Abstract
A structure and method for creating an integrated circuit passivation (24) comprising, a circuit (16), a dielectric (18), and metal plates (20) over which an insulating layer (26) is disposed that electrically and hermetically isolates the circuit (16), and a discharge layer (32) that is deposited to form a passivation (24) that protects the circuit (16) from electrostatic discharges caused by, e.g., a finger, is disclosed.
