Patent ID: 7973374

Claim:
A device, comprising: a pad formed over a semiconductor substrate; a pillar formed over the semiconductor substrate adjacent to the pad; a bottom metal pattern over the pillar having a width that extends beyond a width of the pillar and extends to a position over a location where the pad is formed; a top metal pattern formed over the bottom metal pattern; a metal connector coupled to the top metal pattern; an air layer positioned between the bottom metal pattern and the pad; a metal film over the top metal pattern and semiconductor substrate at a predetermined interval from the semiconductor substrate, and having a plurality of etching holes formed therein; a metal wire formed over a top of the metal film, wherein the top metal pattern is electrically connected to the metal wire; and at least one contact electrode formed over a location corresponding to a position of the pillar and between the top metal pattern and the metal wire, wherein one side of a bottom surface of the bottom metal pattern is supported by the pillar, one side of an upper surface of the top metal pattern is supported by the contact electrode.
