond the opposed edges of the microelectronic element, and the bottom surface of the metallic wall extends beyond the opposed edges of the microelectronic element.
