Patent ID: 8643138

Claim:
An integrated circuit isolator device, comprising: a first die including: first circuitry, and a first isolation barrier structure, coupled to the first circuitry, the first isolation barrier structure including a combined top plate/bonding pad and a bottom plate and insulative material therebetween, the bottom plate of the first isolation barrier structure being coupled to the first circuitry; a first circuitry keep-out region, situated on the first die proximate the first circuitry, wherein a metal layer of the first circuitry does not extend into the first circuitry keep-out region; a second die including: second circuitry, and a second isolation barrier structure, coupled to the second circuitry, the second isolation barrier structure including a combined top plate/bonding pad and a bottom plate and insulative material therebetween, the bottom plate of the second isolation barrier structure being coupled to the second circuitry; a bond wire coupling the combined top plate/bonding pad of the first isolation barrier structure to the combined top plate/bonding pad of the second isolation barrier structure, such that a signal propagates from the first circuitry, through the first and second isolation barrier structures, and to the second circuitry in voltage-isolated fashion.
