Abstract

See full text

A method is provided for forming a current carrying structure with improved electrostatic discharge protection. The current carrying structure includes a conductive material layer and a voltage switchable dielectric layer adapted to switch between insulative and conductive at a predetermined voltage between the ground plane and the conductive material. An aperture is formed through the voltage switchable dielectric layer, and conductive material is deposited in the aperture to form a conductive pathway between the voltage switchable dielectric layer and another layer. A spark gap is created between the conductive material of the aperture and a ground portion using a laser to remove a portion of the conductive material layer from an area surrounding the aperture without substantially modifying physical properties of the underlying switchable dielectric layer.
