Abstract
A method for forming a wirebond connection to an integrated circuit structure includes forming an insulative structure overlaying a corrosion susceptible metal wiring within the integrated circuit structure, defining a via through the insulative structure above a portion of the corrosion susceptible metal without exposing the portion of the corrosion susceptible metal, and attaching a wirebond material to the portion of the corrosion susceptible metal. The attaching process includes a preliminary process of exposing the portion of the corrosion susceptible metal. The attaching completely covers the portion of the corrosion susceptible metal.
