Patent ID: 8072056

Claim:
An electrical circuit apparatus comprising a moisture ingress barrier, wherein the apparatus comprises: a first portion comprising: at least one side surface, a substantially planar connection surface, a substrate provided from a wafer, and one or more layers formed on the substrate terminating at the connection surface, wherein at least a portion of the at least one side surface is defined by the one or more layers, wherein the one or more layers comprise: at least one circuit device comprising electrical circuitry, wherein a perimeter region is defined between the at least one circuit device and the at least one side surface, and a metallic structure laterally surrounding the at least one circuit device and forming at least part of the moisture ingress barrier, wherein the metallic structure extends from the substrate to the connection surface and is located within the perimeter region; and a second portion comprising: at least one side surface, a substantially planar connection surface, and a substrate provided from a wafer, wherein at least a portion of the at least one surface is defined by the substrate, wherein the connection surface of the first portion is bonded to the connection surface of the second portion to form a hermetic interface proximate the metallic structure of the first portion, wherein the hermetic interface forms at least a part of the moisture ingress barrier.
