Abstract: The present disclosure relates to a semiconductor device package, which includes a carrier, a lid, a first adhesive layer and a constraint structure. The carrier includes a surface and a first conductive pad on the surface of the carrier. The lid includes a first portion and a second portion separated from the first portion on the surface of the carrier. The first conductive pad is disposed between the first portion of the lid and the surface of the carrier. The first adhesive layer includes a first portion between the first portion of the lid and the first conductive pad. The constraint structure surrounds the first adhesive layer.

Abstract: A structure for packaging a radio frequency identification (RFID) device is disclosed, which comprises a substrate, an antenna formed on the substrate, a RFID chip with a first side attached to the substrate and a second side having at least one signal pin exposed, at least one conductive contact plate placed on the substrate in contact with both the exposed signal pin and a portion of the antenna, and a protective film over the contact plate to secure the same to the substrate, wherein an electrical connection between the signal pin and the portion of the antenna is made through the contact plate.
