Abstract
Within an option selection device structure and a method for fabrication thereof there is formed a terminal metal layer and an option selection device at a co-planar level over a microelectronic substrate. The option selection device is passivated with: (1) a terminal metal passivation layer having an etch stop layer within its thickness; and (2) a bond pad passivation layer. There is simultaneously also formed through the bond pad passivation layer: (1) a via which accesses a bond pad formed contacting the terminal metal layer; and (2) an aperture over the option selection device which stops at the etch stop layer.
